The exact way to do it\ndepends on which build system you use, and is usually straightforward.\n\n### Build with CMake\n\nGoogle Test comes with a CMake build script\n([CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt))\nthat can be used on a wide range of platforms (\"C\" stands for cross-platform.).\nIf you don't have CMake installed already, you can download it for free from\n.\n\nCMake works by generating native makefiles or build projects that can be used in\nthe compiler environment of your choice. You can either build Google Test as a\nstandalone project or it can be incorporated into an existing CMake build for\nanother project.\n\n#### Standalone CMake Project\n\nWhen building Google Test as a standalone project, the typical workflow starts\nwith:\n\n mkdir mybuild # Create a directory to hold the build output.\n cd mybuild\n cmake ${GTEST_DIR} # Generate native build scripts.\n\nIf you want to build Google Test's samples, you should replace the last command\nwith\n\n cmake -Dgtest_build_samples=ON ${GTEST_DIR}\n\nIf you are on a \\*nix system, you should now see a Makefile in the current\ndirectory. Just type 'make' to build gtest.\n\nIf you use Windows and have Visual Studio installed, a `gtest.sln` file and\nseveral `.vcproj` files will be created. You can then build them using Visual\nStudio.\n\nOn Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.\n\n#### Incorporating Into An Existing CMake Project\n\nIf you want to use gtest in a project which already uses CMake, then a more\nrobust and flexible approach is to build gtest as part of that project directly.\nThis is done by making the GoogleTest source code available to the main build\nand adding it using CMake's `add_subdirectory()` command. This has the\nsignificant advantage that the same compiler and linker settings are used\nbetween gtest and the rest of your project, so issues associated with using\nincompatible libraries (eg debug/release), etc. are avoided. This is\nparticularly useful on Windows. Making GoogleTest's source code available to the\nmain build can be done a few different ways:\n\n* Download the GoogleTest source code manually and place it at a known\n location. This is the least flexible approach and can make it more difficult\n to use with continuous integration systems, etc.\n* Embed the GoogleTest source code as a direct copy in the main project's\n source tree. This is often the simplest approach, but is also the hardest to\n keep up to date. Some organizations may not permit this method.\n* Add GoogleTest as a git submodule or equivalent. This may not always be\n possible or appropriate. Git submodules, for example, have their own set of\n advantages and drawbacks.\n* Use CMake to download GoogleTest as part of the build's configure step. This\n is just a little more complex, but doesn't have the limitations of the other\n methods.\n\nThe last of the above methods is implemented with a small piece of CMake code in\na separate file (e.g. `CMakeLists.txt.in`) which is copied to the build area and\nthen invoked as a sub-build _during the CMake stage_. That directory is then\npulled into the main build with `add_subdirectory()`. For example:\n\nNew file `CMakeLists.txt.in`:\n\n```cmake\ncmake_minimum_required(VERSION 2.8.2)\n\nproject(googletest-download NONE)\n\ninclude(ExternalProject)\nExternalProject_Add(googletest\n GIT_REPOSITORY https://github.com/google/googletest.git\n GIT_TAG master\n SOURCE_DIR \"${CMAKE_CURRENT_BINARY_DIR}/googletest-src\"\n BINARY_DIR \"${CMAKE_CURRENT_BINARY_DIR}/googletest-build\"\n CONFIGURE_COMMAND \"\"\n BUILD_COMMAND \"\"\n INSTALL_COMMAND \"\"\n TEST_COMMAND \"\"\n)\n```\n\nExisting build's `CMakeLists.txt`:\n\n```cmake\n# Download and unpack googletest at configure time\nconfigure_file(CMakeLists.txt.in googletest-download/CMakeLists.txt)\nexecute_process(COMMAND ${CMAKE_COMMAND} -G \"${CMAKE_GENERATOR}\" .\n RESULT_VARIABLE result\n WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )\nif(result)\n message(FATAL_ERROR \"CMake step for googletest failed: ${result}\")\nendif()\nexecute_process(COMMAND ${CMAKE_COMMAND} --build .\n RESULT_VARIABLE result\n WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )\nif(result)\n message(FATAL_ERROR \"Build step for googletest failed: ${result}\")\nendif()\n\n# Prevent overriding the parent project's compiler/linker\n# settings on Windows\nset(gtest_force_shared_crt ON CACHE BOOL \"\" FORCE)\n\n# Add googletest directly to our build.

Eg\nadd_executable(example example.cpp)\ntarget_link_libraries(example gtest_main)\nadd_test(NAME example_test COMMAND example)\n```\n\nNote that this approach requires CMake 2.8.2 or later due to its use of the\n`ExternalProject_Add()` command. The above technique is discussed in more detail\nin [this separate article](http://crascit.com/2015/07/25/cmake-gtest/) which\nalso contains a link to a fully generalized implementation of the technique.\n\n##### Visual Studio Dynamic vs Static Runtimes\n\nBy default, new Visual Studio projects link the C runtimes dynamically but\nGoogle Test links them statically. This will generate an error that looks\nsomething like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch\ndetected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value\n'MDd_DynamicDebug' in main.obj\n\nGoogle Test already has a CMake option for this: `gtest_force_shared_crt`\n\nEnabling this option will make gtest link the runtimes dynamically too, and\nmatch the project in which it is included.\n\n#### C++ Standard Version\n\nAn environment that supports C++11 is required in order to successfully build\nGoogle Test. One way to ensure this is to specify the standard in the top-level\nproject, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this\nis not feasible, for example in a C project using Google Test for validation,\nthen it can be specified by adding it to the options for cmake via the\n`DCMAKE_CXX_FLAGS` option.\n\n### Tweaking Google Test\n\nGoogle Test can be used in diverse environments. The default configuration may\nnot work (or may not work well) out of the box in some environments. However,\nyou can easily tweak Google Test by defining control macros on the compiler\ncommand line. Generally, these macros are named like `GTEST_XYZ` and you define\nthem to either 1 or 0 to enable or disable a certain feature.\n\nWe list the most frequently used macros below. For a complete list, see file\n[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h).\n\n### Multi-threaded Tests\n\nGoogle Test is thread-safe where the pthread library is available. After\n`#include \"gtest/gtest.h\"`, you can check the\n`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is\n`#defined` to 1, no if it's undefined.).\n\nIf Google Test doesn't correctly detect whether pthread is available in your\nenvironment, you can force it with\n\n -DGTEST_HAS_PTHREAD=1\n\nor\n\n -DGTEST_HAS_PTHREAD=0\n\nWhen Google Test uses pthread, you may need to add flags to your compiler and/or\nlinker to select the pthread library, or you'll get link errors. If you use the\nCMake script or the deprecated Autotools script, this is taken care of for you.\nIf you use your own build script, you'll need to read your compiler and linker's\nmanual to figure out what flags to add.\n\n### As a Shared Library (DLL)\n\nGoogle Test is compact, so most users can build and link it as a static library\nfor the simplicity. You can choose to use Google Test as a shared library (known\nas a DLL on Windows) if you prefer.\n\nTo compile *gtest* as a shared library, add\n\n -DGTEST_CREATE_SHARED_LIBRARY=1\n\nto the compiler flags. You'll also need to tell the linker to produce a shared\nlibrary instead - consult your linker's manual for how to do it.\n\nTo compile your *tests* that use the gtest shared library, add\n\n -DGTEST_LINKED_AS_SHARED_LIBRARY=1\n\nto the compiler flags.\n\nNote: while the above steps aren't technically necessary today when using some\ncompilers (e.g. GCC), they may become necessary in the future, if we decide to\nimprove the speed of loading the library (see\n for details). Therefore you are recommended\nto always add the above flags when using Google Test as a shared library.\nOtherwise a future release of Google Test may break your build script.\n\n### Avoiding Macro Name Clashes\n\nIn C++, macros don't obey namespaces. Therefore two libraries that both define a\nmacro of the same name will clash if you `#include` both definitions. In case a\nGoogle Test macro clashes with another library, you can force Google Test to\nrename its macro to avoid the conflict.\n\nSpecifically, if both Google Test and some other code define macro FOO, you can\nadd\n\n -DGTEST_DONT_DEFINE_FOO=1\n\nto the compiler flags to tell Google Test to change the macro's name from `FOO`\nto `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`, or `TEST`. For\nexample, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write\n\n GTEST_TEST(SomeTest, DoesThis) { ... }\n\ninstead of\n\n TEST(SomeTest, DoesThis) { ... }\n\nin order to define a test.\n" }, { "path": "test/googletest/cmake/Config.cmake.in", "content": "@PACKAGE_INIT@\ninclude(CMakeFindDependencyMacro)\nif (@GTEST_HAS_PTHREAD@)\n set(THREADS_PREFER_PTHREAD_FLAG @THREADS_PREFER_PTHREAD_FLAG@)\n find_dependency(Threads)\nendif()\n\ninclude(\"${CMAKE_CURRENT_LIST_DIR}/@targets_export_name@.cmake\")\ncheck_required_components(\"@project_name@\")\n" }, { "path": "test/googletest/cmake/gtest.pc.in", "content": "libdir=@CMAKE_INSTALL_FULL_LIBDIR@\nincludedir=@CMAKE_INSTALL_FULL_INCLUDEDIR@\n\nName: gtest\nDescription: GoogleTest (without main() function)\nVersion: @PROJECT_VERSION@\nURL: https://github.com/google/googletest\nLibs: -L${libdir} -lgtest @CMAKE_THREAD_LIBS_INIT@\nCflags: -I${includedir} @GTEST_HAS_PTHREAD_MACRO@\n" }, { "path": "test/googletest/cmake/gtest_main.pc.in", "content": "libdir=@CMAKE_INSTALL_FULL_LIBDIR@\nincludedir=@CMAKE_INSTALL_FULL_INCLUDEDIR@\n\nName: gtest_main\nDescription: GoogleTest (with main() function)\nVersion: @PROJECT_VERSION@\nURL: https://github.com/google/googletest\nRequires: gtest\nLibs: -L${libdir} -lgtest_main @CMAKE_THREAD_LIBS_INIT@\nCflags: -I${includedir} @GTEST_HAS_PTHREAD_MACRO@\n" }, { "path": "test/googletest/cmake/internal_utils.cmake", "content": "# Defines functions and macros useful for building Google Test and\n# Google Mock.\n#\n# Note:\n#\n# - This file will be run twice when building Google Mock (once via\n# Google Test's CMakeLists.txt, and once via Google Mock's).\n# Therefore it shouldn't have any side effects other than defining\n# the functions and macros.\n#\n# - The functions/macros defined in this file may depend on Google\n# Test and Google Mock's option() definitions, and thus must be\n# called *after* the options have been defined.\n\nif (POLICY CMP0054)\n cmake_policy(SET CMP0054 NEW)\nendif (POLICY CMP0054)\n\n# Tweaks CMake's default compiler/linker settings to suit Google Test's needs.\n#\n# This must be a macro(), as inside a function string() can only\n# update variables in the function scope.\nmacro(fix_default_compiler_settings_)\n if (MSVC)\n # For MSVC, CMake sets certain flags to defaults we want to override.\n # This replacement code is taken from sample in the CMake Wiki at\n # https://gitlab.kitware.com/cmake/community/wikis/FAQ#dynamic-replace.\n foreach (flag_var\n CMAKE_C_FLAGS CMAKE_C_FLAGS_DEBUG CMAKE_C_FLAGS_RELEASE\n CMAKE_C_FLAGS_MINSIZEREL CMAKE_C_FLAGS_RELWITHDEBINFO\n CMAKE_CXX_FLAGS CMAKE_CXX_FLAGS_DEBUG CMAKE_CXX_FLAGS_RELEASE\n CMAKE_CXX_FLAGS_MINSIZEREL CMAKE_CXX_FLAGS_RELWITHDEBINFO)\n if (NOT BUILD_SHARED_LIBS AND NOT gtest_force_shared_crt)\n # When Google Test is built as a shared library, it should also use\n # shared runtime libraries.

This document\nwill show you more assertions as well as how to construct complex failure\nmessages, propagate fatal failures, reuse and speed up your test fixtures, and\nuse various flags with your tests.\n\n## More Assertions\n\nThis section covers some less frequently used, but still significant,\nassertions.\n\n### Explicit Success and Failure\n\nThese three assertions do not actually test a value or expression. Instead, they\ngenerate a success or failure directly. Like the macros that actually perform a\ntest, you may stream a custom failure message into them.\n\n```c++\nSUCCEED();\n```\n\nGenerates a success. This does **NOT** make the overall test succeed. A test is\nconsidered successful only if none of its assertions fail during its execution.\n\nNOTE: `SUCCEED()` is purely documentary and currently doesn't generate any\nuser-visible output. However, we may add `SUCCEED()` messages to googletest's\noutput in the future.\n\n```c++\nFAIL();\nADD_FAILURE();\nADD_FAILURE_AT(\"file_path\", line_number);\n```\n\n`FAIL()` generates a fatal failure, while `ADD_FAILURE()` and `ADD_FAILURE_AT()`\ngenerate a nonfatal failure. These are useful when control flow, rather than a\nBoolean expression, determines the test's success or failure. For example, you\nmight want to write something like:\n\n```c++\nswitch(expression) {\n case 1:\n ... some checks ...\n case 2:\n ... some other checks ...\n default:\n FAIL() << \"We shouldn't get here.\";\n}\n```\n\nNOTE: you can only use `FAIL()` in functions that return `void`. See the\n[Assertion Placement section](#assertion-placement) for more information.\n\n### Exception Assertions\n\nThese are for verifying that a piece of code throws (or does not throw) an\nexception of the given type:\n\nFatal assertion | Nonfatal assertion | Verifies\n------------------------------------------ | ------------------------------------------ | --------\n`ASSERT_THROW(statement, exception_type);` | `EXPECT_THROW(statement, exception_type);` | `statement` throws an exception of the given type\n`ASSERT_ANY_THROW(statement);` | `EXPECT_ANY_THROW(statement);` | `statement` throws an exception of any type\n`ASSERT_NO_THROW(statement);` | `EXPECT_NO_THROW(statement);` | `statement` doesn't throw any exception\n\nExamples:\n\n```c++\nASSERT_THROW(Foo(5), bar_exception);\n\nEXPECT_NO_THROW({\n int n = 5;\n Bar(&n);\n});\n```\n\n**Availability**: requires exceptions to be enabled in the build environment\n\n### Predicate Assertions for Better Error Messages\n\nEven though googletest has a rich set of assertions, they can never be complete,\nas it's impossible (nor a good idea) to anticipate all scenarios a user might\nrun into. Therefore, sometimes a user has to use `EXPECT_TRUE()` to check a\ncomplex expression, for lack of a better macro. This has the problem of not\nshowing you the values of the parts of the expression, making it hard to\nunderstand what went wrong. As a workaround, some users choose to construct the\nfailure message by themselves, streaming it into `EXPECT_TRUE()`. However, this\nis awkward especially when the expression has side-effects or is expensive to\nevaluate.\n\ngoogletest gives you three different options to solve this problem:\n\n#### Using an Existing Boolean Function\n\nIf you already have a function or functor that returns `bool` (or a type that\ncan be implicitly converted to `bool`), you can use it in a *predicate\nassertion* to get the function arguments printed for free:\n\n\n\n| Fatal assertion | Nonfatal assertion | Verifies |\n| --------------------------------- | --------------------------------- | --------------------------- |\n| `ASSERT_PRED1(pred1, val1)` | `EXPECT_PRED1(pred1, val1)` | `pred1(val1)` is true |\n| `ASSERT_PRED2(pred2, val1, val2)` | `EXPECT_PRED2(pred2, val1, val2)` | `pred1(val1, val2)` is true |\n| `...` | `...` | `...` |\n\n\nIn the above, `predn` is an `n`-ary predicate function or functor, where `val1`,\n`val2`, ..., and `valn` are its arguments. The assertion succeeds if the\npredicate returns `true` when applied to the given arguments, and fails\notherwise. When the assertion fails, it prints the value of each argument. In\neither case, the arguments are evaluated exactly once.\n\nHere's an example. Given\n\n```c++\n// Returns true if m and n have no common divisors except 1.\nbool MutuallyPrime(int m, int n) { ... }\n\nconst int a = 3;\nconst int b = 4;\nconst int c = 10;\n```\n\nthe assertion\n\n```c++\n EXPECT_PRED2(MutuallyPrime, a, b);\n```\n\nwill succeed, while the assertion\n\n```c++\n EXPECT_PRED2(MutuallyPrime, b, c);\n```\n\nwill fail with the message\n\n```none\nMutuallyPrime(b, c) is false, where\nb is 4\nc is 10\n```\n\n> NOTE:\n>\n> 1. If you see a compiler error \"no matching function to call\" when using\n> `ASSERT_PRED*` or `EXPECT_PRED*`, please see\n> [this](faq.md#the-compiler-complains-no-matching-function-to-call-when-i-use-assert-pred-how-do-i-fix-it)\n> for how to resolve it.\n\n#### Using a Function That Returns an AssertionResult\n\nWhile `EXPECT_PRED*()` and friends are handy for a quick job, the syntax is not\nsatisfactory: you have to use different macros for different arities, and it\nfeels more like Lisp than C++. The `::testing::AssertionResult` class solves\nthis problem.\n\nAn `AssertionResult` object represents the result of an assertion (whether it's\na success or a failure, and an associated message). You can create an\n`AssertionResult` using one of these factory functions:\n\n```c++\nnamespace testing {\n\n// Returns an AssertionResult object to indicate that an assertion has\n// succeeded.\nAssertionResult AssertionSuccess();\n\n// Returns an AssertionResult object to indicate that an assertion has\n// failed.\nAssertionResult AssertionFailure();\n\n}\n```\n\nYou can then use the `<<` operator to stream messages to the `AssertionResult`\nobject.\n\nTo provide more readable messages in Boolean assertions (e.g. `EXPECT_TRUE()`),\nwrite a predicate function that returns `AssertionResult` instead of `bool`. For\nexample, if you define `IsEven()` as:\n\n```c++\n::testing::AssertionResult IsEven(int n) {\n if ((n % 2) == 0)\n return ::testing::AssertionSuccess();\n else\n return ::testing::AssertionFailure() << n << \" is odd\";\n}\n```\n\ninstead of:\n\n```c++\nbool IsEven(int n) {\n return (n % 2) == 0;\n}\n```\n\nthe failed assertion `EXPECT_TRUE(IsEven(Fib(4)))` will print:\n\n```none\nValue of: IsEven(Fib(4))\n Actual: false (3 is odd)\nExpected: true\n```\n\ninstead of a more opaque\n\n```none\nValue of: IsEven(Fib(4))\n Actual: false\nExpected: true\n```\n\nIf you want informative messages in `EXPECT_FALSE` and `ASSERT_FALSE` as well\n(one third of Boolean assertions in the Google code base are negative ones), and\nare fine with making the predicate slower in the success case, you can supply a\nsuccess message:\n\n```c++\n::testing::AssertionResult IsEven(int n) {\n if ((n % 2) == 0)\n return ::testing::AssertionSuccess() << n << \" is even\";\n else\n return ::testing::AssertionFailure() << n << \" is odd\";\n}\n```\n\nThen the statement `EXPECT_FALSE(IsEven(Fib(6)))` will print\n\n```none\n Value of: IsEven(Fib(6))\n Actual: true (8 is even)\n Expected: false\n```\n\n#### Using a Predicate-Formatter\n\nIf you find the default message generated by `(ASSERT|EXPECT)_PRED*` and\n`(ASSERT|EXPECT)_(TRUE|FALSE)` unsatisfactory, or some arguments to your\npredicate do not support streaming to `ostream`, you can instead use the\nfollowing *predicate-formatter assertions* to *fully* customize how the message\nis formatted:\n\nFatal assertion | Nonfatal assertion | Verifies\n------------------------------------------------ | ------------------------------------------------ | --------\n`ASSERT_PRED_FORMAT1(pred_format1, val1);` | `EXPECT_PRED_FORMAT1(pred_format1, val1);` | `pred_format1(val1)` is successful\n`ASSERT_PRED_FORMAT2(pred_format2, val1, val2);` | `EXPECT_PRED_FORMAT2(pred_format2, val1, val2);` | `pred_format2(val1, val2)` is successful\n`...` | `...` | ...\n\nThe difference between this and the previous group of macros is that instead of\na predicate, `(ASSERT|EXPECT)_PRED_FORMAT*` take a *predicate-formatter*\n(`pred_formatn`), which is a function or functor with the signature:\n\n```c++\n::testing::AssertionResult PredicateFormattern(const char* expr1,\n const char* expr2,\n ...\n const char* exprn,\n T1 val1,\n T2 val2,\n ...\n Tn valn);\n```\n\nwhere `val1`, `val2`, ..., and `valn` are the values of the predicate arguments,\nand `expr1`, `expr2`, ..., and `exprn` are the corresponding expressions as they\nappear in the source code. The types `T1`, `T2`, ..., and `Tn` can be either\nvalue types or reference types. For example, if an argument has type `Foo`, you\ncan declare it as either `Foo` or `const Foo&`, whichever is appropriate.\n\nAs an example, let's improve the failure message in `MutuallyPrime()`, which was\nused with `EXPECT_PRED2()`:\n\n```c++\n// Returns the smallest prime common divisor of m and n,\n// or 1 when m and n are mutually prime.\nint SmallestPrimeCommonDivisor(int m, int n) { ... }\n\n// A predicate-formatter for asserting that two integers are mutually prime.\n::testing::AssertionResult AssertMutuallyPrime(const char* m_expr,\n const char* n_expr,\n int m,\n int n) {\n if (MutuallyPrime(m, n)) return ::testing::AssertionSuccess();\n\n return ::testing::AssertionFailure() << m_expr << \" and \" << n_expr\n << \" (\" << m << \" and \" << n << \") are not mutually prime, \"\n << \"as they have a common divisor \" << SmallestPrimeCommonDivisor(m, n);\n}\n```\n\nWith this predicate-formatter, we can use\n\n```c++\n EXPECT_PRED_FORMAT2(AssertMutuallyPrime, b, c);\n```\n\nto generate the message\n\n```none\nb and c (4 and 10) are not mutually prime, as they have a common divisor 2.\n```\n\nAs you may have realized, many of the built-in assertions we introduced earlier\nare special cases of `(EXPECT|ASSERT)_PRED_FORMAT*`. In fact, most of them are\nindeed defined using `(EXPECT|ASSERT)_PRED_FORMAT*`.\n\n### Floating-Point Comparison\n\nComparing floating-point numbers is tricky. Due to round-off errors, it is very\nunlikely that two floating-points will match exactly. Therefore, `ASSERT_EQ` 's\nnaive comparison usually doesn't work. And since floating-points can have a wide\nvalue range, no single fixed error bound works. It's better to compare by a\nfixed relative error bound, except for values close to 0 due to the loss of\nprecision there.\n\nIn general, for floating-point comparison to make sense, the user needs to\ncarefully choose the error bound. If they don't want or care to, comparing in\nterms of Units in the Last Place (ULPs) is a good default, and googletest\nprovides assertions to do this. Full details about ULPs are quite long; if you\nwant to learn more, see\n[here](https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/).\n\n#### Floating-Point Macros\n\n\n\n| Fatal assertion | Nonfatal assertion | Verifies |\n| ------------------------------- | ------------------------------- | ---------------------------------------- |\n| `ASSERT_FLOAT_EQ(val1, val2);` | `EXPECT_FLOAT_EQ(val1, val2);` | the two `float` values are almost equal |\n| `ASSERT_DOUBLE_EQ(val1, val2);` | `EXPECT_DOUBLE_EQ(val1, val2);` | the two `double` values are almost equal |\n\n\n\nBy \"almost equal\" we mean the values are within 4 ULP's from each other.