JUnit Annotate Buildkite Plugin

A Buildkite plugin that parses junit.xml artifacts (generated across any number of parallel steps) and creates a build annotation listing the individual tests that failed.

Example

The following pipeline will run test.sh jobs in parallel, and then process all the resulting JUnit XML files to create a summary build annotation.

steps:
  - command: test.sh
    parallelism: 50
    artifact_paths: tmp/junit-*.xml
  - wait: ~
    continue_on_failure: true
  - plugins:
      - junit-annotate#v1.7.0:
          artifacts: tmp/junit-*.xml

Configuration

artifacts (required)

The artifact glob path to find the JUnit XML files.

Example: tmp/junit-*.xml

job-uuid-file-pattern (optional)

Default: -(.*).xml

The regular expression (with capture group) that matches the job UUID in the junit file names. This is used to create the job links in the annotation.

To use this, configure your test reporter to embed the $BUILDKITE_JOB_ID environment variable into your junit file names. For example "junit-buildkite-job-$BUILDKITE_JOB_ID.xml".

failure-format (optional)

Default: classname

This setting controls the format of your failed test in the main annotation summary.

There are two options for this:

  • classname
    • displays: MyClass::UnderTest text of the failed expectation in path.to.my_class.under_test
  • file
    • displays: MyClass::UnderTest text of the failed expectation in path/to/my_class/under_test.file_ext

fail-build-on-error (optional)

Default: false

If this setting is true and any errors are found in the JUnit XML files during parsing, the annotation step will exit with a non-zero value, which should cause the build to fail.

Developing

To test the plugin hooks (in Bash) and the junit parser (in Ruby):

docker-compose run --rm plugin &&
docker-compose run --rm ruby

To test the Ruby parser locally:

cd ruby
rake

To test your plugin in your builds prior to opening a pull request, you can refer to your fork and SHA from a branch in your pipeline.yml.
