Quail was born during a time when accessibility\ntesting, as a discipline, was maturing. There were numerous teams building solutions\nin parallel -- Quail was just one of these. In the end, we were all orbiting around\nthe same general approach. Technology may have been a distinguishing factor a couple\nyears ago, but even these advantages have largely dissolved as solutions have evolved\nand improved over time.\n\nGiven the realities of the market and the limited time that the Quail team can\ndevote to this project, we are initializing deprecation for this project. Folks\nare welcome to fork it or volunteer to maintain it, but realistically, there are\nbetter options out there.\n\nIf you are looking for one, we recommend [aXe: the Accessibility Engine](https://github.com/dequelabs/axe-core) by [Deque Labs](https://github.com/dequelabs).\n\n# Quail: Accessibility Information Library\n\n**The project website is [quailjs.io](http://quailjs.io/).**\n\nQuail is a Node module and a jQuery plugin that lets you easily check HTML for adherence to accessibility standards. It comes with over 200 tests which implement Open Accessibility Tests and comes with WCAG 1.0, WCAG 2.0, and Section 508 guidelines.\n\nDevelopers can build their own guidelines, or easily build a custom guideline that integrates with their project. While the project supports checking entire HTML pages, integration with a CMS to check partial HTML content is probably the most popular use case.\n\n**Notice for developers working in the 2.2.x version.**\n\nPlease base your changes on the [```master-2.2.x```](https://github.com/quailjs/quail/tree/master-2.2.x) branch.\n\n## Requirements\n\nYou will need the following installed on your system to run Quail.\n\n1. [Node.js](https://nodejs.org/download/)\n1. [Grunt & Grunt CLI](http://gruntjs.com/installing-grunt)\n1. [Bower](http://bower.io/)\n1. [Java JDK](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) (To run Selenium Server)\n1. [Karma](http://karma-runner.github.io/0.8/intro/installation.html)\n\n## Using Quail\n\n### Setup\n\nRun the following commands to build Quail.\n\n```bash\ngit clone https://github.com/quailjs/quail.git\ncd quail\nnpm install\nbower install\ngrunt build\n```\n\n### Using Quail from the command line\n\nTo see the Quail CLI API, run the following. You can also add the Quail bin directory to your PATH if you are so inclined.\n\n```bash\n./bin/quail --help\n```\n\nOnce the command is set up, you can run the following to test any addressable web page.\n\n```bash\n./bin/quail eval http://placekitten.com\n```\n\nWrite the results as a JSON object out to file in an existing directory.\n\n```bash\n./bin/quail evaluate http://placekitten.com -o ./analyses\n```\n\nYou can also pass configurations to the evaluator.\n\n```bash\n./bin/quail evaluate http://placekitten.com -c ~/path/to/myconfig.json -o ./analyses\n```\n\nThis is the default set of configurations. Your configurations will replace the defaults.\n\n```json\n{\n \"phantomjs\": {\n \"resourceTimeout\": 5000\n },\n \"blacklists\": {\n \"domains\": [\n \"fbstatic.com\",\n \"facebook.com\",\n \"twitter.com\",\n \"google-analytics.com\",\n \"googleadservices.com\",\n \"googlesyndication.com\",\n \"perfectaudience.com\",\n \"typekit.com\",\n \"sharethis.com\",\n \"doubleclick.com\",\n \"optimizely.com\",\n \"gigya.com\"\n ],\n \"mimetypes\": [\n \"application/x-shockwave-flash\",\n \"application/(ms)?(word|powerpoint|excel)\"\n ],\n \"headers\": []\n }\n}\n```\n\nThe ```phantomjs``` configurations affect the PhantomJS runtime.\n\nThe ```blacklists``` block resource resource requests from PhantomJS by the resource's domain, its mime type or a header name in the request. Currently the only header value that can be blocked is the value of Accept (mime type).\n\nTo work on an existing assessment in a browser (so that breakpoints can be set in the console), run the following.\n\n```bash\n./bin/quail dev aMustHaveTitle\n```\n\nThe following is experimental, which means it probably won\\'t work. You can generate a new assessment with this command.\n\n```bash\n./bin/quail gen someNewAssessment\n```\n\n## Testing\n\n### Core unit tests in Karma\n\n```bash\n./node_modules/karma/bin/karma start ./config/karma-unit.conf.js\n```\n\n### Testing assessments in Selenium\n\nAll assessments. This takes about 10 minutes to run.\n\n```bash\nnode ./test/assessmentSpecs/testRunner.js\n```\n\nAn individual assessment. This takes about 2 seconds to run.\n\n```bash\nnode ./test/assessmentSpecs/testRunner.js -I aMustHaveTitle\n```\n\nIn a specific browser.\n\n```bash\n_BROWSER=chrome node ./test/assessmentSpecs/testRunner.js\n```\n\n## Documentation\n\n[Full documentation is available via readthedocs.org](https://quail.readthedocs.org/en/latest/).\n\n## Contributing\n\nPull requests should be made against the **master** branch.\n\nWe are currently looking for the following types of contritions.\n\n1. Help with our current [Milestone objectives](https://github.com/quailjs/quail/milestones/Refactoring%20to%20a%20Selenium-based%20test%20runner%20and%20Mocha/Chai%20assessment%20tests).\n1. JavaScript enthusiasts who want a chance to build out:\n 1. A dependency injection load pattern: [Replace our load-order-depending spinup with an Inversion of Control pattern](https://github.com/quailjs/quail/issues/297)\n 1. A pub/sub pattern: [Refactor the custom event bubbling code in the core Classes (e.g. TestCollection) to use a real event pub/sub library](https://github.com/quailjs/quail/issues/351)\n 1.