\n\nThe following assertions allow you to choose the acceptable error bound:\n\n\n\n| Fatal assertion | Nonfatal assertion | Verifies |\n| ------------------------------------- | ------------------------------------- | -------------------------------------------------------------------------------- |\n| `ASSERT_NEAR(val1, val2, abs_error);` | `EXPECT_NEAR(val1, val2, abs_error);` | the difference between `val1` and `val2` doesn't exceed the given absolute error |\n\n\n\n#### Floating-Point Predicate-Format Functions\n\nSome floating-point operations are useful, but not that often used. In order to\navoid an explosion of new macros, we provide them as predicate-format functions\nthat can be used in predicate assertion macros (e.g. `EXPECT_PRED_FORMAT2`,\netc).\n\n```c++\nEXPECT_PRED_FORMAT2(::testing::FloatLE, val1, val2);\nEXPECT_PRED_FORMAT2(::testing::DoubleLE, val1, val2);\n```\n\nVerifies that `val1` is less than, or almost equal to, `val2`. You can replace\n`EXPECT_PRED_FORMAT2` in the above table with `ASSERT_PRED_FORMAT2`.\n\n### Asserting Using gMock Matchers\n\n[gMock](../../googlemock) comes with a library of matchers for validating\narguments passed to mock objects. A gMock *matcher* is basically a predicate\nthat knows how to describe itself. It can be used in these assertion macros:\n\n\n\n| Fatal assertion | Nonfatal assertion | Verifies |\n| ------------------------------ | ------------------------------ | --------------------- |\n| `ASSERT_THAT(value, matcher);` | `EXPECT_THAT(value, matcher);` | value matches matcher |\n\n\n\nFor example, `StartsWith(prefix)` is a matcher that matches a string starting\nwith `prefix`, and you can write:\n\n```c++\nusing ::testing::StartsWith;\n...\n // Verifies that Foo() returns a string starting with \"Hello\".\n EXPECT_THAT(Foo(), StartsWith(\"Hello\"));\n```\n\nRead this\n[recipe](../../googlemock/docs/cook_book.md#using-matchers-in-googletest-assertions)\nin the gMock Cookbook for more details.\n\ngMock has a rich set of matchers. You can do many things googletest cannot do\nalone with them. For a list of matchers gMock provides, read\n[this](../../googlemock/docs/cook_book.md##using-matchers). It's easy to write\nyour [own matchers](../../googlemock/docs/cook_book.md#NewMatchers) too.\n\ngMock is bundled with googletest, so you don't need to add any build dependency\nin order to take advantage of this. Just include `\"testing/base/public/gmock.h\"`\nand you're ready to go.\n\n### More String Assertions\n\n(Please read the [previous](#asserting-using-gmock-matchers) section first if\nyou haven't.)\n\nYou can use the gMock\n[string matchers](../../googlemock/docs/cheat_sheet.md#string-matchers) with\n`EXPECT_THAT()` or `ASSERT_THAT()` to do more string comparison tricks\n(sub-string, prefix, suffix, regular expression, and etc). For example,\n\n```c++\nusing ::testing::HasSubstr;\nusing ::testing::MatchesRegex;\n...\n ASSERT_THAT(foo_string, HasSubstr(\"needle\"));\n EXPECT_THAT(bar_string, MatchesRegex(\"\\\\w*\\\\d+\"));\n```\n\nIf the string contains a well-formed HTML or XML document, you can check whether\nits DOM tree matches an\n[XPath expression](http://www.w3.org/TR/xpath/#contents):\n\n```c++\n// Currently still in //template/prototemplate/testing:xpath_matcher\n#include \"template/prototemplate/testing/xpath_matcher.h\"\nusing prototemplate::testing::MatchesXPath;\nEXPECT_THAT(html_string, MatchesXPath(\"//a[text()='click here']\"));\n```\n\n### Windows HRESULT assertions\n\nThese assertions test for `HRESULT` success or failure.\n\nFatal assertion | Nonfatal assertion | Verifies\n-------------------------------------- | -------------------------------------- | --------\n`ASSERT_HRESULT_SUCCEEDED(expression)` | `EXPECT_HRESULT_SUCCEEDED(expression)` | `expression` is a success `HRESULT`\n`ASSERT_HRESULT_FAILED(expression)` | `EXPECT_HRESULT_FAILED(expression)` | `expression` is a failure `HRESULT`\n\nThe generated output contains the human-readable error message associated with\nthe `HRESULT` code returned by `expression`.\n\nYou might use them like this:\n\n```c++\nCComPtr shell;\nASSERT_HRESULT_SUCCEEDED(shell.CoCreateInstance(L\"Shell.Application\"));\nCComVariant empty;\nASSERT_HRESULT_SUCCEEDED(shell->ShellExecute(CComBSTR(url), empty, empty, empty, empty));\n```\n\n### Type Assertions\n\nYou can call the function\n\n```c++\n::testing::StaticAssertTypeEq();\n```\n\nto assert that types `T1` and `T2` are the same. The function does nothing if\nthe assertion is satisfied. If the types are different, the function call will\nfail to compile, the compiler error message will say that\n`T1 and T2 are not the same type` and most likely (depending on the compiler)\nshow you the actual values of `T1` and `T2`. This is mainly useful inside\ntemplate code.\n\n**Caveat**: When used inside a member function of a class template or a function\ntemplate, `StaticAssertTypeEq()` is effective only if the function is\ninstantiated. For example, given:\n\n```c++\ntemplate class Foo {\n public:\n void Bar() { ::testing::StaticAssertTypeEq(); }\n};\n```\n\nthe code:\n\n```c++\nvoid Test1() { Foo foo; }\n```\n\nwill not generate a compiler error, as `Foo::Bar()` is never actually\ninstantiated. Instead, you need:\n\n```c++\nvoid Test2() { Foo foo; foo.Bar(); }\n```\n\nto cause a compiler error.\n\n### Assertion Placement\n\nYou can use assertions in any C++ function. In particular, it doesn't have to be\na method of the test fixture class. The one constraint is that assertions that\ngenerate a fatal failure (`FAIL*` and `ASSERT_*`) can only be used in\nvoid-returning functions. This is a consequence of Google's not using\nexceptions. By placing it in a non-void function you'll get a confusing compile\nerror like `\"error: void value not ignored as it ought to be\"` or `\"cannot\ninitialize return object of type 'bool' with an rvalue of type 'void'\"` or\n`\"error: no viable conversion from 'void' to 'string'\"`.\n\nIf you need to use fatal assertions in a function that returns non-void, one\noption is to make the function return the value in an out parameter instead. For\nexample, you can rewrite `T2 Foo(T1 x)` to `void Foo(T1 x, T2* result)`. You\nneed to make sure that `*result` contains some sensible value even when the\nfunction returns prematurely. As the function now returns `void`, you can use\nany assertion inside of it.\n\nIf changing the function's type is not an option, you should just use assertions\nthat generate non-fatal failures, such as `ADD_FAILURE*` and `EXPECT_*`.\n\nNOTE: Constructors and destructors are not considered void-returning functions,\naccording to the C++ language specification, and so you may not use fatal\nassertions in them; you'll get a compilation error if you try. Instead, either\ncall `abort` and crash the entire test executable, or put the fatal assertion in\na `SetUp`/`TearDown` function; see\n[constructor/destructor vs. `SetUp`/`TearDown`](faq.md#CtorVsSetUp)\n\nWARNING: A fatal assertion in a helper function (private void-returning method)\ncalled from a constructor or destructor does not does not terminate the current\ntest, as your intuition might suggest: it merely returns from the constructor or\ndestructor early, possibly leaving your object in a partially-constructed or\npartially-destructed state! You almost certainly want to `abort` or use\n`SetUp`/`TearDown` instead.\n\n## Teaching googletest How to Print Your Values\n\nWhen a test assertion such as `EXPECT_EQ` fails, googletest prints the argument\nvalues to help you debug. It does this using a user-extensible value printer.\n\nThis printer knows how to print built-in C++ types, native arrays, STL\ncontainers, and any type that supports the `<<` operator. For other types, it\nprints the raw bytes in the value and hopes that you the user can figure it out.\n\nAs mentioned earlier, the printer is *extensible*. That means you can teach it\nto do a better job at printing your particular type than to dump the bytes. To\ndo that, define `<<` for your type:\n\n```c++\n#include \n\nnamespace foo {\n\nclass Bar { // We want googletest to be able to print instances of this.\n...\n // Create a free inline friend function.\n friend std::ostream& operator<<(std::ostream& os, const Bar& bar) {\n return os << bar.DebugString(); // whatever needed to print bar to os\n }\n};\n\n// If you can't declare the function in the class it's important that the\n// << operator is defined in the SAME namespace that defines Bar. C++'s look-up\n// rules rely on that.\nstd::ostream& operator<<(std::ostream& os, const Bar& bar) {\n return os << bar.DebugString(); // whatever needed to print bar to os\n}\n\n} // namespace foo\n```\n\nSometimes, this might not be an option: your team may consider it bad style to\nhave a `<<` operator for `Bar`, or `Bar` may already have a `<<` operator that\ndoesn't do what you want (and you cannot change it). If so, you can instead\ndefine a `PrintTo()` function like this:\n\n```c++\n#include \n\nnamespace foo {\n\nclass Bar {\n ...\n friend void PrintTo(const Bar& bar, std::ostream* os) {\n *os << bar.DebugString(); // whatever needed to print bar to os\n }\n};\n\n// If you can't declare the function in the class it's important that PrintTo()\n// is defined in the SAME namespace that defines Bar. C++'s look-up rules rely\n// on that.\nvoid PrintTo(const Bar& bar, std::ostream* os) {\n *os << bar.DebugString(); // whatever needed to print bar to os\n}\n\n} // namespace foo\n```\n\nIf you have defined both `<<` and `PrintTo()`, the latter will be used when\ngoogletest is concerned. This allows you to customize how the value appears in\ngoogletest's output without affecting code that relies on the behavior of its\n`<<` operator.\n\nIf you want to print a value `x` using googletest's value printer yourself, just\ncall `::testing::PrintToString(x)`, which returns an `std::string`:\n\n```c++\nvector > bar_ints = GetBarIntVector();\n\nEXPECT_TRUE(IsCorrectBarIntVector(bar_ints))\n << \"bar_ints = \" << ::testing::PrintToString(bar_ints);\n```\n\n## Death Tests\n\nIn many applications, there are assertions that can cause application failure if\na condition is not met. These sanity checks, which ensure that the program is in\na known good state, are there to fail at the earliest possible time after some\nprogram state is corrupted. If the assertion checks the wrong condition, then\nthe program may proceed in an erroneous state, which could lead to memory\ncorruption, security holes, or worse. Hence it is vitally important to test that\nsuch assertion statements work as expected.\n\nSince these precondition checks cause the processes to die, we call such tests\n_death tests_. More generally, any test that checks that a program terminates\n(except by throwing an exception) in an expected fashion is also a death test.\n\nNote that if a piece of code throws an exception, we don't consider it \"death\"\nfor the purpose of death tests, as the caller of the code could catch the\nexception and avoid the crash. If you want to verify exceptions thrown by your\ncode, see [Exception Assertions](#ExceptionAssertions).\n\nIf you want to test `EXPECT_*()/ASSERT_*()` failures in your test code, see\nCatching Failures\n\n### How to Write a Death Test\n\ngoogletest has the following macros to support death tests:\n\nFatal assertion | Nonfatal assertion | Verifies\n------------------------------------------------ | ------------------------------------------------ | --------\n`ASSERT_DEATH(statement, matcher);` | `EXPECT_DEATH(statement, matcher);` | `statement` crashes with the given error\n`ASSERT_DEATH_IF_SUPPORTED(statement, matcher);` | `EXPECT_DEATH_IF_SUPPORTED(statement, matcher);` | if death tests are supported, verifies that `statement` crashes with the given error; otherwise verifies nothing\n`ASSERT_EXIT(statement, predicate, matcher);` | `EXPECT_EXIT(statement, predicate, matcher);` | `statement` exits with the given error, and its exit code matches `predicate`\n\nwhere `statement` is a statement that is expected to cause the process to die,\n`predicate` is a function or function object that evaluates an integer exit\nstatus, and `matcher` is either a gMock matcher matching a `const std::string&`\nor a (Perl) regular expression - either of which is matched against the stderr\noutput of `statement`. For legacy reasons, a bare string (i.e. with no matcher)\nis interpreted as `ContainsRegex(str)`, **not** `Eq(str)`. Note that `statement`\ncan be *any valid statement* (including *compound statement*) and doesn't have\nto be an expression.\n\nAs usual, the `ASSERT` variants abort the current test function, while the\n`EXPECT` variants do not.\n\n> NOTE: We use the word \"crash\" here to mean that the process terminates with a\n> *non-zero* exit status code. There are two possibilities: either the process\n> has called `exit()` or `_exit()` with a non-zero value, or it may be killed by\n> a signal.\n>\n> This means that if *`statement`* terminates the process with a 0 exit code, it\n> is *not* considered a crash by `EXPECT_DEATH`. Use `EXPECT_EXIT` instead if\n> this is the case, or if you want to restrict the exit code more precisely.\n\nA predicate here must accept an `int` and return a `bool`. The death test\nsucceeds only if the predicate returns `true`. googletest defines a few\npredicates that handle the most common cases:\n\n```c++\n::testing::ExitedWithCode(exit_code)\n```\n\nThis expression is `true` if the program exited normally with the given exit\ncode.\n\n```c++\n::testing::KilledBySignal(signal_number) // Not available on Windows.\n```\n\nThis expression is `true` if the program was killed by the given signal.\n\nThe `*_DEATH` macros are convenient wrappers for `*_EXIT` that use a predicate\nthat verifies the process' exit code is non-zero.\n\nNote that a death test only cares about three things:\n\n1. does `statement` abort or exit the process?\n2. (in the case of `ASSERT_EXIT` and `EXPECT_EXIT`) does the exit status\n satisfy `predicate`? Or (in the case of `ASSERT_DEATH` and `EXPECT_DEATH`)\n is the exit status non-zero? And\n3. does the stderr output match `matcher`?\n\nIn particular, if `statement` generates an `ASSERT_*` or `EXPECT_*` failure, it\nwill **not** cause the death test to fail, as googletest assertions don't abort\nthe process.\n\nTo write a death test, simply use one of the above macros inside your test\nfunction. For example,\n\n```c++\nTEST(MyDeathTest, Foo) {\n // This death test uses a compound statement.\n ASSERT_DEATH({\n int n = 5;\n Foo(&n);\n }, \"Error on line .* of Foo()\");\n}\n\nTEST(MyDeathTest, NormalExit) {\n EXPECT_EXIT(NormalExit(), ::testing::ExitedWithCode(0), \"Success\");\n}\n\nTEST(MyDeathTest, KillMyself) {\n EXPECT_EXIT(KillMyself(), ::testing::KilledBySignal(SIGKILL),\n \"Sending myself unblockable signal\");\n}\n```\n\nverifies that:\n\n* calling `Foo(5)` causes the process to die with the given error message,\n* calling `NormalExit()` causes the process to print `\"Success\"` to stderr and\n exit with exit code 0, and\n* calling `KillMyself()` kills the process with signal `SIGKILL`.\n\nThe test function body may contain other assertions and statements as well, if\nnecessary.\n\n### Death Test Naming\n\nIMPORTANT: We strongly recommend you to follow the convention of naming your\n**test suite** (not test) `*DeathTest` when it contains a death test, as\ndemonstrated in the above example. The\n[Death Tests And Threads](#death-tests-and-threads) section below explains why.\n\nIf a test fixture class is shared by normal tests and death tests, you can use\n`using` or `typedef` to introduce an alias for the fixture class and avoid\nduplicating its code:\n\n```c++\nclass FooTest : public ::testing::Test { ... };\n\nusing FooDeathTest = FooTest;\n\nTEST_F(FooTest, DoesThis) {\n // normal test\n}\n\nTEST_F(FooDeathTest, DoesThat) {\n // death test\n}\n```\n\n### Regular Expression Syntax\n\nOn POSIX systems (e.g. Linux, Cygwin, and Mac), googletest uses the\n[POSIX extended regular expression](http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_04)\nsyntax. To learn about this syntax, you may want to read this\n[Wikipedia entry](http://en.wikipedia.org/wiki/Regular_expression#POSIX_Extended_Regular_Expressions).\n\nOn Windows, googletest uses its own simple regular expression implementation. It\nlacks many features. For example, we don't support union (`\"x|y\"`), grouping\n(`\"(xy)\"`), brackets (`\"[xy]\"`), and repetition count (`\"x{5,7}\"`), among\nothers. Below is what we do support (`A` denotes a literal character, period\n(`.`), or a single `\\\\ ` escape sequence; `x` and `y` denote regular\nexpressions.):\n\nExpression | Meaning\n---------- | --------------------------------------------------------------\n`c` | matches any literal character `c`\n`\\\\d` | matches any decimal digit\n`\\\\D` | matches any character that's not a decimal digit\n`\\\\f` | matches `\\f`\n`\\\\n` | matches `\\n`\n`\\\\r` | matches `\\r`\n`\\\\s` | matches any ASCII whitespace, including `\\n`\n`\\\\S` | matches any character that's not a whitespace\n`\\\\t` | matches `\\t`\n`\\\\v` | matches `\\v`\n`\\\\w` | matches any letter, `_`, or decimal digit\n`\\\\W` | matches any character that `\\\\w` doesn't match\n`\\\\c` | matches any literal character `c`, which must be a punctuation\n`.` | matches any single character except `\\n`\n`A?` | matches 0 or 1 occurrences of `A`\n`A*` | matches 0 or many occurrences of `A`\n`A+` | matches 1 or many occurrences of `A`\n`^` | matches the beginning of a string (not that of each line)\n`$` | matches the end of a string (not that of each line)\n`xy` | matches `x` followed by `y`\n\nTo help you determine which capability is available on your system, googletest\ndefines macros to govern which regular expression it is using. The macros are:\n`GTEST_USES_SIMPLE_RE=1` or `GTEST_USES_POSIX_RE=1`. If you want your death\ntests to work in all cases, you can either `#if` on these macros or use the more\nlimited syntax only.\n\n### How It Works\n\nUnder the hood, `ASSERT_EXIT()` spawns a new process and executes the death test\nstatement in that process. The details of how precisely that happens depend on\nthe platform and the variable ::testing::GTEST_FLAG(death_test_style) (which is\ninitialized from the command-line flag `--gtest_death_test_style`).\n\n* On POSIX systems, `fork()` (or `clone()` on Linux) is used to spawn the\n child, after which:\n * If the variable's value is `\"fast\"`, the death test statement is\n immediately executed.\n * If the variable's value is `\"threadsafe\"`, the child process re-executes\n the unit test binary just as it was originally invoked, but with some\n extra flags to cause just the single death test under consideration to\n be run.\n* On Windows, the child is spawned using the `CreateProcess()` API, and\n re-executes the binary to cause just the single death test under\n consideration to be run - much like the `threadsafe` mode on POSIX.\n\nOther values for the variable are illegal and will cause the death test to fail.\nCurrently, the flag's default value is **\"fast\"**\n\n1. the child's exit status satisfies the predicate, and\n2. the child's stderr matches the regular expression.\n\nIf the death test statement runs to completion without dying, the child process\nwill nonetheless terminate, and the assertion fails.\n\n### Death Tests And Threads\n\nThe reason for the two death test styles has to do with thread safety. Due to\nwell-known problems with forking in the presence of threads, death tests should\nbe run in a single-threaded context. Sometimes, however, it isn't feasible to\narrange that kind of environment. For example, statically-initialized modules\nmay start threads before main is ever reached. Once threads have been created,\nit may be difficult or impossible to clean them up.\n\ngoogletest has three features intended to raise awareness of threading issues.\n\n1. A warning is emitted if multiple threads are running when a death test is\n encountered.\n2. Test suites with a name ending in \"DeathTest\" are run before all other\n tests.\n3. It uses `clone()` instead of `fork()` to spawn the child process on Linux\n (`clone()` is not available on Cygwin and Mac), as `fork()` is more likely\n to cause the child to hang when the parent process has multiple threads.\n\nIt's perfectly fine to create threads inside a death test statement; they are\nexecuted in a separate process and cannot affect the parent.\n\n### Death Test Styles\n\nThe \"threadsafe\" death test style was introduced in order to help mitigate the\nrisks of testing in a possibly multithreaded environment. It trades increased\ntest execution time (potentially dramatically so) for improved thread safety.\n\nThe automated testing framework does not set the style flag. You can choose a\nparticular style of death tests by setting the flag programmatically:\n\n```c++\ntesting::FLAGS_gtest_death_test_style=\"threadsafe\"\n```\n\nYou can do this in `main()` to set the style for all death tests in the binary,\nor in individual tests. Recall that flags are saved before running each test and\nrestored afterwards, so you need not do that yourself. For example:\n\n```c++\nint main(int argc, char** argv) {\n InitGoogle(argv[0], &argc, &argv, true);\n ::testing::FLAGS_gtest_death_test_style = \"fast\";\n return RUN_ALL_TESTS();\n}\n\nTEST(MyDeathTest, TestOne) {\n ::testing::FLAGS_gtest_death_test_style = \"threadsafe\";\n // This test is run in the \"threadsafe\" style:\n ASSERT_DEATH(ThisShouldDie(), \"\");\n}\n\nTEST(MyDeathTest, TestTwo) {\n // This test is run in the \"fast\" style:\n ASSERT_DEATH(ThisShouldDie(), \"\");\n}\n```\n\n### Caveats\n\nThe `statement` argument of `ASSERT_EXIT()` can be any valid C++ statement. If\nit leaves the current function via a `return` statement or by throwing an\nexception, the death test is considered to have failed. Some googletest macros\nmay return from the current function (e.g. `ASSERT_TRUE()`), so be sure to avoid\nthem in `statement`.\n\nSince `statement` runs in the child process, any in-memory side effect (e.g.\nmodifying a variable, releasing memory, etc) it causes will *not* be observable\nin the parent process. In particular, if you release memory in a death test,\nyour program will fail the heap check as the parent process will never see the\nmemory reclaimed. To solve this problem, you can\n\n1. try not to free memory in a death test;\n2. free the memory again in the parent process; or\n3. do not use the heap checker in your program.\n\nDue to an implementation detail, you cannot place multiple death test assertions\non the same line; otherwise, compilation will fail with an unobvious error\nmessage.\n\nDespite the improved thread safety afforded by the \"threadsafe\" style of death\ntest, thread problems such as deadlock are still possible in the presence of\nhandlers registered with `pthread_atfork(3)`.\n\n\n## Using Assertions in Sub-routines\n\n### Adding Traces to Assertions\n\nIf a test sub-routine is called from several places, when an assertion inside it\nfails, it can be hard to tell which invocation of the sub-routine the failure is\nfrom. You can alleviate this problem using extra logging or custom failure\nmessages, but that usually clutters up your tests. A better solution is to use\nthe `SCOPED_TRACE` macro or the `ScopedTrace` utility:\n\n```c++\nSCOPED_TRACE(message);\n```\n```c++\nScopedTrace trace(\"file_path\", line_number, message);\n```\n\nwhere `message` can be anything streamable to `std::ostream`. `SCOPED_TRACE`\nmacro will cause the current file name, line number, and the given message to be\nadded in every failure message. `ScopedTrace` accepts explicit file name and\nline number in arguments, which is useful for writing test helpers. The effect\nwill be undone when the control leaves the current lexical scope.