# go-test-trace
[](https://circleci.com/gh/rakyll/go-test-trace/tree/main)
go-test-trace is like go test but it also generates
distributed traces.
Generated traces are exported in OTLP to a
[OpenTelemetry collector](https://github.com/open-telemetry/opentelemetry-collector).
You need to run go-test-trace alongside a collector to export data to
distributed tracing service.
## Installation
```
go get -u github.com/rakyll/go-test-trace
```
## Usage
You can use go-test-trace as a drop-in replacement for go test.
The following example will generate a distributed trace
and export it to a collector available at "127.0.0.1:55680".
```
$ go-test-trace ./example
=== RUN TestStart
--- PASS: TestStart (0.50s)
=== RUN TestStartWithOptions
--- PASS: TestStartWithOptions (1.00s)
=== RUN TestFileParser
--- FAIL: TestFileParser (0.30s)
=== RUN TestLoading
=== PAUSE TestLoading
=== RUN TestLoading_abort
=== PAUSE TestLoading_abort
=== RUN TestLoading_interrupt
=== PAUSE TestLoading_interrupt
=== CONT TestLoading
=== CONT TestLoading_abort
=== CONT TestLoading_interrupt
--- PASS: TestLoading_interrupt (0.08s)
--- PASS: TestLoading (1.00s)
--- PASS: TestLoading_abort (2.50s)
FAIL
FAIL github.com/rakyll/go-test-trace/example 4.823s
exit status 1
make: *** [default] Error 1
```
Alternatively, you can use -stdin option to parse
the output of go test. This option won't be as accurate
in terms of timestamps because it will generate trace spans
as it sees output in stdin.
```
$ go test -v ./example | go-test-trace -stdin
```
You can export to any collector by using the endpoint flag:
```
$ go-test-trace -endpoint=my-otel-collector.io:9090 ./example
```
You can make the go-test-trace to participate into an existing
trace with the traceparent flag.
```
$ go-test-trace -traceparent=00-0af7651916cd43dd8448eb211c80319c-b7ad6b7169203331-01 ./example
```
## Running the collector
An example collector configuration is available at example/collector.yaml.
It exports to Honeycomb but you can choose to any other destination by
changing the configuration. Please edit the write key and data set
with your details from Honeycomb before using it.
Then, you can run the collector locally by the following command
and export the traces to Honeycomb:
```
$ docker run --rm -p 4317:4317 -p 55680:55680 -p 8888:8888 \
-v "${PWD}/example/collector.yaml":/collector.yaml \
--name awscollector public.ecr.aws/aws-observability/aws-otel-collector:latest \
--config collector.yaml;
```
You can use any configuration supported by [ADOT](https://github.com/aws-observability/aws-otel-collector)
or export to any other OpenTelemetry collector.
