Blinka reporter

What does this gem do?

Generate a test results report for Minitest or interpret a junit-report from Rspec. These results can then be reported to Blinka which posts your test results directly in your Github Pull Requests.

How do I install the gem?

Run

gem install blinka-reporter

or add to your Gemfile

gem 'blinka-reporter', '~> 0.7.2'

Which ruby testing frameworks are supported?

  • Minitest
  • Rspec

Please reach out for other frameworks or create a reporter yourself.

What is Blinka?

Blinka is a web service developed by @davidwessman to store test results from CI and report interesting results back to Github, right in the pull request.

How to generate test report in the right format?

Minitest

BLINKA_PATH=./tests.json bundle exec rails test

Output as ./tests.json.

Rspec

Make sure rspec_junit_formatter is installed.

bundle exec rspec --formatter RspecJunitFormatter --out ./rspec.xml

How can I send report in Github Action?

Add a step to your Github Action Workflow after running tests:

- name: Minitest
  env:
    BLINKA_PATH: ./results.json
  run: bundle exec rake test

// Add a tag to be able to separate multiple jobs, e.g. "ruby-${{ matrix.ruby }}".
// This is optional.
- name: Export Blinka-metadata
  if: always()
  run: |
    echo "ruby gem" > ./blinka_tag

// Archive all files required by Blinka, json, the tag and any images.
// Blinka will automatically fetch the results when the Github Action Workflow is finished.
- name: Archive results for Blinka
  if: always()
  uses: actions/upload-artifact@v3
  with:
    name: blinka-${{ strategy.job-index }}
    path: |
      ./results.json
      ./blinka_tag
- name: Rspec
  run: bundle exec rspec --formatter RspecJunitFormatter --out ./rspec.xml

- name: Export Blinka-metadata
  if: always()
  run: |
    echo "ruby gem" > ./blinka_tag

- name: Archive results for Blinka
  if: always()
  uses: actions/upload-artifact@v3
  with:
    name: blinka-${{ strategy.job-index }}
    path: |
      ./rspec.xml
      ./blinka_tag

How to make multiple test runs into one report?

For example when running tests in parallel you might need to run system tests separately. Output the test results to different paths with BLINKA_PATH.

- name: System tests
  env:
    BLINKA_PATH: ./system_tests.json
    PARALLEL_WORKERS: 1
  run: bundle exec rails test:system

- name: Tests
  env:
    BLINKA_PATH: ./tests.json
  run: bundle exec rails test

- name: Archive results for Blinka
  if: always()
  uses: actions/upload-artifact@v3
  with:
    name: blinka-${{ strategy.job-index }}
    path: |
      ./tests.json
      ./system_tests.json
      ./blinka_tag

How can I run multiple test runs to one file?

For Minitest this can be done by setting BLINKA_APPEND=true, make sure to clean the BLINKA_PATH file before running the tests.

- name: Tests 1
  env:
    BLINKA_PATH: ./tests.json
    BLINKA_APPEND: true
  run: bundle exec rails test:system

- name: Tests 2
  env:
    BLINKA_PATH: ./tests.json
    BLINKA_APPEND: true
  run: bundle exec rails test

How can I report tests in TAP-format?

TAP-format (Test anything protocol) is used to parse tests results on for example Heroku CI.

Generate your test results like above, replace <path> with your json or xml file.

bundle exec blinka_reporter --tap --path <path>

Development

Release new version

  1. Update version in CHANGELOG.md and include changes.
  2. Update version in lib/blinka_reporter/version.rb.
  3. Create pull request and merge to default branch.
  4. gem build blinka_reporter.gemspec (make sure it matches the bumped version).
  5. gem push blinka-reporter-{version}.gem (had to use --otp because I could not enter it when prompted).
  6. Create a release and tag on Github for history.