\n\nFor example,\n\n```c++\n10: void Sub1(int n) {\n11: EXPECT_EQ(Bar(n), 1);\n12: EXPECT_EQ(Bar(n + 1), 2);\n13: }\n14:\n15: TEST(FooTest, Bar) {\n16: {\n17: SCOPED_TRACE(\"A\"); // This trace point will be included in\n18: // every failure in this scope.\n19: Sub1(1);\n20: }\n21: // Now it won't.\n22: Sub1(9);\n23: }\n```\n\ncould result in messages like these:\n\n```none\npath/to/foo_test.cc:11: Failure\nValue of: Bar(n)\nExpected: 1\n Actual: 2\n Trace:\npath/to/foo_test.cc:17: A\n\npath/to/foo_test.cc:12: Failure\nValue of: Bar(n + 1)\nExpected: 2\n Actual: 3\n```\n\nWithout the trace, it would've been difficult to know which invocation of\n`Sub1()` the two failures come from respectively. (You could add an extra\nmessage to each assertion in `Sub1()` to indicate the value of `n`, but that's\ntedious.)\n\nSome tips on using `SCOPED_TRACE`:\n\n1. With a suitable message, it's often enough to use `SCOPED_TRACE` at the\n beginning of a sub-routine, instead of at each call site.\n2. When calling sub-routines inside a loop, make the loop iterator part of the\n message in `SCOPED_TRACE` such that you can know which iteration the failure\n is from.\n3. Sometimes the line number of the trace point is enough for identifying the\n particular invocation of a sub-routine. In this case, you don't have to\n choose a unique message for `SCOPED_TRACE`. You can simply use `\"\"`.\n4. You can use `SCOPED_TRACE` in an inner scope when there is one in the outer\n scope. In this case, all active trace points will be included in the failure\n messages, in reverse order they are encountered.\n5. The trace dump is clickable in Emacs - hit `return` on a line number and\n you'll be taken to that line in the source file!\n\n### Propagating Fatal Failures\n\nA common pitfall when using `ASSERT_*` and `FAIL*` is not understanding that\nwhen they fail they only abort the _current function_, not the entire test. For\nexample, the following test will segfault:\n\n```c++\nvoid Subroutine() {\n // Generates a fatal failure and aborts the current function.\n ASSERT_EQ(1, 2);\n\n // The following won't be executed.\n ...\n}\n\nTEST(FooTest, Bar) {\n Subroutine(); // The intended behavior is for the fatal failure\n // in Subroutine() to abort the entire test.\n\n // The actual behavior: the function goes on after Subroutine() returns.\n int* p = NULL;\n *p = 3; // Segfault!\n}\n```\n\nTo alleviate this, googletest provides three different solutions. You could use\neither exceptions, the `(ASSERT|EXPECT)_NO_FATAL_FAILURE` assertions or the\n`HasFatalFailure()` function. They are described in the following two\nsubsections.\n\n#### Asserting on Subroutines with an exception\n\nThe following code can turn ASSERT-failure into an exception:\n\n```c++\nclass ThrowListener : public testing::EmptyTestEventListener {\n void OnTestPartResult(const testing::TestPartResult& result) override {\n if (result.type() == testing::TestPartResult::kFatalFailure) {\n throw testing::AssertionException(result);\n }\n }\n};\nint main(int argc, char** argv) {\n ...\n testing::UnitTest::GetInstance()->listeners().Append(new ThrowListener);\n return RUN_ALL_TESTS();\n}\n```\n\nThis listener should be added after other listeners if you have any, otherwise\nthey won't see failed `OnTestPartResult`.\n\n#### Asserting on Subroutines\n\nAs shown above, if your test calls a subroutine that has an `ASSERT_*` failure\nin it, the test will continue after the subroutine returns. This may not be what\nyou want.\n\nOften people want fatal failures to propagate like exceptions. For that\ngoogletest offers the following macros:\n\nFatal assertion | Nonfatal assertion | Verifies\n------------------------------------- | ------------------------------------- | --------\n`ASSERT_NO_FATAL_FAILURE(statement);` | `EXPECT_NO_FATAL_FAILURE(statement);` | `statement` doesn't generate any new fatal failures in the current thread.\n\nOnly failures in the thread that executes the assertion are checked to determine\nthe result of this type of assertions. If `statement` creates new threads,\nfailures in these threads are ignored.\n\nExamples:\n\n```c++\nASSERT_NO_FATAL_FAILURE(Foo());\n\nint i;\nEXPECT_NO_FATAL_FAILURE({\n i = Bar();\n});\n```\n\nAssertions from multiple threads are currently not supported on Windows.\n\n#### Checking for Failures in the Current Test\n\n`HasFatalFailure()` in the `::testing::Test` class returns `true` if an\nassertion in the current test has suffered a fatal failure. This allows\nfunctions to catch fatal failures in a sub-routine and return early.\n\n```c++\nclass Test {\n public:\n ...\n static bool HasFatalFailure();\n};\n```\n\nThe typical usage, which basically simulates the behavior of a thrown exception,\nis:\n\n```c++\nTEST(FooTest, Bar) {\n Subroutine();\n // Aborts if Subroutine() had a fatal failure.\n if (HasFatalFailure()) return;\n\n // The following won't be executed.\n ...\n}\n```\n\nIf `HasFatalFailure()` is used outside of `TEST()` , `TEST_F()` , or a test\nfixture, you must add the `::testing::Test::` prefix, as in:\n\n```c++\nif (::testing::Test::HasFatalFailure()) return;\n```\n\nSimilarly, `HasNonfatalFailure()` returns `true` if the current test has at\nleast one non-fatal failure, and `HasFailure()` returns `true` if the current\ntest has at least one failure of either kind.\n\n## Logging Additional Information\n\nIn your test code, you can call `RecordProperty(\"key\", value)` to log additional\ninformation, where `value` can be either a string or an `int`. The *last* value\nrecorded for a key will be emitted to the\n[XML output](#generating-an-xml-report) if you specify one. For example, the\ntest\n\n```c++\nTEST_F(WidgetUsageTest, MinAndMaxWidgets) {\n RecordProperty(\"MaximumWidgets\", ComputeMaxUsage());\n RecordProperty(\"MinimumWidgets\", ComputeMinUsage());\n}\n```\n\nwill output XML like this:\n\n```xml\n ...\n \n ...\n```\n\n> NOTE:\n>\n> * `RecordProperty()` is a static member of the `Test` class. Therefore it\n> needs to be prefixed with `::testing::Test::` if used outside of the\n> `TEST` body and the test fixture class.\n> * *`key`* must be a valid XML attribute name, and cannot conflict with the\n> ones already used by googletest (`name`, `status`, `time`, `classname`,\n> `type_param`, and `value_param`).\n> * Calling `RecordProperty()` outside of the lifespan of a test is allowed.\n> If it's called outside of a test but between a test suite's\n> `SetUpTestSuite()` and `TearDownTestSuite()` methods, it will be\n> attributed to the XML element for the test suite. If it's called outside\n> of all test suites (e.g. in a test environment), it will be attributed to\n> the top-level XML element.\n\n## Sharing Resources Between Tests in the Same Test Suite\n\ngoogletest creates a new test fixture object for each test in order to make\ntests independent and easier to debug. However, sometimes tests use resources\nthat are expensive to set up, making the one-copy-per-test model prohibitively\nexpensive.\n\nIf the tests don't change the resource, there's no harm in their sharing a\nsingle resource copy. So, in addition to per-test set-up/tear-down, googletest\nalso supports per-test-suite set-up/tear-down. To use it:\n\n1. In your test fixture class (say `FooTest` ), declare as `static` some member\n variables to hold the shared resources.\n2. Outside your test fixture class (typically just below it), define those\n member variables, optionally giving them initial values.\n3. In the same test fixture class, define a `static void SetUpTestSuite()`\n function (remember not to spell it as **`SetupTestSuite`** with a small\n `u`!) to set up the shared resources and a `static void TearDownTestSuite()`\n function to tear them down.\n\nThat's it! googletest automatically calls `SetUpTestSuite()` before running the\n*first test* in the `FooTest` test suite (i.e. before creating the first\n`FooTest` object), and calls `TearDownTestSuite()` after running the *last test*\nin it (i.e. after deleting the last `FooTest` object). In between, the tests can\nuse the shared resources.\n\nRemember that the test order is undefined, so your code can't depend on a test\npreceding or following another. Also, the tests must either not modify the state\nof any shared resource, or, if they do modify the state, they must restore the\nstate to its original value before passing control to the next test.\n\nHere's an example of per-test-suite set-up and tear-down:\n\n```c++\nclass FooTest : public ::testing::Test {\n protected:\n // Per-test-suite set-up.\n // Called before the first test in this test suite.\n // Can be omitted if not needed.\n static void SetUpTestSuite() {\n shared_resource_ = new ...;\n }\n\n // Per-test-suite tear-down.\n // Called after the last test in this test suite.\n // Can be omitted if not needed.\n static void TearDownTestSuite() {\n delete shared_resource_;\n shared_resource_ = NULL;\n }\n\n // You can define per-test set-up logic as usual.\n virtual void SetUp() { ... }\n\n // You can define per-test tear-down logic as usual.\n virtual void TearDown() { ... }\n\n // Some expensive resource shared by all tests.\n static T* shared_resource_;\n};\n\nT* FooTest::shared_resource_ = NULL;\n\nTEST_F(FooTest, Test1) {\n ... you can refer to shared_resource_ here ...\n}\n\nTEST_F(FooTest, Test2) {\n ... you can refer to shared_resource_ here ...\n}\n```\n\nNOTE: Though the above code declares `SetUpTestSuite()` protected, it may\nsometimes be necessary to declare it public, such as when using it with\n`TEST_P`.\n\n## Global Set-Up and Tear-Down\n\nJust as you can do set-up and tear-down at the test level and the test suite\nlevel, you can also do it at the test program level. Here's how.\n\nFirst, you subclass the `::testing::Environment` class to define a test\nenvironment, which knows how to set-up and tear-down:\n\n```c++\nclass Environment : public ::testing::Environment {\n public:\n virtual ~Environment() {}\n\n // Override this to define how to set up the environment.\n void SetUp() override {}\n\n // Override this to define how to tear down the environment.\n void TearDown() override {}\n};\n```\n\nThen, you register an instance of your environment class with googletest by\ncalling the `::testing::AddGlobalTestEnvironment()` function:\n\n```c++\nEnvironment* AddGlobalTestEnvironment(Environment* env);\n```\n\nNow, when `RUN_ALL_TESTS()` is called, it first calls the `SetUp()` method of\neach environment object, then runs the tests if none of the environments\nreported fatal failures and `GTEST_SKIP()` was not called. `RUN_ALL_TESTS()`\nalways calls `TearDown()` with each environment object, regardless of whether or\nnot the tests were run.\n\nIt's OK to register multiple environment objects. In this suite, their `SetUp()`\nwill be called in the order they are registered, and their `TearDown()` will be\ncalled in the reverse order.\n\nNote that googletest takes ownership of the registered environment objects.\nTherefore **do not delete them** by yourself.\n\nYou should call `AddGlobalTestEnvironment()` before `RUN_ALL_TESTS()` is called,\nprobably in `main()`. If you use `gtest_main`, you need to call this before\n`main()` starts for it to take effect. One way to do this is to define a global\nvariable like this:\n\n```c++\n::testing::Environment* const foo_env =\n ::testing::AddGlobalTestEnvironment(new FooEnvironment);\n```\n\nHowever, we strongly recommend you to write your own `main()` and call\n`AddGlobalTestEnvironment()` there, as relying on initialization of global\nvariables makes the code harder to read and may cause problems when you register\nmultiple environments from different translation units and the environments have\ndependencies among them (remember that the compiler doesn't guarantee the order\nin which global variables from different translation units are initialized).\n\n## Value-Parameterized Tests\n\n*Value-parameterized tests* allow you to test your code with different\nparameters without writing multiple copies of the same test. This is useful in a\nnumber of situations, for example:\n\n* You have a piece of code whose behavior is affected by one or more\n command-line flags. You want to make sure your code performs correctly for\n various values of those flags.\n* You want to test different implementations of an OO interface.\n* You want to test your code over various inputs (a.k.a. data-driven testing).\n This feature is easy to abuse, so please exercise your good sense when doing\n it!\n\n### How to Write Value-Parameterized Tests\n\nTo write value-parameterized tests, first you should define a fixture class. It\nmust be derived from both `testing::Test` and `testing::WithParamInterface`\n(the latter is a pure interface), where `T` is the type of your parameter\nvalues. For convenience, you can just derive the fixture class from\n`testing::TestWithParam`, which itself is derived from both `testing::Test`\nand `testing::WithParamInterface`. `T` can be any copyable type. If it's a\nraw pointer, you are responsible for managing the lifespan of the pointed\nvalues.\n\nNOTE: If your test fixture defines `SetUpTestSuite()` or `TearDownTestSuite()`\nthey must be declared **public** rather than **protected** in order to use\n`TEST_P`.\n\n```c++\nclass FooTest :\n public testing::TestWithParam {\n // You can implement all the usual fixture class members here.\n // To access the test parameter, call GetParam() from class\n // TestWithParam.\n};\n\n// Or, when you want to add parameters to a pre-existing fixture class:\nclass BaseTest : public testing::Test {\n ...\n};\nclass BarTest : public BaseTest,\n public testing::WithParamInterface {\n ...\n};\n```\n\nThen, use the `TEST_P` macro to define as many test patterns using this fixture\nas you want. The `_P` suffix is for \"parameterized\" or \"pattern\", whichever you\nprefer to think.\n\n```c++\nTEST_P(FooTest, DoesBlah) {\n // Inside a test, access the test parameter with the GetParam() method\n // of the TestWithParam class:\n EXPECT_TRUE(foo.Blah(GetParam()));\n ...\n}\n\nTEST_P(FooTest, HasBlahBlah) {\n ...\n}\n```\n\nFinally, you can use `INSTANTIATE_TEST_SUITE_P` to instantiate the test suite\nwith any set of parameters you want. googletest defines a number of functions\nfor generating test parameters. They return what we call (surprise!) *parameter\ngenerators*. Here is a summary of them, which are all in the `testing`\nnamespace:\n\n\n\n| Parameter Generator | Behavior |\n| ----------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------- |\n| `Range(begin, end [, step])` | Yields values `{begin, begin+step, begin+step+step, ...}`. The values do not include `end`. `step` defaults to 1. |\n| `Values(v1, v2, ..., vN)` | Yields values `{v1, v2, ..., vN}`. |\n| `ValuesIn(container)` and `ValuesIn(begin,end)` | Yields values from a C-style array, an STL-style container, or an iterator range `[begin, end)` |\n| `Bool()` | Yields sequence `{false, true}`. |\n| `Combine(g1, g2, ..., gN)` | Yields all combinations (Cartesian product) as std\\:\\:tuples of the values generated by the `N` generators. |\n\n\n\nFor more details, see the comments at the definitions of these functions.\n\nThe following statement will instantiate tests from the `FooTest` test suite\neach with parameter values `\"meeny\"`, `\"miny\"`, and `\"moe\"`.\n\n```c++\nINSTANTIATE_TEST_SUITE_P(InstantiationName,\n FooTest,\n testing::Values(\"meeny\", \"miny\", \"moe\"));\n```\n\nNOTE: The code above must be placed at global or namespace scope, not at\nfunction scope.\n\nNOTE: Don't forget this step! If you do your test will silently pass, but none\nof its suites will ever run!\n\nTo distinguish different instances of the pattern (yes, you can instantiate it\nmore than once), the first argument to `INSTANTIATE_TEST_SUITE_P` is a prefix\nthat will be added to the actual test suite name. Remember to pick unique\nprefixes for different instantiations. The tests from the instantiation above\nwill have these names:\n\n* `InstantiationName/FooTest.DoesBlah/0` for `\"meeny\"`\n* `InstantiationName/FooTest.DoesBlah/1` for `\"miny\"`\n* `InstantiationName/FooTest.DoesBlah/2` for `\"moe\"`\n* `InstantiationName/FooTest.HasBlahBlah/0` for `\"meeny\"`\n* `InstantiationName/FooTest.HasBlahBlah/1` for `\"miny\"`\n* `InstantiationName/FooTest.HasBlahBlah/2` for `\"moe\"`\n\nYou can use these names in [`--gtest_filter`](#running-a-subset-of-the-tests).\n\nThis statement will instantiate all tests from `FooTest` again, each with\nparameter values `\"cat\"` and `\"dog\"`:\n\n```c++\nconst char* pets[] = {\"cat\", \"dog\"};\nINSTANTIATE_TEST_SUITE_P(AnotherInstantiationName, FooTest,\n testing::ValuesIn(pets));\n```\n\nThe tests from the instantiation above will have these names:\n\n* `AnotherInstantiationName/FooTest.DoesBlah/0` for `\"cat\"`\n* `AnotherInstantiationName/FooTest.DoesBlah/1` for `\"dog\"`\n* `AnotherInstantiationName/FooTest.HasBlahBlah/0` for `\"cat\"`\n* `AnotherInstantiationName/FooTest.HasBlahBlah/1` for `\"dog\"`\n\nPlease note that `INSTANTIATE_TEST_SUITE_P` will instantiate *all* tests in the\ngiven test suite, whether their definitions come before or *after* the\n`INSTANTIATE_TEST_SUITE_P` statement.\n\nYou can see [sample7_unittest.cc] and [sample8_unittest.cc] for more examples.\n\n[sample7_unittest.cc]: ../samples/sample7_unittest.cc \"Parameterized Test example\"\n[sample8_unittest.cc]: ../samples/sample8_unittest.cc \"Parameterized Test example with multiple parameters\"\n\n### Creating Value-Parameterized Abstract Tests\n\nIn the above, we define and instantiate `FooTest` in the *same* source file.\nSometimes you may want to define value-parameterized tests in a library and let\nother people instantiate them later. This pattern is known as *abstract tests*.\nAs an example of its application, when you are designing an interface you can\nwrite a standard suite of abstract tests (perhaps using a factory function as\nthe test parameter) that all implementations of the interface are expected to\npass. When someone implements the interface, they can instantiate your suite to\nget all the interface-conformance tests for free.\n\nTo define abstract tests, you should organize your code like this:\n\n1. Put the definition of the parameterized test fixture class (e.g. `FooTest`)\n in a header file, say `foo_param_test.h`. Think of this as *declaring* your\n abstract tests.\n2. Put the `TEST_P` definitions in `foo_param_test.cc`, which includes\n `foo_param_test.h`. Think of this as *implementing* your abstract tests.\n\nOnce they are defined, you can instantiate them by including `foo_param_test.h`,\ninvoking `INSTANTIATE_TEST_SUITE_P()`, and depending on the library target that\ncontains `foo_param_test.cc`. You can instantiate the same abstract test suite\nmultiple times, possibly in different source files.\n\n### Specifying Names for Value-Parameterized Test Parameters\n\nThe optional last argument to `INSTANTIATE_TEST_SUITE_P()` allows the user to\nspecify a function or functor that generates custom test name suffixes based on\nthe test parameters. The function should accept one argument of type\n`testing::TestParamInfo`, and return `std::string`.\n\n`testing::PrintToStringParamName` is a builtin test suffix generator that\nreturns the value of `testing::PrintToString(GetParam())`. It does not work for\n`std::string` or C strings.\n\nNOTE: test names must be non-empty, unique, and may only contain ASCII\nalphanumeric characters. In particular, they\n[should not contain underscores](faq.md#why-should-test-suite-names-and-test-names-not-contain-underscore)\n\n```c++\nclass MyTestSuite : public testing::TestWithParam {};\n\nTEST_P(MyTestSuite, MyTest)\n{\n std::cout << \"Example Test Param: \" << GetParam() << std::endl;\n}\n\nINSTANTIATE_TEST_SUITE_P(MyGroup, MyTestSuite, testing::Range(0, 10),\n testing::PrintToStringParamName());\n```\n\nProviding a custom functor allows for more control over test parameter name\ngeneration, especially for types where the automatic conversion does not\ngenerate helpful parameter names (e.g. strings as demonstrated above). The\nfollowing example illustrates this for multiple parameters, an enumeration type\nand a string, and also demonstrates how to combine generators. It uses a lambda\nfor conciseness:\n\n```c++\nenum class MyType { MY_FOO = 0, MY_BAR = 1 };\n\nclass MyTestSuite : public testing::TestWithParam> {\n};\n\nINSTANTIATE_TEST_SUITE_P(\n MyGroup, MyTestSuite,\n testing::Combine(\n testing::Values(MyType::VALUE_0, MyType::VALUE_1),\n testing::ValuesIn(\"\", \"\")),\n [](const testing::TestParamInfo& info) {\n string name = absl::StrCat(\n std::get<0>(info.param) == MY_FOO ? \"Foo\" : \"Bar\", \"_\",\n std::get<1>(info.param));\n absl::c_replace_if(name, [](char c) { return !std::isalnum(c); }, '_');\n return name;\n });\n```\n\n## Typed Tests\n\nSuppose you have multiple implementations of the same interface and want to make\nsure that all of them satisfy some common requirements. Or, you may have defined\nseveral types that are supposed to conform to the same \"concept\" and you want to\nverify it. In both cases, you want the same test logic repeated for different\ntypes.\n\nWhile you can write one `TEST` or `TEST_F` for each type you want to test (and\nyou may even factor the test logic into a function template that you invoke from\nthe `TEST`), it's tedious and doesn't scale: if you want `m` tests over `n`\ntypes, you'll end up writing `m*n` `TEST`s.\n\n*Typed tests* allow you to repeat the same test logic over a list of types. You\nonly need to write the test logic once, although you must know the type list\nwhen writing typed tests. Here's how you do it:\n\nFirst, define a fixture class template. It should be parameterized by a type.\nRemember to derive it from `::testing::Test`:\n\n```c++\ntemplate \nclass FooTest : public ::testing::Test {\n public:\n ...\n typedef std::list List;\n static T shared_;\n T value_;\n};\n```\n\nNext, associate a list of types with the test suite, which will be repeated for\neach type in the list:\n\n```c++\nusing MyTypes = ::testing::Types;\nTYPED_TEST_SUITE(FooTest, MyTypes);\n```\n\nThe type alias (`using` or `typedef`) is necessary for the `TYPED_TEST_SUITE`\nmacro to parse correctly. Otherwise the compiler will think that each comma in\nthe type list introduces a new macro argument.\n\nThen, use `TYPED_TEST()` instead of `TEST_F()` to define a typed test for this\ntest suite. You can repeat this as many times as you want:\n\n```c++\nTYPED_TEST(FooTest, DoesBlah) {\n // Inside a test, refer to the special name TypeParam to get the type\n // parameter. Since we are inside a derived class template, C++ requires\n // us to visit the members of FooTest via 'this'.\n TypeParam n = this->value_;\n\n // To visit static members of the fixture, add the 'TestFixture::'\n // prefix.\n n += TestFixture::shared_;\n\n // To refer to typedefs in the fixture, add the 'typename TestFixture::'\n // prefix. The 'typename' is required to satisfy the compiler.\n typename TestFixture::List values;\n\n values.push_back(n);\n ...\n}\n\nTYPED_TEST(FooTest, HasPropertyA) { ... }\n```\n\nYou can see [sample6_unittest.cc] for a complete example.\n\n[sample6_unittest.cc]: ../samples/sample6_unittest.cc \"Typed Test example\"\n\n## Type-Parameterized Tests\n\n*Type-parameterized tests* are like typed tests, except that they don't require\nyou to know the list of types ahead of time. Instead, you can define the test\nlogic first and instantiate it with different type lists later. You can even\ninstantiate it more than once in the same program.\n\nIf you are designing an interface or concept, you can define a suite of\ntype-parameterized tests to verify properties that any valid implementation of\nthe interface/concept should have. Then, the author of each implementation can\njust instantiate the test suite with their type to verify that it conforms to\nthe requirements, without having to write similar tests repeatedly. Here's an\nexample:\n\nFirst, define a fixture class template, as we did with typed tests:\n\n```c++\ntemplate \nclass FooTest : public ::testing::Test {\n ...\n};\n```\n\nNext, declare that you will define a type-parameterized test suite:\n\n```c++\nTYPED_TEST_SUITE_P(FooTest);\n```\n\nThen, use `TYPED_TEST_P()` to define a type-parameterized test. You can repeat\nthis as many times as you want:\n\n```c++\nTYPED_TEST_P(FooTest, DoesBlah) {\n // Inside a test, refer to TypeParam to get the type parameter.\n TypeParam n = 0;\n ...\n}\n\nTYPED_TEST_P(FooTest, HasPropertyA) { ... }\n```\n\nNow the tricky part: you need to register all test patterns using the\n`REGISTER_TYPED_TEST_SUITE_P` macro before you can instantiate them. The first\nargument of the macro is the test suite name; the rest are the names of the\ntests in this test suite:\n\n```c++\nREGISTER_TYPED_TEST_SUITE_P(FooTest,\n DoesBlah, HasPropertyA);\n```\n\nFinally, you are free to instantiate the pattern with the types you want. If you\nput the above code in a header file, you can `#include` it in multiple C++\nsource files and instantiate it multiple times.\n\n```c++\ntypedef ::testing::Types MyTypes;\nINSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, MyTypes);\n```\n\nTo distinguish different instances of the pattern, the first argument to the\n`INSTANTIATE_TYPED_TEST_SUITE_P` macro is a prefix that will be added to the\nactual test suite name. Remember to pick unique prefixes for different\ninstances.\n\nIn the special case where the type list contains only one type, you can write\nthat type directly without `::testing::Types<...>`, like this:\n\n```c++\nINSTANTIATE_TYPED_TEST_SUITE_P(My, FooTest, int);\n```\n\nYou can see [sample6_unittest.cc] for a complete example.\n\n## Testing Private Code\n\nIf you change your software's internal implementation, your tests should not\nbreak as long as the change is not observable by users. Therefore, **per the\nblack-box testing principle, most of the time you should test your code through\nits public interfaces.**\n\n**If you still find yourself needing to test internal implementation code,\nconsider if there's a better design.** The desire to test internal\nimplementation is often a sign that the class is doing too much. Consider\nextracting an implementation class, and testing it. Then use that implementation\nclass in the original class.\n\nIf you absolutely have to test non-public interface code though, you can. There\nare two cases to consider:\n\n* Static functions ( *not* the same as static member functions!) or unnamed\n namespaces, and\n* Private or protected class members\n\nTo test them, we use the following special techniques:\n\n* Both static functions and definitions/declarations in an unnamed namespace\n are only visible within the same translation unit. To test them, you can\n `#include` the entire `.cc` file being tested in your `*_test.cc` file.\n (#including `.cc` files is not a good way to reuse code - you should not do\n this in production code!)\n\n However, a better approach is to move the private code into the\n `foo::internal` namespace, where `foo` is the namespace your project\n normally uses, and put the private declarations in a `*-internal.h` file.\n Your production `.cc` files and your tests are allowed to include this\n internal header, but your clients are not. This way, you can fully test your\n internal implementation without leaking it to your clients.\n\n* Private class members are only accessible from within the class or by\n friends. To access a class' private members, you can declare your test\n fixture as a friend to the class and define accessors in your fixture. Tests\n using the fixture can then access the private members of your production\n class via the accessors in the fixture. Note that even though your fixture\n is a friend to your production class, your tests are not automatically\n friends to it, as they are technically defined in sub-classes of the\n fixture.\n\n Another way to test private members is to refactor them into an\n implementation class, which is then declared in a `*-internal.h` file. Your\n clients aren't allowed to include this header but your tests can. Such is\n called the\n [Pimpl](https://www.gamedev.net/articles/programming/general-and-gameplay-programming/the-c-pimpl-r1794/)\n (Private Implementation) idiom.\n\n Or, you can declare an individual test as a friend of your class by adding\n this line in the class body:\n\n ```c++\n FRIEND_TEST(TestSuiteName, TestName);\n ```\n\n For example,\n\n ```c++\n // foo.h\n class Foo {\n ...\n private:\n FRIEND_TEST(FooTest, BarReturnsZeroOnNull);\n\n int Bar(void* x);\n };\n\n // foo_test.cc\n ...\n TEST(FooTest, BarReturnsZeroOnNull) {\n Foo foo;\n EXPECT_EQ(foo.Bar(NULL), 0); // Uses Foo's private member Bar().\n }\n ```\n\n Pay special attention when your class is defined in a namespace, as you\n should define your test fixtures and tests in the same namespace if you want\n them to be friends of your class. For example, if the code to be tested\n looks like:\n\n ```c++\n namespace my_namespace {\n\n class Foo {\n friend class FooTest;\n FRIEND_TEST(FooTest, Bar);\n FRIEND_TEST(FooTest, Baz);\n ... definition of the class Foo ...\n };\n\n } // namespace my_namespace\n ```\n\n Your test code should be something like:\n\n ```c++\n namespace my_namespace {\n\n class FooTest : public ::testing::Test {\n protected:\n ...\n };\n\n TEST_F(FooTest, Bar) { ... }\n TEST_F(FooTest, Baz) { ... }\n\n } // namespace my_namespace\n ```\n\n## \"Catching\" Failures\n\nIf you are building a testing utility on top of googletest, you'll want to test\nyour utility. What framework would you use to test it? googletest, of course.\n\nThe challenge is to verify that your testing utility reports failures correctly.\nIn frameworks that report a failure by throwing an exception, you could catch\nthe exception and assert on it. But googletest doesn't use exceptions, so how do\nwe test that a piece of code generates an expected failure?\n\ngunit-spi.h contains some constructs to do this. After #including this header,\nyou can use\n\n```c++\n EXPECT_FATAL_FAILURE(statement, substring);\n```\n\nto assert that `statement` generates a fatal (e.g. `ASSERT_*`) failure in the\ncurrent thread whose message contains the given `substring`, or use\n\n```c++\n EXPECT_NONFATAL_FAILURE(statement, substring);\n```\n\nif you are expecting a non-fatal (e.g. `EXPECT_*`) failure.\n\nOnly failures in the current thread are checked to determine the result of this\ntype of expectations. If `statement` creates new threads, failures in these\nthreads are also ignored. If you want to catch failures in other threads as\nwell, use one of the following macros instead:\n\n```c++\n EXPECT_FATAL_FAILURE_ON_ALL_THREADS(statement, substring);\n EXPECT_NONFATAL_FAILURE_ON_ALL_THREADS(statement, substring);\n```\n\nNOTE: Assertions from multiple threads are currently not supported on Windows.\n\nFor technical reasons, there are some caveats:\n\n1. You cannot stream a failure message to either macro.\n\n2. `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()` cannot reference\n local non-static variables or non-static members of `this` object.\n\n3. `statement` in `EXPECT_FATAL_FAILURE{_ON_ALL_THREADS}()` cannot return a\n value.\n\n## Registering tests programmatically\n\nThe `TEST` macros handle the vast majority of all use cases, but there are few\nwhere runtime registration logic is required. For those cases, the framework\nprovides the `::testing::RegisterTest` that allows callers to register arbitrary\ntests dynamically.\n\nThis is an advanced API only to be used when the `TEST` macros are insufficient.\nThe macros should be preferred when possible, as they avoid most of the\ncomplexity of calling this function.\n\nIt provides the following signature:\n\n```c++\ntemplate \nTestInfo* RegisterTest(const char* test_suite_name, const char* test_name,\n const char* type_param, const char* value_param,\n const char* file, int line, Factory factory);\n```\n\nThe `factory` argument is a factory callable (move-constructible) object or\nfunction pointer that creates a new instance of the Test object. It handles\nownership to the caller. The signature of the callable is `Fixture*()`, where\n`Fixture` is the test fixture class for the test. All tests registered with the\nsame `test_suite_name` must return the same fixture type. This is checked at\nruntime.\n\nThe framework will infer the fixture class from the factory and will call the\n`SetUpTestSuite` and `TearDownTestSuite` for it.\n\nMust be called before `RUN_ALL_TESTS()` is invoked, otherwise behavior is\nundefined.\n\nUse case example:\n\n```c++\nclass MyFixture : public ::testing::Test {\n public:\n // All of these optional, just like in regular macro usage.\n static void SetUpTestSuite() { ... }\n static void TearDownTestSuite() { ... }\n void SetUp() override { ... }\n void TearDown() override { ... }\n};\n\nclass MyTest : public MyFixture {\n public:\n explicit MyTest(int data) : data_(data) {}\n void TestBody() override { ... }\n\n private:\n int data_;\n};\n\nvoid RegisterMyTests(const std::vector& values) {\n for (int v : values) {\n ::testing::RegisterTest(\n \"MyFixture\", (\"Test\" + std::to_string(v)).c_str(), nullptr,\n std::to_string(v).c_str(),\n __FILE__, __LINE__,\n // Important to use the fixture type as the return type here.\n [=]() -> MyFixture* { return new MyTest(v); });\n }\n}\n...\nint main(int argc, char** argv) {\n std::vector values_to_test = LoadValuesFromConfig();\n RegisterMyTests(values_to_test);\n ...\n return RUN_ALL_TESTS();\n}\n```\n## Getting the Current Test's Name\n\nSometimes a function may need to know the name of the currently running test.\nFor example, you may be using the `SetUp()` method of your test fixture to set\nthe golden file name based on which test is running. The `::testing::TestInfo`\nclass has this information:\n\n```c++\nnamespace testing {\n\nclass TestInfo {\n public:\n // Returns the test suite name and the test name, respectively.\n //\n // Do NOT delete or free the return value - it's managed by the\n // TestInfo class.\n const char* test_suite_name() const;\n const char* name() const;\n};\n\n}\n```\n\nTo obtain a `TestInfo` object for the currently running test, call\n`current_test_info()` on the `UnitTest` singleton object:\n\n```c++\n // Gets information about the currently running test.\n // Do NOT delete the returned object - it's managed by the UnitTest class.\n const ::testing::TestInfo* const test_info =\n ::testing::UnitTest::GetInstance()->current_test_info();\n\n printf(\"We are in test %s of test suite %s.\\n\",\n test_info->name(),\n test_info->test_suite_name());\n```\n\n`current_test_info()` returns a null pointer if no test is running. In\nparticular, you cannot find the test suite name in `TestSuiteSetUp()`,\n`TestSuiteTearDown()` (where you know the test suite name implicitly), or\nfunctions called from them.\n\n## Extending googletest by Handling Test Events\n\ngoogletest provides an **event listener API** to let you receive notifications\nabout the progress of a test program and test failures. The events you can\nlisten to include the start and end of the test program, a test suite, or a test\nmethod, among others. You may use this API to augment or replace the standard\nconsole output, replace the XML output, or provide a completely different form\nof output, such as a GUI or a database. You can also use test events as\ncheckpoints to implement a resource leak checker, for example.\n\n### Defining Event Listeners\n\nTo define a event listener, you subclass either testing::TestEventListener or\ntesting::EmptyTestEventListener The former is an (abstract) interface, where\n*each pure virtual method can be overridden to handle a test event* (For\nexample, when a test starts, the `OnTestStart()` method will be called.). The\nlatter provides an empty implementation of all methods in the interface, such\nthat a subclass only needs to override the methods it cares about.\n\nWhen an event is fired, its context is passed to the handler function as an\nargument. The following argument types are used:\n\n* UnitTest reflects the state of the entire test program,\n* TestSuite has information about a test suite, which can contain one or more\n tests,\n* TestInfo contains the state of a test, and\n* TestPartResult represents the result of a test assertion.\n\nAn event handler function can examine the argument it receives to find out\ninteresting information about the event and the test program's state.\n\nHere's an example:\n\n```c++\n class MinimalistPrinter : public ::testing::EmptyTestEventListener {\n // Called before a test starts.\n virtual void OnTestStart(const ::testing::TestInfo& test_info) {\n printf(\"*** Test %s.%s starting.\\n\",\n test_info.test_suite_name(), test_info.name());\n }\n\n // Called after a failed assertion or a SUCCESS().\n virtual void OnTestPartResult(const ::testing::TestPartResult& test_part_result) {\n printf(\"%s in %s:%d\\n%s\\n\",\n test_part_result.failed() ? \"*** Failure\" : \"Success\",\n test_part_result.file_name(),\n test_part_result.line_number(),\n test_part_result.summary());\n }\n\n // Called after a test ends.\n virtual void OnTestEnd(const ::testing::TestInfo& test_info) {\n printf(\"*** Test %s.%s ending.\\n\",\n test_info.test_suite_name(), test_info.name());\n }\n };\n```\n\n### Using Event Listeners\n\nTo use the event listener you have defined, add an instance of it to the\ngoogletest event listener list (represented by class TestEventListeners - note\nthe \"s\" at the end of the name) in your `main()` function, before calling\n`RUN_ALL_TESTS()`:\n\n```c++\nint main(int argc, char** argv) {\n ::testing::InitGoogleTest(&argc, argv);\n // Gets hold of the event listener list.\n ::testing::TestEventListeners& listeners =\n ::testing::UnitTest::GetInstance()->listeners();\n // Adds a listener to the end. googletest takes the ownership.\n listeners.Append(new MinimalistPrinter);\n return RUN_ALL_TESTS();\n}\n```\n\nThere's only one problem: the default test result printer is still in effect, so\nits output will mingle with the output from your minimalist printer. To suppress\nthe default printer, just release it from the event listener list and delete it.\nYou can do so by adding one line:\n\n```c++\n ...\n delete listeners.Release(listeners.default_result_printer());\n listeners.Append(new MinimalistPrinter);\n return RUN_ALL_TESTS();\n```\n\nNow, sit back and enjoy a completely different output from your tests. For more\ndetails, see [sample9_unittest.cc].\n\n[sample9_unittest.cc]: ../samples/sample9_unittest.cc \"Event listener example\"\n\nYou may append more than one listener to the list. When an `On*Start()` or\n`OnTestPartResult()` event is fired, the listeners will receive it in the order\nthey appear in the list (since new listeners are added to the end of the list,\nthe default text printer and the default XML generator will receive the event\nfirst). An `On*End()` event will be received by the listeners in the *reverse*\norder. This allows output by listeners added later to be framed by output from\nlisteners added earlier.\n\n### Generating Failures in Listeners\n\nYou may use failure-raising macros (`EXPECT_*()`, `ASSERT_*()`, `FAIL()`, etc)\nwhen processing an event. There are some restrictions:\n\n1. You cannot generate any failure in `OnTestPartResult()` (otherwise it will\n cause `OnTestPartResult()` to be called recursively).\n2. A listener that handles `OnTestPartResult()` is not allowed to generate any\n failure.\n\nWhen you add listeners to the listener list, you should put listeners that\nhandle `OnTestPartResult()` *before* listeners that can generate failures. This\nensures that failures generated by the latter are attributed to the right test\nby the former.\n\nSee [sample10_unittest.cc] for an example of a failure-raising listener.\n\n[sample10_unittest.cc]: ../samples/sample10_unittest.cc \"Failure-raising listener example\"\n\n## Running Test Programs: Advanced Options\n\ngoogletest test programs are ordinary executables. Once built, you can run them\ndirectly and affect their behavior via the following environment variables\nand/or command line flags. For the flags to work, your programs must call\n`::testing::InitGoogleTest()` before calling `RUN_ALL_TESTS()`.\n\nTo see a list of supported flags and their usage, please run your test program\nwith the `--help` flag. You can also use `-h`, `-?`, or `/?` for short.\n\nIf an option is specified both by an environment variable and by a flag, the\nlatter takes precedence.\n\n### Selecting Tests\n\n#### Listing Test Names\n\nSometimes it is necessary to list the available tests in a program before\nrunning them so that a filter may be applied if needed. Including the flag\n`--gtest_list_tests` overrides all other flags and lists tests in the following\nformat:\n\n```none\nTestSuite1.\n TestName1\n TestName2\nTestSuite2.\n TestName\n```\n\nNone of the tests listed are actually run if the flag is provided. There is no\ncorresponding environment variable for this flag.\n\n#### Running a Subset of the Tests\n\nBy default, a googletest program runs all tests the user has defined. Sometimes,\nyou want to run only a subset of the tests (e.g. for debugging or quickly\nverifying a change). If you set the `GTEST_FILTER` environment variable or the\n`--gtest_filter` flag to a filter string, googletest will only run the tests\nwhose full names (in the form of `TestSuiteName.TestName`) match the filter.\n\nThe format of a filter is a '`:`'-separated list of wildcard patterns (called\nthe *positive patterns*) optionally followed by a '`-`' and another\n'`:`'-separated pattern list (called the *negative patterns*). A test matches\nthe filter if and only if it matches any of the positive patterns but does not\nmatch any of the negative patterns.\n\nA pattern may contain `'*'` (matches any string) or `'?'` (matches any single\ncharacter). For convenience, the filter `'*-NegativePatterns'` can be also\nwritten as `'-NegativePatterns'`.\n\nFor example:\n\n* `./foo_test` Has no flag, and thus runs all its tests.\n* `./foo_test --gtest_filter=*` Also runs everything, due to the single\n match-everything `*` value.\n* `./foo_test --gtest_filter=FooTest.*` Runs everything in test suite\n `FooTest` .\n* `./foo_test --gtest_filter=*Null*:*Constructor*` Runs any test whose full\n name contains either `\"Null\"` or `\"Constructor\"` .\n* `./foo_test --gtest_filter=-*DeathTest.*` Runs all non-death tests.\n* `./foo_test --gtest_filter=FooTest.*-FooTest.Bar` Runs everything in test\n suite `FooTest` except `FooTest.Bar`.\n* `./foo_test --gtest_filter=FooTest.*:BarTest.*-FooTest.Bar:BarTest.Foo` Runs\n everything in test suite `FooTest` except `FooTest.Bar` and everything in\n test suite `BarTest` except `BarTest.Foo`.\n\n#### Temporarily Disabling Tests\n\nIf you have a broken test that you cannot fix right away, you can add the\n`DISABLED_` prefix to its name. This will exclude it from execution. This is\nbetter than commenting out the code or using `#if 0`, as disabled tests are\nstill compiled (and thus won't rot).\n\nIf you need to disable all tests in a test suite, you can either add `DISABLED_`\nto the front of the name of each test, or alternatively add it to the front of\nthe test suite name.\n\nFor example, the following tests won't be run by googletest, even though they\nwill still be compiled:\n\n```c++\n// Tests that Foo does Abc.\nTEST(FooTest, DISABLED_DoesAbc) { ... }\n\nclass DISABLED_BarTest : public ::testing::Test { ... };\n\n// Tests that Bar does Xyz.\nTEST_F(DISABLED_BarTest, DoesXyz) { ... }\n```\n\nNOTE: This feature should only be used for temporary pain-relief. You still have\nto fix the disabled tests at a later date. As a reminder, googletest will print\na banner warning you if a test program contains any disabled tests.\n\nTIP: You can easily count the number of disabled tests you have using `gsearch`\nand/or `grep`. This number can be used as a metric for improving your test\nquality.\n\n#### Temporarily Enabling Disabled Tests\n\nTo include disabled tests in test execution, just invoke the test program with\nthe `--gtest_also_run_disabled_tests` flag or set the\n`GTEST_ALSO_RUN_DISABLED_TESTS` environment variable to a value other than `0`.\nYou can combine this with the `--gtest_filter` flag to further select which\ndisabled tests to run.\n\n### Repeating the Tests\n\nOnce in a while you'll run into a test whose result is hit-or-miss. Perhaps it\nwill fail only 1% of the time, making it rather hard to reproduce the bug under\na debugger. This can be a major source of frustration.\n\nThe `--gtest_repeat` flag allows you to repeat all (or selected) test methods in\na program many times. Hopefully, a flaky test will eventually fail and give you\na chance to debug. Here's how to use it:\n\n```none\n$ foo_test --gtest_repeat=1000\nRepeat foo_test 1000 times and don't stop at failures.\n\n$ foo_test --gtest_repeat=-1\nA negative count means repeating forever.\n\n$ foo_test --gtest_repeat=1000 --gtest_break_on_failure\nRepeat foo_test 1000 times, stopping at the first failure. This\nis especially useful when running under a debugger: when the test\nfails, it will drop into the debugger and you can then inspect\nvariables and stacks.\n\n$ foo_test --gtest_repeat=1000 --gtest_filter=FooBar.*\nRepeat the tests whose name matches the filter 1000 times.\n```\n\nIf your test program contains\n[global set-up/tear-down](#global-set-up-and-tear-down) code, it will be\nrepeated in each iteration as well, as the flakiness may be in it. You can also\nspecify the repeat count by setting the `GTEST_REPEAT` environment variable.\n\n### Shuffling the Tests\n\nYou can specify the `--gtest_shuffle` flag (or set the `GTEST_SHUFFLE`\nenvironment variable to `1`) to run the tests in a program in a random order.\nThis helps to reveal bad dependencies between tests.\n\nBy default, googletest uses a random seed calculated from the current time.\nTherefore you'll get a different order every time. The console output includes\nthe random seed value, such that you can reproduce an order-related test failure\nlater. To specify the random seed explicitly, use the `--gtest_random_seed=SEED`\nflag (or set the `GTEST_RANDOM_SEED` environment variable), where `SEED` is an\ninteger in the range [0, 99999]. The seed value 0 is special: it tells\ngoogletest to do the default behavior of calculating the seed from the current\ntime.\n\nIf you combine this with `--gtest_repeat=N`, googletest will pick a different\nrandom seed and re-shuffle the tests in each iteration.\n\n### Controlling Test Output\n\n#### Colored Terminal Output\n\ngoogletest can use colors in its terminal output to make it easier to spot the\nimportant information:\n\n\n...
\n [----------] 1 test from\n FooTest
\n [ RUN      ]\n FooTest.DoesAbc
\n [       OK ]\n FooTest.DoesAbc
\n [----------]\n 2 tests from BarTest
\n [ RUN      ]\n BarTest.HasXyzProperty
\n [       OK ]\n BarTest.HasXyzProperty
\n [ RUN      ]\n BarTest.ReturnsTrueOnSuccess ... some error messages ...
\n [   FAILED ]\n BarTest.ReturnsTrueOnSuccess ...
\n [==========]\n 30 tests from 14 test suites ran.
\n [   PASSED ]\n 28 tests.
\n [   FAILED ]\n 2 tests, listed below:
\n [   FAILED ]\n BarTest.ReturnsTrueOnSuccess
\n [   FAILED ]\n AnotherTest.DoesXyz
\n
\n 2 FAILED TESTS\n \n\n\nYou can set the `GTEST_COLOR` environment variable or the `--gtest_color`\ncommand line flag to `yes`, `no`, or `auto` (the default) to enable colors,\ndisable colors, or let googletest decide. When the value is `auto`, googletest\nwill use colors if and only if the output goes to a terminal and (on non-Windows\nplatforms) the `TERM` environment variable is set to `xterm` or `xterm-color`.\n\n#### Suppressing the Elapsed Time\n\nBy default, googletest prints the time it takes to run each test. To disable\nthat, run the test program with the `--gtest_print_time=0` command line flag, or\nset the GTEST_PRINT_TIME environment variable to `0`.\n\n#### Suppressing UTF-8 Text Output\n\nIn case of assertion failures, googletest prints expected and actual values of\ntype `string` both as hex-encoded strings as well as in readable UTF-8 text if\nthey contain valid non-ASCII UTF-8 characters. If you want to suppress the UTF-8\ntext because, for example, you don't have an UTF-8 compatible output medium, run\nthe test program with `--gtest_print_utf8=0` or set the `GTEST_PRINT_UTF8`\nenvironment variable to `0`.\n\n\n\n#### Generating an XML Report\n\ngoogletest can emit a detailed XML report to a file in addition to its normal\ntextual output. The report contains the duration of each test, and thus can help\nyou identify slow tests. The report is also used by the http://unittest\ndashboard to show per-test-method error messages.\n\nTo generate the XML report, set the `GTEST_OUTPUT` environment variable or the\n`--gtest_output` flag to the string `\"xml:path_to_output_file\"`, which will\ncreate the file at the given location. You can also just use the string `\"xml\"`,\nin which case the output can be found in the `test_detail.xml` file in the\ncurrent directory.\n\nIf you specify a directory (for example, `\"xml:output/directory/\"` on Linux or\n`\"xml:output\\directory\\\"` on Windows), googletest will create the XML file in\nthat directory, named after the test executable (e.g. `foo_test.xml` for test\nprogram `foo_test` or `foo_test.exe`). If the file already exists (perhaps left\nover from a previous run), googletest will pick a different name (e.g.\n`foo_test_1.xml`) to avoid overwriting it.\n\nThe report is based on the `junitreport` Ant task. Since that format was\noriginally intended for Java, a little interpretation is required to make it\napply to googletest tests, as shown here:\n\n```xml\n\n \n \n \n \n \n \n \n\n```\n\n* The root `` element corresponds to the entire test program.\n* `` elements correspond to googletest test suites.\n* `` elements correspond to googletest test functions.\n\nFor instance, the following program\n\n```c++\nTEST(MathTest, Addition) { ... }\nTEST(MathTest, Subtraction) { ... }\nTEST(LogicTest, NonContradiction) { ... }\n```\n\ncould generate this report:\n\n```xml\n\n\n \n \n ...\n ...\n \n \n \n \n \n \n \n \n\n```\n\nThings to note:\n\n* The `tests` attribute of a `` or `` element tells how\n many test functions the googletest program or test suite contains, while the\n `failures` attribute tells how many of them failed.\n\n* The `time` attribute expresses the duration of the test, test suite, or\n entire test program in seconds.\n\n* The `timestamp` attribute records the local date and time of the test\n execution.\n\n* Each `` element corresponds to a single failed googletest\n assertion.\n\n#### Generating a JSON Report\n\ngoogletest can also emit a JSON report as an alternative format to XML. To\ngenerate the JSON report, set the `GTEST_OUTPUT` environment variable or the\n`--gtest_output` flag to the string `\"json:path_to_output_file\"`, which will\ncreate the file at the given location. You can also just use the string\n`\"json\"`, in which case the output can be found in the `test_detail.json` file\nin the current directory.\n\nThe report format conforms to the following JSON Schema:\n\n```json\n{\n \"$schema\": \"http://json-schema.org/schema#\",\n \"type\": \"object\",\n \"definitions\": {\n \"TestCase\": {\n \"type\": \"object\",\n \"properties\": {\n \"name\": { \"type\": \"string\" },\n \"tests\": { \"type\": \"integer\" },\n \"failures\": { \"type\": \"integer\" },\n \"disabled\": { \"type\": \"integer\" },\n \"time\": { \"type\": \"string\" },\n \"testsuite\": {\n \"type\": \"array\",\n \"items\": {\n \"$ref\": \"#/definitions/TestInfo\"\n }\n }\n }\n },\n \"TestInfo\": {\n \"type\": \"object\",\n \"properties\": {\n \"name\": { \"type\": \"string\" },\n \"status\": {\n \"type\": \"string\",\n \"enum\": [\"RUN\", \"NOTRUN\"]\n },\n \"time\": { \"type\": \"string\" },\n \"classname\": { \"type\": \"string\" },\n \"failures\": {\n \"type\": \"array\",\n \"items\": {\n \"$ref\": \"#/definitions/Failure\"\n }\n }\n }\n },\n \"Failure\": {\n \"type\": \"object\",\n \"properties\": {\n \"failures\": { \"type\": \"string\" },\n \"type\": { \"type\": \"string\" }\n }\n }\n },\n \"properties\": {\n \"tests\": { \"type\": \"integer\" },\n \"failures\": { \"type\": \"integer\" },\n \"disabled\": { \"type\": \"integer\" },\n \"errors\": { \"type\": \"integer\" },\n \"timestamp\": {\n \"type\": \"string\",\n \"format\": \"date-time\"\n },\n \"time\": { \"type\": \"string\" },\n \"name\": { \"type\": \"string\" },\n \"testsuites\": {\n \"type\": \"array\",\n \"items\": {\n \"$ref\": \"#/definitions/TestCase\"\n }\n }\n }\n}\n```\n\nThe report uses the format that conforms to the following Proto3 using the\n[JSON encoding](https://developers.google.com/protocol-buffers/docs/proto3#json):\n\n```proto\nsyntax = \"proto3\";\n\npackage googletest;\n\nimport \"google/protobuf/timestamp.proto\";\nimport \"google/protobuf/duration.proto\";\n\nmessage UnitTest {\n int32 tests = 1;\n int32 failures = 2;\n int32 disabled = 3;\n int32 errors = 4;\n google.protobuf.Timestamp timestamp = 5;\n google.protobuf.Duration time = 6;\n string name = 7;\n repeated TestCase testsuites = 8;\n}\n\nmessage TestCase {\n string name = 1;\n int32 tests = 2;\n int32 failures = 3;\n int32 disabled = 4;\n int32 errors = 5;\n google.protobuf.Duration time = 6;\n repeated TestInfo testsuite = 7;\n}\n\nmessage TestInfo {\n string name = 1;\n enum Status {\n RUN = 0;\n NOTRUN = 1;\n }\n Status status = 2;\n google.protobuf.Duration time = 3;\n string classname = 4;\n message Failure {\n string failures = 1;\n string type = 2;\n }\n repeated Failure failures = 5;\n}\n```\n\nFor instance, the following program\n\n```c++\nTEST(MathTest, Addition) { ... }\nTEST(MathTest, Subtraction) { ... }\nTEST(LogicTest, NonContradiction) { ... }\n```\n\ncould generate this report:\n\n```json\n{\n \"tests\": 3,\n \"failures\": 1,\n \"errors\": 0,\n \"time\": \"0.035s\",\n \"timestamp\": \"2011-10-31T18:52:42Z\",\n \"name\": \"AllTests\",\n \"testsuites\": [\n {\n \"name\": \"MathTest\",\n \"tests\": 2,\n \"failures\": 1,\n \"errors\": 0,\n \"time\": \"0.015s\",\n \"testsuite\": [\n {\n \"name\": \"Addition\",\n \"status\": \"RUN\",\n \"time\": \"0.007s\",\n \"classname\": \"\",\n \"failures\": [\n {\n \"message\": \"Value of: add(1, 1)\\n Actual: 3\\nExpected: 2\",\n \"type\": \"\"\n },\n {\n \"message\": \"Value of: add(1, -1)\\n Actual: 1\\nExpected: 0\",\n \"type\": \"\"\n }\n ]\n },\n {\n \"name\": \"Subtraction\",\n \"status\": \"RUN\",\n \"time\": \"0.005s\",\n \"classname\": \"\"\n }\n ]\n },\n {\n \"name\": \"LogicTest\",\n \"tests\": 1,\n \"failures\": 0,\n \"errors\": 0,\n \"time\": \"0.005s\",\n \"testsuite\": [\n {\n \"name\": \"NonContradiction\",\n \"status\": \"RUN\",\n \"time\": \"0.005s\",\n \"classname\": \"\"\n }\n ]\n }\n ]\n}\n```\n\nIMPORTANT: The exact format of the JSON document is subject to change.\n\n### Controlling How Failures Are Reported\n\n#### Turning Assertion Failures into Break-Points\n\nWhen running test programs under a debugger, it's very convenient if the\ndebugger can catch an assertion failure and automatically drop into interactive\nmode. googletest's *break-on-failure* mode supports this behavior.\n\nTo enable it, set the `GTEST_BREAK_ON_FAILURE` environment variable to a value\nother than `0`. Alternatively, you can use the `--gtest_break_on_failure`\ncommand line flag.\n\n#### Disabling Catching Test-Thrown Exceptions\n\ngoogletest can be used either with or without exceptions enabled. If a test\nthrows a C++ exception or (on Windows) a structured exception (SEH), by default\ngoogletest catches it, reports it as a test failure, and continues with the next\ntest method. This maximizes the coverage of a test run. Also, on Windows an\nuncaught exception will cause a pop-up window, so catching the exceptions allows\nyou to run the tests automatically.\n\nWhen debugging the test failures, however, you may instead want the exceptions\nto be handled by the debugger, such that you can examine the call stack when an\nexception is thrown. To achieve that, set the `GTEST_CATCH_EXCEPTIONS`\nenvironment variable to `0`, or use the `--gtest_catch_exceptions=0` flag when\nrunning the tests.\n" }, { "path": "test/googletest/docs/faq.md", "content": "# Googletest FAQ\n\n\n\n## Why should test suite names and test names not contain underscore?\n\nUnderscore (`_`) is special, as C++ reserves the following to be used by the\ncompiler and the standard library:\n\n1. any identifier that starts with an `_` followed by an upper-case letter, and\n2. any identifier that contains two consecutive underscores (i.e. `__`)\n *anywhere* in its name.\n\nUser code is *prohibited* from using such identifiers.\n\nNow let's look at what this means for `TEST` and `TEST_F`.\n\nCurrently `TEST(TestSuiteName, TestName)` generates a class named\n`TestSuiteName_TestName_Test`. What happens if `TestSuiteName` or `TestName`\ncontains `_`?\n\n1. If `TestSuiteName` starts with an `_` followed by an upper-case letter (say,\n `_Foo`), we end up with `_Foo_TestName_Test`, which is reserved and thus\n invalid.\n2. If `TestSuiteName` ends with an `_` (say, `Foo_`), we get\n `Foo__TestName_Test`, which is invalid.\n3. If `TestName` starts with an `_` (say, `_Bar`), we get\n `TestSuiteName__Bar_Test`, which is invalid.\n4. If `TestName` ends with an `_` (say, `Bar_`), we get\n `TestSuiteName_Bar__Test`, which is invalid.\n\nSo clearly `TestSuiteName` and `TestName` cannot start or end with `_`\n(Actually, `TestSuiteName` can start with `_` -- as long as the `_` isn't\nfollowed by an upper-case letter. But that's getting complicated. So for\nsimplicity we just say that it cannot start with `_`.).\n\nIt may seem fine for `TestSuiteName` and `TestName` to contain `_` in the\nmiddle. However, consider this:\n\n```c++\nTEST(Time, Flies_Like_An_Arrow) { ... }\nTEST(Time_Flies, Like_An_Arrow) { ... }\n```\n\nNow, the two `TEST`s will both generate the same class\n(`Time_Flies_Like_An_Arrow_Test`). That's not good.\n\nSo for simplicity, we just ask the users to avoid `_` in `TestSuiteName` and\n`TestName`. The rule is more constraining than necessary, but it's simple and\neasy to remember. It also gives googletest some wiggle room in case its\nimplementation needs to change in the future.\n\nIf you violate the rule, there may not be immediate consequences, but your test\nmay (just may) break with a new compiler (or a new version of the compiler you\nare using) or with a new version of googletest. Therefore it's best to follow\nthe rule.\n\n## Why does googletest support `EXPECT_EQ(NULL, ptr)` and `ASSERT_EQ(NULL, ptr)` but not `EXPECT_NE(NULL, ptr)` and `ASSERT_NE(NULL, ptr)`?\n\nFirst of all you can use `EXPECT_NE(nullptr, ptr)` and `ASSERT_NE(nullptr,\nptr)`. This is the preferred syntax in the style guide because nullptr does not\nhave the type problems that NULL does. Which is why NULL does not work.\n\nDue to some peculiarity of C++, it requires some non-trivial template meta\nprogramming tricks to support using `NULL` as an argument of the `EXPECT_XX()`\nand `ASSERT_XX()` macros. Therefore we only do it where it's most needed\n(otherwise we make the implementation of googletest harder to maintain and more\nerror-prone than necessary).\n\nThe `EXPECT_EQ()` macro takes the *expected* value as its first argument and the\n*actual* value as the second. It's reasonable that someone wants to write\n`EXPECT_EQ(NULL, some_expression)`, and this indeed was requested several times.\nTherefore we implemented it.\n\nThe need for `EXPECT_NE(NULL, ptr)` isn't nearly as strong. When the assertion\nfails, you already know that `ptr` must be `NULL`, so it doesn't add any\ninformation to print `ptr` in this case. That means `EXPECT_TRUE(ptr != NULL)`\nworks just as well.\n\nIf we were to support `EXPECT_NE(NULL, ptr)`, for consistency we'll have to\nsupport `EXPECT_NE(ptr, NULL)` as well, as unlike `EXPECT_EQ`, we don't have a\nconvention on the order of the two arguments for `EXPECT_NE`. This means using\nthe template meta programming tricks twice in the implementation, making it even\nharder to understand and maintain. We believe the benefit doesn't justify the\ncost.\n\nFinally, with the growth of the gMock matcher library, we are encouraging people\nto use the unified `EXPECT_THAT(value, matcher)` syntax more often in tests. One\nsignificant advantage of the matcher approach is that matchers can be easily\ncombined to form new matchers, while the `EXPECT_NE`, etc, macros cannot be\neasily combined. Therefore we want to invest more in the matchers than in the\n`EXPECT_XX()` macros.\n\n## I need to test that different implementations of an interface satisfy some common requirements. Should I use typed tests or value-parameterized tests?\n\nFor testing various implementations of the same interface, either typed tests or\nvalue-parameterized tests can get it done. It's really up to you the user to\ndecide which is more convenient for you, depending on your particular case. Some\nrough guidelines:\n\n* Typed tests can be easier to write if instances of the different\n implementations can be created the same way, modulo the type. For example,\n if all these implementations have a public default constructor (such that\n you can write `new TypeParam`), or if their factory functions have the same\n form (e.g. `CreateInstance()`).\n* Value-parameterized tests can be easier to write if you need different code\n patterns to create different implementations' instances, e.g. `new Foo` vs\n `new Bar(5)`. To accommodate for the differences, you can write factory\n function wrappers and pass these function pointers to the tests as their\n parameters.\n* When a typed test fails, the default output includes the name of the type,\n which can help you quickly identify which implementation is wrong.\n Value-parameterized tests only show the number of the failed iteration by\n default. You will need to define a function that returns the iteration name\n and pass it as the third parameter to INSTANTIATE_TEST_SUITE_P to have more\n useful output.\n* When using typed tests, you need to make sure you are testing against the\n interface type, not the concrete types (in other words, you want to make\n sure `implicit_cast(my_concrete_impl)` works, not just that\n `my_concrete_impl` works). It's less likely to make mistakes in this area\n when using value-parameterized tests.\n\nI hope I didn't confuse you more. :-) If you don't mind, I'd suggest you to give\nboth approaches a try. Practice is a much better way to grasp the subtle\ndifferences between the two tools. Once you have some concrete experience, you\ncan much more easily decide which one to use the next time.\n\n## I got some run-time errors about invalid proto descriptors when using `ProtocolMessageEquals`. Help!\n\n**Note:** `ProtocolMessageEquals` and `ProtocolMessageEquiv` are *deprecated*\nnow. Please use `EqualsProto`, etc instead.\n\n`ProtocolMessageEquals` and `ProtocolMessageEquiv` were redefined recently and\nare now less tolerant of invalid protocol buffer definitions. In particular, if\nyou have a `foo.proto` that doesn't fully qualify the type of a protocol message\nit references (e.g. `message` where it should be `message`), you\nwill now get run-time errors like:\n\n```\n... descriptor.cc:...] Invalid proto descriptor for file \"path/to/foo.proto\":\n... descriptor.cc:...] blah.MyMessage.my_field: \".Bar\" is not defined.\n```\n\nIf you see this, your `.proto` file is broken and needs to be fixed by making\nthe types fully qualified. The new definition of `ProtocolMessageEquals` and\n`ProtocolMessageEquiv` just happen to reveal your bug.\n\n## My death test modifies some state, but the change seems lost after the death test finishes. Why?\n\nDeath tests (`EXPECT_DEATH`, etc) are executed in a sub-process s.t. the\nexpected crash won't kill the test program (i.e. the parent process). As a\nresult, any in-memory side effects they incur are observable in their respective\nsub-processes, but not in the parent process. You can think of them as running\nin a parallel universe, more or less.\n\nIn particular, if you use mocking and the death test statement invokes some mock\nmethods, the parent process will think the calls have never occurred. Therefore,\nyou may want to move your `EXPECT_CALL` statements inside the `EXPECT_DEATH`\nmacro.\n\n## EXPECT_EQ(htonl(blah), blah_blah) generates weird compiler errors in opt mode. Is this a googletest bug?\n\nActually, the bug is in `htonl()`.\n\nAccording to `'man htonl'`, `htonl()` is a *function*, which means it's valid to\nuse `htonl` as a function pointer. However, in opt mode `htonl()` is defined as\na *macro*, which breaks this usage.\n\nWorse, the macro definition of `htonl()` uses a `gcc` extension and is *not*\nstandard C++. That hacky implementation has some ad hoc limitations. In\nparticular, it prevents you from writing `Foo()`, where `Foo`\nis a template that has an integral argument.\n\nThe implementation of `EXPECT_EQ(a, b)` uses `sizeof(... a ...)` inside a\ntemplate argument, and thus doesn't compile in opt mode when `a` contains a call\nto `htonl()`. It is difficult to make `EXPECT_EQ` bypass the `htonl()` bug, as\nthe solution must work with different compilers on various platforms.\n\n`htonl()` has some other problems as described in `//util/endian/endian.h`,\nwhich defines `ghtonl()` to replace it. `ghtonl()` does the same thing `htonl()`\ndoes, only without its problems. We suggest you to use `ghtonl()` instead of\n`htonl()`, both in your tests and production code.\n\n`//util/endian/endian.h` also defines `ghtons()`, which solves similar problems\nin `htons()`.\n\nDon't forget to add `//util/endian` to the list of dependencies in the `BUILD`\nfile wherever `ghtonl()` and `ghtons()` are used. The library consists of a\nsingle header file and will not bloat your binary.\n\n## The compiler complains about \"undefined references\" to some static const member variables, but I did define them in the class body. What's wrong?\n\nIf your class has a static data member:\n\n```c++\n// foo.h\nclass Foo {\n ...\n static const int kBar = 100;\n};\n```\n\nYou also need to define it *outside* of the class body in `foo.cc`:\n\n```c++\nconst int Foo::kBar; // No initializer here.\n```\n\nOtherwise your code is **invalid C++**, and may break in unexpected ways. In\nparticular, using it in googletest comparison assertions (`EXPECT_EQ`, etc) will\ngenerate an \"undefined reference\" linker error. The fact that \"it used to work\"\ndoesn't mean it's valid. It just means that you were lucky. :-)\n\n## Can I derive a test fixture from another?\n\nYes.\n\nEach test fixture has a corresponding and same named test suite. This means only\none test suite can use a particular fixture. Sometimes, however, multiple test\ncases may want to use the same or slightly different fixtures. For example, you\nmay want to make sure that all of a GUI library's test suites don't leak\nimportant system resources like fonts and brushes.\n\nIn googletest, you share a fixture among test suites by putting the shared logic\nin a base test fixture, then deriving from that base a separate fixture for each\ntest suite that wants to use this common logic. You then use `TEST_F()` to write\ntests using each derived fixture.\n\nTypically, your code looks like this:\n\n```c++\n// Defines a base test fixture.\nclass BaseTest : public ::testing::Test {\n protected:\n ...\n};\n\n// Derives a fixture FooTest from BaseTest.\nclass FooTest : public BaseTest {\n protected:\n void SetUp() override {\n BaseTest::SetUp(); // Sets up the base fixture first.\n ... additional set-up work ...\n }\n\n void TearDown() override {\n ... clean-up work for FooTest ...\n BaseTest::TearDown(); // Remember to tear down the base fixture\n // after cleaning up FooTest!\n }\n\n ... functions and variables for FooTest ...\n};\n\n// Tests that use the fixture FooTest.\nTEST_F(FooTest, Bar) { ... }\nTEST_F(FooTest, Baz) { ... }\n\n... additional fixtures derived from BaseTest ...\n```\n\nIf necessary, you can continue to derive test fixtures from a derived fixture.\ngoogletest has no limit on how deep the hierarchy can be.\n\nFor a complete example using derived test fixtures, see\n[sample5_unittest.cc](../samples/sample5_unittest.cc).\n\n## My compiler complains \"void value not ignored as it ought to be.\" What does this mean?\n\nYou're probably using an `ASSERT_*()` in a function that doesn't return `void`.\n`ASSERT_*()` can only be used in `void` functions, due to exceptions being\ndisabled by our build system. Please see more details\n[here](advanced.md#assertion-placement).\n\n## My death test hangs (or seg-faults). How do I fix it?\n\nIn googletest, death tests are run in a child process and the way they work is\ndelicate. To write death tests you really need to understand how they work.\nPlease make sure you have read [this](advanced.md#how-it-works).\n\nIn particular, death tests don't like having multiple threads in the parent\nprocess. So the first thing you can try is to eliminate creating threads outside\nof `EXPECT_DEATH()`. For example, you may want to use mocks or fake objects\ninstead of real ones in your tests.\n\nSometimes this is impossible as some library you must use may be creating\nthreads before `main()` is even reached. In this case, you can try to minimize\nthe chance of conflicts by either moving as many activities as possible inside\n`EXPECT_DEATH()` (in the extreme case, you want to move everything inside), or\nleaving as few things as possible in it. Also, you can try to set the death test\nstyle to `\"threadsafe\"`, which is safer but slower, and see if it helps.\n\nIf you go with thread-safe death tests, remember that they rerun the test\nprogram from the beginning in the child process. Therefore make sure your\nprogram can run side-by-side with itself and is deterministic.\n\nIn the end, this boils down to good concurrent programming. You have to make\nsure that there is no race conditions or dead locks in your program. No silver\nbullet - sorry!\n\n## Should I use the constructor/destructor of the test fixture or SetUp()/TearDown()? {#CtorVsSetUp}\n\nThe first thing to remember is that googletest does **not** reuse the same test\nfixture object across multiple tests. For each `TEST_F`, googletest will create\na **fresh** test fixture object, immediately call `SetUp()`, run the test body,\ncall `TearDown()`, and then delete the test fixture object.\n\nWhen you need to write per-test set-up and tear-down logic, you have the choice\nbetween using the test fixture constructor/destructor or `SetUp()/TearDown()`.\nThe former is usually preferred, as it has the following benefits:\n\n* By initializing a member variable in the constructor, we have the option to\n make it `const`, which helps prevent accidental changes to its value and\n makes the tests more obviously correct.\n* In case we need to subclass the test fixture class, the subclass'\n constructor is guaranteed to call the base class' constructor *first*, and\n the subclass' destructor is guaranteed to call the base class' destructor\n *afterward*. With `SetUp()/TearDown()`, a subclass may make the mistake of\n forgetting to call the base class' `SetUp()/TearDown()` or call them at the\n wrong time.\n\nYou may still want to use `SetUp()/TearDown()` in the following cases:\n\n* C++ does not allow virtual function calls in constructors and destructors.\n You can call a method declared as virtual, but it will not use dynamic\n dispatch, it will use the definition from the class the constructor of which\n is currently executing. This is because calling a virtual method before the\n derived class constructor has a chance to run is very dangerous - the\n virtual method might operate on uninitialized data. Therefore, if you need\n to call a method that will be overridden in a derived class, you have to use\n `SetUp()/TearDown()`.\n* In the body of a constructor (or destructor), it's not possible to use the\n `ASSERT_xx` macros. Therefore, if the set-up operation could cause a fatal\n test failure that should prevent the test from running, it's necessary to\n use `abort` and abort the whole test executable,\n or to use `SetUp()` instead of a constructor.\n* If the tear-down operation could throw an exception, you must use\n `TearDown()` as opposed to the destructor, as throwing in a destructor leads\n to undefined behavior and usually will kill your program right away. Note\n that many standard libraries (like STL) may throw when exceptions are\n enabled in the compiler. Therefore you should prefer `TearDown()` if you\n want to write portable tests that work with or without exceptions.\n* The googletest team is considering making the assertion macros throw on\n platforms where exceptions are enabled (e.g. Windows, Mac OS, and Linux\n client-side), which will eliminate the need for the user to propagate\n failures from a subroutine to its caller. Therefore, you shouldn't use\n googletest assertions in a destructor if your code could run on such a\n platform.\n\n## The compiler complains \"no matching function to call\" when I use ASSERT_PRED*. How do I fix it?\n\nIf the predicate function you use in `ASSERT_PRED*` or `EXPECT_PRED*` is\noverloaded or a template, the compiler will have trouble figuring out which\noverloaded version it should use. `ASSERT_PRED_FORMAT*` and\n`EXPECT_PRED_FORMAT*` don't have this problem.\n\nIf you see this error, you might want to switch to\n`(ASSERT|EXPECT)_PRED_FORMAT*`, which will also give you a better failure\nmessage. If, however, that is not an option, you can resolve the problem by\nexplicitly telling the compiler which version to pick.\n\nFor example, suppose you have\n\n```c++\nbool IsPositive(int n) {\n return n > 0;\n}\n\nbool IsPositive(double x) {\n return x > 0;\n}\n```\n\nyou will get a compiler error if you write\n\n```c++\nEXPECT_PRED1(IsPositive, 5);\n```\n\nHowever, this will work:\n\n```c++\nEXPECT_PRED1(static_cast(IsPositive), 5);\n```\n\n(The stuff inside the angled brackets for the `static_cast` operator is the type\nof the function pointer for the `int`-version of `IsPositive()`.)\n\nAs another example, when you have a template function\n\n```c++\ntemplate \nbool IsNegative(T x) {\n return x < 0;\n}\n```\n\nyou can use it in a predicate assertion like this:\n\n```c++\nASSERT_PRED1(IsNegative, -5);\n```\n\nThings are more interesting if your template has more than one parameters. The\nfollowing won't compile:\n\n```c++\nASSERT_PRED2(GreaterThan, 5, 0);\n```\n\nas the C++ pre-processor thinks you are giving `ASSERT_PRED2` 4 arguments, which\nis one more than expected. The workaround is to wrap the predicate function in\nparentheses:\n\n```c++\nASSERT_PRED2((GreaterThan), 5, 0);\n```\n\n## My compiler complains about \"ignoring return value\" when I call RUN_ALL_TESTS(). Why?\n\nSome people had been ignoring the return value of `RUN_ALL_TESTS()`. That is,\ninstead of\n\n```c++\n return RUN_ALL_TESTS();\n```\n\nthey write\n\n```c++\n RUN_ALL_TESTS();\n```\n\nThis is **wrong and dangerous**. The testing services needs to see the return\nvalue of `RUN_ALL_TESTS()` in order to determine if a test has passed. If your\n`main()` function ignores it, your test will be considered successful even if it\nhas a googletest assertion failure. Very bad.\n\nWe have decided to fix this (thanks to Michael Chastain for the idea). Now, your\ncode will no longer be able to ignore `RUN_ALL_TESTS()` when compiled with\n`gcc`. If you do so, you'll get a compiler error.\n\nIf you see the compiler complaining about you ignoring the return value of\n`RUN_ALL_TESTS()`, the fix is simple: just make sure its value is used as the\nreturn value of `main()`.\n\nBut how could we introduce a change that breaks existing tests? Well, in this\ncase, the code was already broken in the first place, so we didn't break it. :-)\n\n## My compiler complains that a constructor (or destructor) cannot return a value. What's going on?\n\nDue to a peculiarity of C++, in order to support the syntax for streaming\nmessages to an `ASSERT_*`, e.g.\n\n```c++\n ASSERT_EQ(1, Foo()) << \"blah blah\" << foo;\n```\n\nwe had to give up using `ASSERT*` and `FAIL*` (but not `EXPECT*` and\n`ADD_FAILURE*`) in constructors and destructors. The workaround is to move the\ncontent of your constructor/destructor to a private void member function, or\nswitch to `EXPECT_*()` if that works. This\n[section](advanced.md#assertion-placement) in the user's guide explains it.\n\n## My SetUp() function is not called. Why?\n\nC++ is case-sensitive. Did you spell it as `Setup()`?\n\nSimilarly, sometimes people spell `SetUpTestSuite()` as `SetupTestSuite()` and\nwonder why it's never called.\n\n\n## I have several test suites which share the same test fixture logic, do I have to define a new test fixture class for each of them? This seems pretty tedious.\n\nYou don't have to. Instead of\n\n```c++\nclass FooTest : public BaseTest {};\n\nTEST_F(FooTest, Abc) { ... }\nTEST_F(FooTest, Def) { ... }\n\nclass BarTest : public BaseTest {};\n\nTEST_F(BarTest, Abc) { ... }\nTEST_F(BarTest, Def) { ... }\n```\n\nyou can simply `typedef` the test fixtures:\n\n```c++\ntypedef BaseTest FooTest;\n\nTEST_F(FooTest, Abc) { ... }\nTEST_F(FooTest, Def) { ... }\n\ntypedef BaseTest BarTest;\n\nTEST_F(BarTest, Abc) { ... }\nTEST_F(BarTest, Def) { ... }\n```\n\n## googletest output is buried in a whole bunch of LOG messages. What do I do?\n\nThe googletest output is meant to be a concise and human-friendly report. If\nyour test generates textual output itself, it will mix with the googletest\noutput, making it hard to read. However, there is an easy solution to this\nproblem.\n\nSince `LOG` messages go to stderr, we decided to let googletest output go to\nstdout. This way, you can easily separate the two using redirection. For\nexample:\n\n```shell\n$ ./my_test > gtest_output.txt\n```\n\n## Why should I prefer test fixtures over global variables?\n\nThere are several good reasons:\n\n1. It's likely your test needs to change the states of its global variables.\n This makes it difficult to keep side effects from escaping one test and\n contaminating others, making debugging difficult. By using fixtures, each\n test has a fresh set of variables that's different (but with the same\n names). Thus, tests are kept independent of each other.\n2. Global variables pollute the global namespace.\n3. Test fixtures can be reused via subclassing, which cannot be done easily\n with global variables. This is useful if many test suites have something in\n common.\n\n## What can the statement argument in ASSERT_DEATH() be?\n\n`ASSERT_DEATH(statement, matcher)` (or any death assertion macro) can be used\nwherever *`statement`* is valid. So basically *`statement`* can be any C++\nstatement that makes sense in the current context. In particular, it can\nreference global and/or local variables, and can be:\n\n* a simple function call (often the case),\n* a complex expression, or\n* a compound statement.\n\nSome examples are shown here:\n\n```c++\n// A death test can be a simple function call.\nTEST(MyDeathTest, FunctionCall) {\n ASSERT_DEATH(Xyz(5), \"Xyz failed\");\n}\n\n// Or a complex expression that references variables and functions.\nTEST(MyDeathTest, ComplexExpression) {\n const bool c = Condition();\n ASSERT_DEATH((c ? Func1(0) : object2.Method(\"test\")),\n \"(Func1|Method) failed\");\n}\n\n// Death assertions can be used any where in a function. In\n// particular, they can be inside a loop.\nTEST(MyDeathTest, InsideLoop) {\n // Verifies that Foo(0), Foo(1), ..., and Foo(4) all die.\n for (int i = 0; i < 5; i++) {\n EXPECT_DEATH_M(Foo(i), \"Foo has \\\\d+ errors\",\n ::testing::Message() << \"where i is \" << i);\n }\n}\n\n// A death assertion can contain a compound statement.\nTEST(MyDeathTest, CompoundStatement) {\n // Verifies that at lease one of Bar(0), Bar(1), ..., and\n // Bar(4) dies.\n ASSERT_DEATH({\n for (int i = 0; i < 5; i++) {\n Bar(i);\n }\n },\n \"Bar has \\\\d+ errors\");\n}\n```\n\ngtest-death-test_test.cc contains more examples if you are interested.\n\n## I have a fixture class `FooTest`, but `TEST_F(FooTest, Bar)` gives me error ``\"no matching function for call to `FooTest::FooTest()'\"``. Why?\n\nGoogletest needs to be able to create objects of your test fixture class, so it\nmust have a default constructor. Normally the compiler will define one for you.\nHowever, there are cases where you have to define your own:\n\n* If you explicitly declare a non-default constructor for class `FooTest`\n (`DISALLOW_EVIL_CONSTRUCTORS()` does this), then you need to define a\n default constructor, even if it would be empty.\n* If `FooTest` has a const non-static data member, then you have to define the\n default constructor *and* initialize the const member in the initializer\n list of the constructor. (Early versions of `gcc` doesn't force you to\n initialize the const member. It's a bug that has been fixed in `gcc 4`.)\n\n## Why does ASSERT_DEATH complain about previous threads that were already joined?\n\nWith the Linux pthread library, there is no turning back once you cross the line\nfrom single thread to multiple threads. The first time you create a thread, a\nmanager thread is created in addition, so you get 3, not 2, threads. Later when\nthe thread you create joins the main thread, the thread count decrements by 1,\nbut the manager thread will never be killed, so you still have 2 threads, which\nmeans you cannot safely run a death test.\n\nThe new NPTL thread library doesn't suffer from this problem, as it doesn't\ncreate a manager thread. However, if you don't control which machine your test\nruns on, you shouldn't depend on this.\n\n## Why does googletest require the entire test suite, instead of individual tests, to be named *DeathTest when it uses ASSERT_DEATH?\n\ngoogletest does not interleave tests from different test suites. That is, it\nruns all tests in one test suite first, and then runs all tests in the next test\nsuite, and so on. googletest does this because it needs to set up a test suite\nbefore the first test in it is run, and tear it down afterwords. Splitting up\nthe test case would require multiple set-up and tear-down processes, which is\ninefficient and makes the semantics unclean.\n\nIf we were to determine the order of tests based on test name instead of test\ncase name, then we would have a problem with the following situation:\n\n```c++\nTEST_F(FooTest, AbcDeathTest) { ... }\nTEST_F(FooTest, Uvw) { ... }\n\nTEST_F(BarTest, DefDeathTest) { ... }\nTEST_F(BarTest, Xyz) { ... }\n```\n\nSince `FooTest.AbcDeathTest` needs to run before `BarTest.Xyz`, and we don't\ninterleave tests from different test suites, we need to run all tests in the\n`FooTest` case before running any test in the `BarTest` case. This contradicts\nwith the requirement to run `BarTest.DefDeathTest` before `FooTest.Uvw`.\n\n## But I don't like calling my entire test suite \\*DeathTest when it contains both death tests and non-death tests. What do I do?\n\nYou don't have to, but if you like, you may split up the test suite into\n`FooTest` and `FooDeathTest`, where the names make it clear that they are\nrelated:\n\n```c++\nclass FooTest : public ::testing::Test { ... };\n\nTEST_F(FooTest, Abc) { ... }\nTEST_F(FooTest, Def) { ... }\n\nusing FooDeathTest = FooTest;\n\nTEST_F(FooDeathTest, Uvw) { ... EXPECT_DEATH(...) ... }\nTEST_F(FooDeathTest, Xyz) { ... ASSERT_DEATH(...) ... }\n```\n\n## googletest prints the LOG messages in a death test's child process only when the test fails. How can I see the LOG messages when the death test succeeds?\n\nPrinting the LOG messages generated by the statement inside `EXPECT_DEATH()`\nmakes it harder to search for real problems in the parent's log. Therefore,\ngoogletest only prints them when the death test has failed.\n\nIf you really need to see such LOG messages, a workaround is to temporarily\nbreak the death test (e.g. by changing the regex pattern it is expected to\nmatch). Admittedly, this is a hack. We'll consider a more permanent solution\nafter the fork-and-exec-style death tests are implemented.\n\n## The compiler complains about \"no match for 'operator<<'\" when I use an assertion. What gives?\n\nIf you use a user-defined type `FooType` in an assertion, you must make sure\nthere is an `std::ostream& operator<<(std::ostream&, const FooType&)` function\ndefined such that we can print a value of `FooType`.\n\nIn addition, if `FooType` is declared in a name space, the `<<` operator also\nneeds to be defined in the *same* name space. See https://abseil.io/tips/49 for details.\n\n## How do I suppress the memory leak messages on Windows?\n\nSince the statically initialized googletest singleton requires allocations on\nthe heap, the Visual C++ memory leak detector will report memory leaks at the\nend of the program run. The easiest way to avoid this is to use the\n`_CrtMemCheckpoint` and `_CrtMemDumpAllObjectsSince` calls to not report any\nstatically initialized heap objects. See MSDN for more details and additional\nheap check/debug routines.\n\n## How can my code detect if it is running in a test?\n\nIf you write code that sniffs whether it's running in a test and does different\nthings accordingly, you are leaking test-only logic into production code and\nthere is no easy way to ensure that the test-only code paths aren't run by\nmistake in production. Such cleverness also leads to\n[Heisenbugs](https://en.wikipedia.org/wiki/Heisenbug). Therefore we strongly\nadvise against the practice, and googletest doesn't provide a way to do it.\n\nIn general, the recommended way to cause the code to behave differently under\ntest is [Dependency Injection](https://en.wikipedia.org/wiki/Dependency_injection). You can inject\ndifferent functionality from the test and from the production code. Since your\nproduction code doesn't link in the for-test logic at all (the\n[`testonly`](https://docs.bazel.build/versions/master/be/common-definitions.html#common.testonly) attribute for BUILD targets helps to ensure\nthat), there is no danger in accidentally running it.\n\nHowever, if you *really*, *really*, *really* have no choice, and if you follow\nthe rule of ending your test program names with `_test`, you can use the\n*horrible* hack of sniffing your executable name (`argv[0]` in `main()`) to know\nwhether the code is under test.\n\n## How do I temporarily disable a test?\n\nIf you have a broken test that you cannot fix right away, you can add the\nDISABLED_ prefix to its name. This will exclude it from execution. This is\nbetter than commenting out the code or using #if 0, as disabled tests are still\ncompiled (and thus won't rot).\n\nTo include disabled tests in test execution, just invoke the test program with\nthe --gtest_also_run_disabled_tests flag.\n\n## Is it OK if I have two separate `TEST(Foo, Bar)` test methods defined in different namespaces?\n\nYes.\n\nThe rule is **all test methods in the same test suite must use the same fixture\nclass.** This means that the following is **allowed** because both tests use the\nsame fixture class (`::testing::Test`).\n\n```c++\nnamespace foo {\nTEST(CoolTest, DoSomething) {\n SUCCEED();\n}\n} // namespace foo\n\nnamespace bar {\nTEST(CoolTest, DoSomething) {\n SUCCEED();\n}\n} // namespace bar\n```\n\nHowever, the following code is **not allowed** and will produce a runtime error\nfrom googletest because the test methods are using different test fixture\nclasses with the same test suite name.\n\n```c++\nnamespace foo {\nclass CoolTest : public ::testing::Test {}; // Fixture foo::CoolTest\nTEST_F(CoolTest, DoSomething) {\n SUCCEED();\n}\n} // namespace foo\n\nnamespace bar {\nclass CoolTest : public ::testing::Test {}; // Fixture: bar::CoolTest\nTEST_F(CoolTest, DoSomething) {\n SUCCEED();\n}\n} // namespace bar\n```\n" }, { "path": "test/googletest/docs/pkgconfig.md", "content": "## Using GoogleTest from various build systems\n\nGoogleTest comes with pkg-config files that can be used to determine all\nnecessary flags for compiling and linking to GoogleTest (and GoogleMock).\nPkg-config is a standardised plain-text format containing\n\n* the includedir (-I) path\n* necessary macro (-D) definitions\n* further required flags (-pthread)\n* the library (-L) path\n* the library (-l) to link to\n\nAll current build systems support pkg-config in one way or another. For all\nexamples here we assume you want to compile the sample\n`samples/sample3_unittest.cc`.\n\n### CMake\n\nUsing `pkg-config` in CMake is fairly easy:\n\n```cmake\ncmake_minimum_required(VERSION 3.0)\n\ncmake_policy(SET CMP0048 NEW)\nproject(my_gtest_pkgconfig VERSION 0.0.1 LANGUAGES CXX)\n\nfind_package(PkgConfig)\npkg_search_module(GTEST REQUIRED gtest_main)\n\nadd_executable(testapp samples/sample3_unittest.cc)\ntarget_link_libraries(testapp ${GTEST_LDFLAGS})\ntarget_compile_options(testapp PUBLIC ${GTEST_CFLAGS})\n\ninclude(CTest)\nadd_test(first_and_only_test testapp)\n```\n\nIt is generally recommended that you use `target_compile_options` + `_CFLAGS`\nover `target_include_directories` + `_INCLUDE_DIRS` as the former includes not\njust -I flags (GoogleTest might require a macro indicating to internal headers\nthat all libraries have been compiled with threading enabled. In addition,\nGoogleTest might also require `-pthread` in the compiling step, and as such\nsplitting the pkg-config `Cflags` variable into include dirs and macros for\n`target_compile_definitions()` might still miss this). The same recommendation\ngoes for using `_LDFLAGS` over the more commonplace `_LIBRARIES`, which happens\nto discard `-L` flags and `-pthread`.\n\n### Autotools\n\nFinding GoogleTest in Autoconf and using it from Automake is also fairly easy:\n\nIn your `configure.ac`:\n\n```\nAC_PREREQ([2.69])\nAC_INIT([my_gtest_pkgconfig], [0.0.1])\nAC_CONFIG_SRCDIR([samples/sample3_unittest.cc])\nAC_PROG_CXX\n\nPKG_CHECK_MODULES([GTEST], [gtest_main])\n\nAM_INIT_AUTOMAKE([foreign subdir-objects])\nAC_CONFIG_FILES([Makefile])\nAC_OUTPUT\n```\n\nand in your `Makefile.am`:\n\n```\ncheck_PROGRAMS = testapp\nTESTS = $(check_PROGRAMS)\n\ntestapp_SOURCES = samples/sample3_unittest.cc\ntestapp_CXXFLAGS = $(GTEST_CFLAGS)\ntestapp_LDADD = $(GTEST_LIBS)\n```\n\n### Meson\n\nMeson natively uses pkgconfig to query dependencies:\n\n```\nproject('my_gtest_pkgconfig', 'cpp', version : '0.0.1')\n\ngtest_dep = dependency('gtest_main')\n\ntestapp = executable(\n 'testapp',\n files(['samples/sample3_unittest.cc']),\n dependencies : gtest_dep,\n install : false)\n\ntest('first_and_only_test', testapp)\n```\n\n### Plain Makefiles\n\nSince `pkg-config` is a small Unix command-line utility, it can be used in\nhandwritten `Makefile`s too:\n\n```makefile\nGTEST_CFLAGS = `pkg-config --cflags gtest_main`\nGTEST_LIBS = `pkg-config --libs gtest_main`\n\n.PHONY: tests all\n\ntests: all\n ./testapp\n\nall: testapp\n\ntestapp: testapp.o\n $(CXX) $(CXXFLAGS) $(LDFLAGS) $< -o $@ $(GTEST_LIBS)\n\ntestapp.o: samples/sample3_unittest.cc\n $(CXX) $(CPPFLAGS) $(CXXFLAGS) $< -c -o $@ $(GTEST_CFLAGS)\n```\n\n### Help! pkg-config can't find GoogleTest!\n\nLet's say you have a `CMakeLists.txt` along the lines of the one in this\ntutorial and you try to run `cmake`. It is very possible that you get a failure\nalong the lines of:\n\n```\n-- Checking for one of the modules 'gtest_main'\nCMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:640 (message):\n None of the required 'gtest_main' found\n```\n\nThese failures are common if you installed GoogleTest yourself and have not\nsourced it from a distro or other package manager. If so, you need to tell\npkg-config where it can find the `.pc` files containing the information. Say you\ninstalled GoogleTest to `/usr/local`, then it might be that the `.pc` files are\ninstalled under `/usr/local/lib64/pkgconfig`. If you set\n\n```\nexport PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig\n```\n\npkg-config will also try to look in `PKG_CONFIG_PATH` to find `gtest_main.pc`.\n\n### Using pkg-config in a cross-compilation setting\n\nPkg-config can be used in a cross-compilation setting too. To do this, let's\nassume the final prefix of the cross-compiled installation will be `/usr`, and\nyour sysroot is `/home/MYUSER/sysroot`. Configure and install GTest using\n\n```\nmkdir build && cmake -DCMAKE_INSTALL_PREFIX=/usr ..\n```\n\nInstall into the sysroot using `DESTDIR`:\n\n```\nmake -j install DESTDIR=/home/MYUSER/sysroot\n```\n\nBefore we continue, it is recommended to **always** define the following two\nvariables for pkg-config in a cross-compilation setting:\n\n```\nexport PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=yes\nexport PKG_CONFIG_ALLOW_SYSTEM_LIBS=yes\n```\n\notherwise `pkg-config` will filter `-I` and `-L` flags against standard prefixes\nsuch as `/usr` (see https://bugs.freedesktop.org/show_bug.cgi?id=28264#c3 for\nreasons why this stripping needs to occur usually).\n\nIf you look at the generated pkg-config file, it will look something like\n\n```\nlibdir=/usr/lib64\nincludedir=/usr/include\n\nName: gtest\nDescription: GoogleTest (without main() function)\nVersion: 1.10.0\nURL: https://github.com/google/googletest\nLibs: -L${libdir} -lgtest -lpthread\nCflags: -I${includedir} -DGTEST_HAS_PTHREAD=1 -lpthread\n```\n\nNotice that the sysroot is not included in `libdir` and `includedir`! If you try\nto run `pkg-config` with the correct\n`PKG_CONFIG_LIBDIR=/home/MYUSER/sysroot/usr/lib64/pkgconfig` against this `.pc`\nfile, you will get\n\n```\n$ pkg-config --cflags gtest\n-DGTEST_HAS_PTHREAD=1 -lpthread -I/usr/include\n$ pkg-config --libs gtest\n-L/usr/lib64 -lgtest -lpthread\n```\n\nwhich is obviously wrong and points to the `CBUILD` and not `CHOST` root. In\norder to use this in a cross-compilation setting, we need to tell pkg-config to\ninject the actual sysroot into `-I` and `-L` variables. Let us now tell\npkg-config about the actual sysroot\n\n```\nexport PKG_CONFIG_DIR=\nexport PKG_CONFIG_SYSROOT_DIR=/home/MYUSER/sysroot\nexport PKG_CONFIG_LIBDIR=${PKG_CONFIG_SYSROOT_DIR}/usr/lib64/pkgconfig\n```\n\nand running `pkg-config` again we get\n\n```\n$ pkg-config --cflags gtest\n-DGTEST_HAS_PTHREAD=1 -lpthread -I/home/MYUSER/sysroot/usr/include\n$ pkg-config --libs gtest\n-L/home/MYUSER/sysroot/usr/lib64 -lgtest -lpthread\n```\n\nwhich contains the correct sysroot now. For a more comprehensive guide to also\nincluding `${CHOST}` in build system calls, see the excellent tutorial by Diego\nElio Pettenò: https://autotools.io/pkgconfig/cross-compiling.html\n" }, { "path": "test/googletest/docs/primer.md", "content": "# Googletest Primer\n\n## Introduction: Why googletest?\n\n*googletest* helps you write better C++ tests.\n\ngoogletest is a testing framework developed by the Testing Technology team with\nGoogle's specific requirements and constraints in mind. Whether you work on\nLinux, Windows, or a Mac, if you write C++ code, googletest can help you. And it\nsupports *any* kind of tests, not just unit tests.\n\nSo what makes a good test, and how does googletest fit in? We believe:\n\n1. Tests should be *independent* and *repeatable*. It's a pain to debug a test\n that succeeds or fails as a result of other tests. googletest isolates the\n tests by running each of them on a different object. When a test fails,\n googletest allows you to run it in isolation for quick debugging.\n2. Tests should be well *organized* and reflect the structure of the tested\n code. googletest groups related tests into test suites that can share data\n and subroutines. This common pattern is easy to recognize and makes tests\n easy to maintain. Such consistency is especially helpful when people switch\n projects and start to work on a new code base.\n3. Tests should be *portable* and *reusable*. Google has a lot of code that is\n platform-neutral; its tests should also be platform-neutral. googletest\n works on different OSes, with different compilers, with or without\n exceptions, so googletest tests can work with a variety of configurations.\n4. When tests fail, they should provide as much *information* about the problem\n as possible. googletest doesn't stop at the first test failure. Instead, it\n only stops the current test and continues with the next. You can also set up\n tests that report non-fatal failures after which the current test continues.\n Thus, you can detect and fix multiple bugs in a single run-edit-compile\n cycle.\n5. The testing framework should liberate test writers from housekeeping chores\n and let them focus on the test *content*. googletest automatically keeps\n track of all tests defined, and doesn't require the user to enumerate them\n in order to run them.\n6. Tests should be *fast*. With googletest, you can reuse shared resources\n across tests and pay for the set-up/tear-down only once, without making\n tests depend on each other.\n\nSince googletest is based on the popular xUnit architecture, you'll feel right\nat home if you've used JUnit or PyUnit before. If not, it will take you about 10\nminutes to learn the basics and get started. So let's go!\n\n## Beware of the nomenclature\n\n_Note:_ There might be some confusion arising from different definitions of the\nterms _Test_, _Test Case_ and _Test Suite_, so beware of misunderstanding these.\n\nHistorically, googletest started to use the term _Test Case_ for grouping\nrelated tests, whereas current publications, including International Software\nTesting Qualifications Board ([ISTQB](http://www.istqb.org/)) materials and\nvarious textbooks on software quality, use the term\n_[Test Suite][istqb test suite]_ for this.\n\nThe related term _Test_, as it is used in googletest, corresponds to the term\n_[Test Case][istqb test case]_ of ISTQB and others.\n\nThe term _Test_ is commonly of broad enough sense, including ISTQB's definition\nof _Test Case_, so it's not much of a problem here. But the term _Test Case_ as\nwas used in Google Test is of contradictory sense and thus confusing.\n\ngoogletest recently started replacing the term _Test Case_ with _Test Suite_.\nThe preferred API is *TestSuite*. The older TestCase API is being slowly\ndeprecated and refactored away.\n\nSo please be aware of the different definitions of the terms:\n\n\n\nMeaning | googletest Term | [ISTQB](http://www.istqb.org/) Term\n:----------------------------------------------------------------------------------- | :---------------------- | :----------------------------------\nExercise a particular program path with specific input values and verify the results | [TEST()](#simple-tests) | [Test Case][istqb test case]\n\n\n\n[istqb test case]: http://glossary.istqb.org/en/search/test%20case\n[istqb test suite]: http://glossary.istqb.org/en/search/test%20suite\n\n## Basic Concepts\n\nWhen using googletest, you start by writing *assertions*, which are statements\nthat check whether a condition is true. An assertion's result can be *success*,\n*nonfatal failure*, or *fatal failure*. If a fatal failure occurs, it aborts the\ncurrent function; otherwise the program continues normally.\n\n*Tests* use assertions to verify the tested code's behavior. If a test crashes\nor has a failed assertion, then it *fails*; otherwise it *succeeds*.\n\nA *test suite* contains one or many tests. You should group your tests into test\nsuites that reflect the structure of the tested code. When multiple tests in a\ntest suite need to share common objects and subroutines, you can put them into a\n*test fixture* class.\n\nA *test program* can contain multiple test suites.\n\nWe'll now explain how to write a test program, starting at the individual\nassertion level and building up to tests and test suites.\n\n## Assertions\n\ngoogletest assertions are macros that resemble function calls. You test a class\nor function by making assertions about its behavior. When an assertion fails,\ngoogletest prints the assertion's source file and line number location, along\nwith a failure message. You may also supply a custom failure message which will\nbe appended to googletest's message.\n\nThe assertions come in pairs that test the same thing but have different effects\non the current function. `ASSERT_*` versions generate fatal failures when they\nfail, and **abort the current function**. `EXPECT_*` versions generate nonfatal\nfailures, which don't abort the current function. Usually `EXPECT_*` are\npreferred, as they allow more than one failure to be reported in a test.\nHowever, you should use `ASSERT_*` if it doesn't make sense to continue when the\nassertion in question fails.\n\nSince a failed `ASSERT_*` returns from the current function immediately,\npossibly skipping clean-up code that comes after it, it may cause a space leak.\nDepending on the nature of the leak, it may or may not be worth fixing - so keep\nthis in mind if you get a heap checker error in addition to assertion errors.\n\nTo provide a custom failure message, simply stream it into the macro using the\n`<<` operator or a sequence of such operators. An example:\n\n```c++\nASSERT_EQ(x.size(), y.size()) << \"Vectors x and y are of unequal length\";\n\nfor (int i = 0; i < x.size(); ++i) {\n EXPECT_EQ(x[i], y[i]) << \"Vectors x and y differ at index \" << i;\n}\n```\n\nAnything that can be streamed to an `ostream` can be streamed to an assertion\nmacro--in particular, C strings and `string` objects. If a wide string\n(`wchar_t*`, `TCHAR*` in `UNICODE` mode on Windows, or `std::wstring`) is\nstreamed to an assertion, it will be translated to UTF-8 when printed.\n\n### Basic Assertions\n\nThese assertions do basic true/false condition testing.\n\nFatal assertion | Nonfatal assertion | Verifies\n-------------------------- | -------------------------- | --------------------\n`ASSERT_TRUE(condition);` | `EXPECT_TRUE(condition);` | `condition` is true\n`ASSERT_FALSE(condition);` | `EXPECT_FALSE(condition);` | `condition` is false\n\nRemember, when they fail, `ASSERT_*` yields a fatal failure and returns from the\ncurrent function, while `EXPECT_*` yields a nonfatal failure, allowing the\nfunction to continue running. In either case, an assertion failure means its\ncontaining test fails.\n\n**Availability**: Linux, Windows, Mac.\n\n### Binary Comparison\n\nThis section describes assertions that compare two values.\n\nFatal assertion | Nonfatal assertion | Verifies\n------------------------ | ------------------------ | --------------\n`ASSERT_EQ(val1, val2);` | `EXPECT_EQ(val1, val2);` | `val1 == val2`\n`ASSERT_NE(val1, val2);` | `EXPECT_NE(val1, val2);` | `val1 != val2`\n`ASSERT_LT(val1, val2);` | `EXPECT_LT(val1, val2);` | `val1 < val2`\n`ASSERT_LE(val1, val2);` | `EXPECT_LE(val1, val2);` | `val1 <= val2`\n`ASSERT_GT(val1, val2);` | `EXPECT_GT(val1, val2);` | `val1 > val2`\n`ASSERT_GE(val1, val2);` | `EXPECT_GE(val1, val2);` | `val1 >= val2`\n\nValue arguments must be comparable by the assertion's comparison operator or\nyou'll get a compiler error. We used to require the arguments to support the\n`<<` operator for streaming to an `ostream`, but this is no longer necessary. If\n`<<` is supported, it will be called to print the arguments when the assertion\nfails; otherwise googletest will attempt to print them in the best way it can.\nFor more details and how to customize the printing of the arguments, see the\n[documentation](../../googlemock/docs/cook_book.md#teaching-gmock-how-to-print-your-values).\n\nThese assertions can work with a user-defined type, but only if you define the\ncorresponding comparison operator (e.g., `==` or `<`). Since this is discouraged\nby the Google\n[C++ Style Guide](https://google.github.io/styleguide/cppguide.html#Operator_Overloading),\nyou may need to use `ASSERT_TRUE()` or `EXPECT_TRUE()` to assert the equality of\ntwo objects of a user-defined type.\n\nHowever, when possible, `ASSERT_EQ(actual, expected)` is preferred to\n`ASSERT_TRUE(actual == expected)`, since it tells you `actual` and `expected`'s\nvalues on failure.\n\nArguments are always evaluated exactly once. Therefore, it's OK for the\narguments to have side effects. However, as with any ordinary C/C++ function,\nthe arguments' evaluation order is undefined (i.e., the compiler is free to\nchoose any order), and your code should not depend on any particular argument\nevaluation order.\n\n`ASSERT_EQ()` does pointer equality on pointers. If used on two C strings, it\ntests if they are in the same memory location, not if they have the same value.\nTherefore, if you want to compare C strings (e.g. `const char*`) by value, use\n`ASSERT_STREQ()`, which will be described later on. In particular, to assert\nthat a C string is `NULL`, use `ASSERT_STREQ(c_string, NULL)`. Consider using\n`ASSERT_EQ(c_string, nullptr)` if c++11 is supported. To compare two `string`\nobjects, you should use `ASSERT_EQ`.\n\nWhen doing pointer comparisons use `*_EQ(ptr, nullptr)` and `*_NE(ptr, nullptr)`\ninstead of `*_EQ(ptr, NULL)` and `*_NE(ptr, NULL)`. This is because `nullptr` is\ntyped, while `NULL` is not. See the [FAQ](faq.md) for more details.\n\nIf you're working with floating point numbers, you may want to use the floating\npoint variations of some of these macros in order to avoid problems caused by\nrounding. See [Advanced googletest Topics](advanced.md) for details.\n\nMacros in this section work with both narrow and wide string objects (`string`\nand `wstring`).\n\n**Availability**: Linux, Windows, Mac.\n\n**Historical note**: Before February 2016 `*_EQ` had a convention of calling it\nas `ASSERT_EQ(expected, actual)`, so lots of existing code uses this order. Now\n`*_EQ` treats both parameters in the same way.\n\n### String Comparison\n\nThe assertions in this group compare two **C strings**. If you want to compare\ntwo `string` objects, use `EXPECT_EQ`, `EXPECT_NE`, and etc instead.\n\n\n\n| Fatal assertion | Nonfatal assertion | Verifies |\n| -------------------------- | ------------------------------ | -------------------------------------------------------- |\n| `ASSERT_STREQ(str1,str2);` | `EXPECT_STREQ(str1,str2);` | the two C strings have the same content \t\t |\n| `ASSERT_STRNE(str1,str2);` | `EXPECT_STRNE(str1,str2);` | the two C strings have different contents \t\t |\n| `ASSERT_STRCASEEQ(str1,str2);` | `EXPECT_STRCASEEQ(str1,str2);` | the two C strings have the same content, ignoring case |\n| `ASSERT_STRCASENE(str1,str2);` | `EXPECT_STRCASENE(str1,str2);` | the two C strings have different contents, ignoring case |\n\n\n\nNote that \"CASE\" in an assertion name means that case is ignored. A `NULL`\npointer and an empty string are considered *different*.\n\n`*STREQ*` and `*STRNE*` also accept wide C strings (`wchar_t*`). If a comparison\nof two wide strings fails, their values will be printed as UTF-8 narrow strings.\n\n**Availability**: Linux, Windows, Mac.\n\n**See also**: For more string comparison tricks (substring, prefix, suffix, and\nregular expression matching, for example), see [this](advanced.md) in the\nAdvanced googletest Guide.\n\n## Simple Tests\n\nTo create a test:\n\n1. Use the `TEST()` macro to define and name a test function. These are\n ordinary C++ functions that don't return a value.\n2. In this function, along with any valid C++ statements you want to include,\n use the various googletest assertions to check values.\n3. The test's result is determined by the assertions; if any assertion in the\n test fails (either fatally or non-fatally), or if the test crashes, the\n entire test fails. Otherwise, it succeeds.\n\n```c++\nTEST(TestSuiteName, TestName) {\n ... test body ...\n}\n```\n\n`TEST()` arguments go from general to specific. The *first* argument is the name\nof the test suite, and the *second* argument is the test's name within the test\ncase. Both names must be valid C++ identifiers, and they should not contain\nany underscores (`_`). A test's *full name* consists of its containing test suite and\nits individual name. Tests from different test suites can have the same\nindividual name.\n\nFor example, let's take a simple integer function:\n\n```c++\nint Factorial(int n); // Returns the factorial of n\n```\n\nA test suite for this function might look like:\n\n```c++\n// Tests factorial of 0.\nTEST(FactorialTest, HandlesZeroInput) {\n EXPECT_EQ(Factorial(0), 1);\n}\n\n// Tests factorial of positive numbers.\nTEST(FactorialTest, HandlesPositiveInput) {\n EXPECT_EQ(Factorial(1), 1);\n EXPECT_EQ(Factorial(2), 2);\n EXPECT_EQ(Factorial(3), 6);\n EXPECT_EQ(Factorial(8), 40320);\n}\n```\n\ngoogletest groups the test results by test suites, so logically related tests\nshould be in the same test suite; in other words, the first argument to their\n`TEST()` should be the same. In the above example, we have two tests,\n`HandlesZeroInput` and `HandlesPositiveInput`, that belong to the same test\nsuite `FactorialTest`.\n\nWhen naming your test suites and tests, you should follow the same convention as\nfor\n[naming functions and classes](https://google.github.io/styleguide/cppguide.html#Function_Names).\n\n**Availability**: Linux, Windows, Mac.\n\n## Test Fixtures: Using the Same Data Configuration for Multiple Tests {#same-data-multiple-tests}\n\nIf you find yourself writing two or more tests that operate on similar data, you\ncan use a *test fixture*. This allows you to reuse the same configuration of\nobjects for several different tests.\n\nTo create a fixture:\n\n1. Derive a class from `::testing::Test` . Start its body with `protected:`, as\n we'll want to access fixture members from sub-classes.\n2. Inside the class, declare any objects you plan to use.\n3. If necessary, write a default constructor or `SetUp()` function to prepare\n the objects for each test. A common mistake is to spell `SetUp()` as\n **`Setup()`** with a small `u` - Use `override` in C++11 to make sure you\n spelled it correctly.\n4. If necessary, write a destructor or `TearDown()` function to release any\n resources you allocated in `SetUp()` . To learn when you should use the\n constructor/destructor and when you should use `SetUp()/TearDown()`, read\n the [FAQ](faq.md#CtorVsSetUp).\n5. If needed, define subroutines for your tests to share.\n\nWhen using a fixture, use `TEST_F()` instead of `TEST()` as it allows you to\naccess objects and subroutines in the test fixture:\n\n```c++\nTEST_F(TestFixtureName, TestName) {\n ... test body ...\n}\n```\n\nLike `TEST()`, the first argument is the test suite name, but for `TEST_F()`\nthis must be the name of the test fixture class. You've probably guessed: `_F`\nis for fixture.\n\nUnfortunately, the C++ macro system does not allow us to create a single macro\nthat can handle both types of tests. Using the wrong macro causes a compiler\nerror.\n\nAlso, you must first define a test fixture class before using it in a\n`TEST_F()`, or you'll get the compiler error \"`virtual outside class\ndeclaration`\".\n\nFor each test defined with `TEST_F()`, googletest will create a *fresh* test\nfixture at runtime, immediately initialize it via `SetUp()`, run the test,\nclean up by calling `TearDown()`, and then delete the test fixture. Note that\ndifferent tests in the same test suite have different test fixture objects, and\ngoogletest always deletes a test fixture before it creates the next one.\ngoogletest does **not** reuse the same test fixture for multiple tests. Any\nchanges one test makes to the fixture do not affect other tests.\n\nAs an example, let's write tests for a FIFO queue class named `Queue`, which has\nthe following interface:\n\n```c++\ntemplate // E is the element type.\nclass Queue {\n public:\n Queue();\n void Enqueue(const E& element);\n E* Dequeue(); // Returns NULL if the queue is empty.\n size_t size() const;\n ...\n};\n```\n\nFirst, define a fixture class. By convention, you should give it the name\n`FooTest` where `Foo` is the class being tested.\n\n```c++\nclass QueueTest : public ::testing::Test {\n protected:\n void SetUp() override {\n q1_.Enqueue(1);\n q2_.Enqueue(2);\n q2_.Enqueue(3);\n }\n\n // void TearDown() override {}\n\n Queue q0_;\n Queue q1_;\n Queue q2_;\n};\n```\n\nIn this case, `TearDown()` is not needed since we don't have to clean up after\neach test, other than what's already done by the destructor.\n\nNow we'll write tests using `TEST_F()` and this fixture.\n\n```c++\nTEST_F(QueueTest, IsEmptyInitially) {\n EXPECT_EQ(q0_.size(), 0);\n}\n\nTEST_F(QueueTest, DequeueWorks) {\n int* n = q0_.Dequeue();\n EXPECT_EQ(n, nullptr);\n\n n = q1_.Dequeue();\n ASSERT_NE(n, nullptr);\n EXPECT_EQ(*n, 1);\n EXPECT_EQ(q1_.size(), 0);\n delete n;\n\n n = q2_.Dequeue();\n ASSERT_NE(n, nullptr);\n EXPECT_EQ(*n, 2);\n EXPECT_EQ(q2_.size(), 1);\n delete n;\n}\n```\n\nThe above uses both `ASSERT_*` and `EXPECT_*` assertions. The rule of thumb is\nto use `EXPECT_*` when you want the test to continue to reveal more errors after\nthe assertion failure, and use `ASSERT_*` when continuing after failure doesn't\nmake sense. For example, the second assertion in the `Dequeue` test is\n`ASSERT_NE(nullptr, n)`, as we need to dereference the pointer `n` later, which\nwould lead to a segfault when `n` is `NULL`.\n\nWhen these tests run, the following happens:\n\n1. googletest constructs a `QueueTest` object (let's call it `t1`).\n2. `t1.SetUp()` initializes `t1`.\n3. The first test (`IsEmptyInitially`) runs on `t1`.\n4. `t1.TearDown()` cleans up after the test finishes.\n5. `t1` is destructed.\n6. The above steps are repeated on another `QueueTest` object, this time\n running the `DequeueWorks` test.\n\n**Availability**: Linux, Windows, Mac.\n\n## Invoking the Tests\n\n`TEST()` and `TEST_F()` implicitly register their tests with googletest. So,\nunlike with many other C++ testing frameworks, you don't have to re-list all\nyour defined tests in order to run them.\n\nAfter defining your tests, you can run them with `RUN_ALL_TESTS()`, which\nreturns `0` if all the tests are successful, or `1` otherwise. Note that\n`RUN_ALL_TESTS()` runs *all tests* in your link unit--they can be from\ndifferent test suites, or even different source files.\n\nWhen invoked, the `RUN_ALL_TESTS()` macro:\n\n* Saves the state of all googletest flags.\n\n* Creates a test fixture object for the first test.\n\n* Initializes it via `SetUp()`.\n\n* Runs the test on the fixture object.\n\n* Cleans up the fixture via `TearDown()`.\n\n* Deletes the fixture.\n\n* Restores the state of all googletest flags.\n\n* Repeats the above steps for the next test, until all tests have run.\n\nIf a fatal failure happens the subsequent steps will be skipped.\n\n> IMPORTANT: You must **not** ignore the return value of `RUN_ALL_TESTS()`, or\n> you will get a compiler error. The rationale for this design is that the\n> automated testing service determines whether a test has passed based on its\n> exit code, not on its stdout/stderr output; thus your `main()` function must\n> return the value of `RUN_ALL_TESTS()`.\n>\n> Also, you should call `RUN_ALL_TESTS()` only **once**. Calling it more than\n> once conflicts with some advanced googletest features (e.g., thread-safe\n> [death tests](advanced.md#death-tests)) and thus is not supported.\n\n**Availability**: Linux, Windows, Mac.\n\n## Writing the main() Function\n\nMost users should _not_ need to write their own `main` function and instead link\nwith `gtest_main` (as opposed to with `gtest`), which defines a suitable entry\npoint. See the end of this section for details. The remainder of this section\nshould only apply when you need to do something custom before the tests run that\ncannot be expressed within the framework of fixtures and test suites.\n\nIf you write your own `main` function, it should return the value of\n`RUN_ALL_TESTS()`.\n\nYou can start from this boilerplate:\n\n```c++\n#include \"this/package/foo.h\"\n\n#include \"gtest/gtest.h\"\n\nnamespace my {\nnamespace project {\nnamespace {\n\n// The fixture for testing class Foo.\nclass FooTest : public ::testing::Test {\n protected:\n // You can remove any or all of the following functions if their bodies would\n // be empty.\n\n FooTest() {\n // You can do set-up work for each test here.\n }\n\n ~FooTest() override {\n // You can do clean-up work that doesn't throw exceptions here.\n }\n\n // If the constructor and destructor are not enough for setting up\n // and cleaning up each test, you can define the following methods:\n\n void SetUp() override {\n // Code here will be called immediately after the constructor (right\n // before each test).\n }\n\n void TearDown() override {\n // Code here will be called immediately after each test (right\n // before the destructor).\n }\n\n // Class members declared here can be used by all tests in the test suite\n // for Foo.\n};\n\n// Tests that the Foo::Bar() method does Abc.\nTEST_F(FooTest, MethodBarDoesAbc) {\n const std::string input_filepath = \"this/package/testdata/myinputfile.dat\";\n const std::string output_filepath = \"this/package/testdata/myoutputfile.dat\";\n Foo f;\n EXPECT_EQ(f.Bar(input_filepath, output_filepath), 0);\n}\n\n// Tests that Foo does Xyz.\nTEST_F(FooTest, DoesXyz) {\n // Exercises the Xyz feature of Foo.\n}\n\n} // namespace\n} // namespace project\n} // namespace my\n\nint main(int argc, char **argv) {\n ::testing::InitGoogleTest(&argc, argv);\n return RUN_ALL_TESTS();\n}\n```\n\nThe `::testing::InitGoogleTest()` function parses the command line for\ngoogletest flags, and removes all recognized flags. This allows the user to\ncontrol a test program's behavior via various flags, which we'll cover in\nthe [AdvancedGuide](advanced.md). You **must** call this function before calling\n`RUN_ALL_TESTS()`, or the flags won't be properly initialized.\n\nOn Windows, `InitGoogleTest()` also works with wide strings, so it can be used\nin programs compiled in `UNICODE` mode as well.\n\nBut maybe you think that writing all those `main` functions is too much work? We\nagree with you completely, and that's why Google Test provides a basic\nimplementation of main(). If it fits your needs, then just link your test with\nthe `gtest_main` library and you are good to go.\n\nNOTE: `ParseGUnitFlags()` is deprecated in favor of `InitGoogleTest()`.\n\n## Known Limitations\n\n* Google Test is designed to be thread-safe. The implementation is thread-safe\n on systems where the `pthreads` library is available. It is currently\n _unsafe_ to use Google Test assertions from two threads concurrently on\n other systems (e.g. Windows). In most tests this is not an issue as usually\n the assertions are done in the main thread. If you want to help, you can\n volunteer to implement the necessary synchronization primitives in\n `gtest-port.h` for your platform.\n" }, { "path": "test/googletest/docs/samples.md", "content": "# Googletest Samples {#samples}\n\nIf you're like us, you'd like to look at\n[googletest samples.](https://github.com/google/googletest/tree/master/googletest/samples)\nThe sample directory has a number of well-commented samples showing how to use a\nvariety of googletest features.\n\n* Sample #1 shows the basic steps of using googletest to test C++ functions.\n* Sample #2 shows a more complex unit test for a class with multiple member\n functions.\n* Sample #3 uses a test fixture.\n* Sample #4 teaches you how to use googletest and `googletest.h` together to\n get the best of both libraries.\n* Sample #5 puts shared testing logic in a base test fixture, and reuses it in\n derived fixtures.\n* Sample #6 demonstrates type-parameterized tests.\n* Sample #7 teaches the basics of value-parameterized tests.\n* Sample #8 shows using `Combine()` in value-parameterized tests.\n* Sample #9 shows use of the listener API to modify Google Test's console\n output and the use of its reflection API to inspect test results.\n* Sample #10 shows use of the listener API to implement a primitive memory\n leak checker.\n" }, { "path": "test/googletest/include/gtest/gtest-death-test.h", "content": "// Copyright 2005, Google Inc.\n// All rights reserved.\n//\n// Redistribution and use in source and binary forms, with or without\n// modification, are permitted provided that the following conditions are\n// met:\n//\n// * Redistributions of source code must retain the above copyright\n// notice, this list of conditions and the following disclaimer.\n// * Redistributions in binary form must reproduce the above\n// copyright notice, this list of conditions and the following disclaimer\n// in the documentation and/or other materials provided with the\n// distribution.\n// * Neither the name of Google Inc. nor the names of its\n// contributors may be used to endorse or promote products derived from\n// this software without specific prior written permission.\n//\n// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS\n// \"AS IS\" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT\n// LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR\n// A PARTICULAR PURPOSE ARE DISCLAIMED.

The parent process waits for the sub-process to terminate.\n//\n// 4. The parent process checks the exit code and error message of\n// the sub-process.\n//\n// Examples:\n//\n// ASSERT_DEATH(server.SendMessage(56, \"Hello\"), \"Invalid port number\");\n// for (int i = 0; i < 5; i++) {\n// EXPECT_DEATH(server.ProcessRequest(i),\n// \"Invalid request .* in ProcessRequest()\")\n// << \"Failed to die on request \" << i;\n// }\n//\n// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), \"Exiting\");\n//\n// bool KilledBySIGHUP(int exit_code) {\n// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;\n// }\n//\n// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, \"Hanging up!\");\n//\n// On the regular expressions used in death tests:\n//\n// GOOGLETEST_CM0005 DO NOT DELETE\n// On POSIX-compliant systems (*nix), we use the library,\n// which uses the POSIX extended regex syntax.\n//\n// On other platforms (e.g. Windows or Mac), we only support a simple regex\n// syntax implemented as part of Google Test. This limited\n// implementation should be enough most of the time when writing\n// death tests; though it lacks many features you can find in PCRE\n// or POSIX extended regex syntax. For example, we don't support\n// union (\"x|y\"), grouping (\"(xy)\"), brackets (\"[xy]\"), and\n// repetition count (\"x{5,7}\"), among others.\n//\n// Below is the syntax that we do support. We chose it to be a\n// subset of both PCRE and POSIX extended regex, so it's easy to\n// learn wherever you come from. In the following: 'A' denotes a\n// literal character, period (.), or a single \\\\ escape sequence;\n// 'x' and 'y' denote regular expressions; 'm' and 'n' are for\n// natural numbers.\n//\n// c matches any literal character c\n// \\\\d matches any decimal digit\n// \\\\D matches any character that's not a decimal digit\n// \\\\f matches \\f\n// \\\\n matches \\n\n// \\\\r matches \\r\n// \\\\s matches any ASCII whitespace, including \\n\n// \\\\S matches any character that's not a whitespace\n// \\\\t matches \\t\n// \\\\v matches \\v\n// \\\\w matches any letter, _, or decimal digit\n// \\\\W matches any character that \\\\w doesn't match\n// \\\\c matches any literal character c, which must be a punctuation\n// . matches any single character except \\n\n// A? matches 0 or 1 occurrences of A\n// A* matches 0 or many occurrences of A\n// A+ matches 1 or many occurrences of A\n// ^ matches the beginning of a string (not that of each line)\n// $ matches the end of a string (not that of each line)\n// xy matches x followed by y\n//\n// If you accidentally use PCRE or POSIX extended regex features\n// not implemented by us, you will get a run-time failure. In that\n// case, please try to rewrite your regular expression within the\n// above syntax.\n//\n// This implementation is *not* meant to be as highly tuned or robust\n// as a compiled regex library, but should perform well enough for a\n// death test, which already incurs significant overhead by launching\n// a child process.\n//\n// Known caveats:\n//\n// A \"threadsafe\" style death test obtains the path to the test\n// program from argv[0] and re-executes it in the sub-process. For\n// simplicity, the current implementation doesn't search the PATH\n// when launching the sub-process. This means that the user must\n// invoke the test program via a path that contains at least one\n// path separator (e.g. path/to/foo_test and\n// /absolute/path/to/bar_test are fine, but foo_test is not).

After this header is #included, all\n// macros in this list will be defined to either 1 or 0.\n//\n// Notes to maintainers:\n// - Each macro here is a user-tweakable knob; do not grow the list\n// lightly.\n// - Use #if to key off these macros.

When we release a new version of\n Google Test or Google Mock, we need to branch the wiki files\n such that users of a specific version of Google Test/Mock can\n look up documenation relevant for that version. This script\n automates that process by:\n\n - branching the current wiki pages (which document the\n behavior of the SVN trunk head) to pages for the specified\n version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when\n NEW_RELEASE_VERSION is 2.6);\n - updating the links in the branched files to point to the branched\n version (e.g. a link in V2_6_FAQ.wiki that pointed to\n Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).\n\n NOTE: NEW_RELEASE_VERSION must be a NEW version number for\n which the wiki pages don't yet exist; otherwise you'll get SVN\n errors like \"svn: Path 'V1_7_PumpManual.wiki' is not a\n directory\" when running the script.\n\nEXAMPLE\n $ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk\n $ scripts/release_docs.py 2.6 # create wiki pages for v2.6\n $ svn status # verify the file list\n $ svn diff # verify the file contents\n $ svn commit -m \"release wiki pages for v2.6\"\n\"\"\"\n\n__author__ = 'wan@google.com (Zhanyong Wan)'\n\nimport os\nimport re\nimport sys\n\nimport common\n\n\n# Wiki pages that shouldn't be branched for every gtest/gmock release.\nGTEST_UNVERSIONED_WIKIS = ['DevGuide.wiki']\nGMOCK_UNVERSIONED_WIKIS = [\n 'DesignDoc.wiki',\n 'DevGuide.wiki',\n 'KnownIssues.wiki'\n ]\n\n\ndef DropWikiSuffix(wiki_filename):\n \"\"\"Removes the .wiki suffix (if any) from the given filename.\"\"\"\n\n return (wiki_filename[:-len('.wiki')] if wiki_filename.endswith('.wiki')\n else wiki_filename)\n\n\nclass WikiBrancher(object):\n \"\"\"Branches ...\"\"\"\n\n def __init__(self, dot_version):\n self.project, svn_root_path = common.GetSvnInfo()\n if self.project not in ('googletest', 'googlemock'):\n sys.exit('This script must be run in a gtest or gmock SVN workspace.')\n self.wiki_dir = svn_root_path + '/wiki'\n # Turn '2.6' to 'V2_6_'.\n self.version_prefix = 'V' + dot_version.replace('.', '_') + '_'\n self.files_to_branch = self.GetFilesToBranch()\n page_names = [DropWikiSuffix(f) for f in self.files_to_branch]\n # A link to Foo.wiki is in one of the following forms:\n # [Foo words]\n # [Foo#Anchor words]\n # [http://code.google.com/.../wiki/Foo words]\n # [http://code.google.com/.../wiki/Foo#Anchor words]\n # We want to replace 'Foo' with 'V2_6_Foo' in the above cases.\n self.search_for_re = re.compile(\n # This regex matches either\n # [Foo\n # or\n # /wiki/Foo\n # followed by a space or a #, where Foo is the name of an\n # unversioned wiki page.\n r'(\\[|/wiki/)(%s)([ #])' % '|'.join(page_names))\n self.replace_with = r'\\1%s\\2\\3' % (self.version_prefix,)\n\n def GetFilesToBranch(self):\n \"\"\"Returns a list of .wiki file names that need to be branched.\"\"\"\n\n unversioned_wikis = (GTEST_UNVERSIONED_WIKIS if self.project == 'googletest'\n else GMOCK_UNVERSIONED_WIKIS)\n return [f for f in os.listdir(self.wiki_dir)\n if (f.endswith('.wiki') and\n not re.match(r'^V\\d', f) and # Excluded versioned .wiki files.\n f not in unversioned_wikis)]\n\n def BranchFiles(self):\n \"\"\"Branches the .wiki files needed to be branched.\"\"\"\n\n print 'Branching %d .wiki files:' % (len(self.files_to_branch),)\n os.chdir(self.wiki_dir)\n for f in self.files_to_branch:\n command = 'svn cp %s %s%s' % (f, self.version_prefix, f)\n print command\n os.system(command)\n\n def UpdateLinksInBranchedFiles(self):\n\n for f in self.files_to_branch:\n source_file = os.path.join(self.wiki_dir, f)\n versioned_file = os.path.join(self.wiki_dir, self.version_prefix + f)\n print 'Updating links in %s.' % (versioned_file,)\n text = file(source_file, 'r').read()\n new_text = self.search_for_re.sub(self.replace_with, text)\n file(versioned_file, 'w').write(new_text)\n\n\ndef main():\n if len(sys.argv) != 2:\n sys.exit(__doc__)\n\n brancher = WikiBrancher(sys.argv[1])\n brancher.BranchFiles()\n brancher.UpdateLinksInBranchedFiles()\n\n\nif __name__ == '__main__':\n main()\n" }, { "path": "test/googletest/scripts/run_with_path.py", "content": "#!/usr/bin/env python\n#\n# Copyright 2010 Google Inc.
