Instance Method Details

#detect_runner(ci_log) ⇒ Runners::MinitestRunner, Runners::RSpec

Try to guess which runner (Minitest, RSpec) was responsible for this log output.

The runner is the most important part of CI Runner. It’s what determine the failures for a CI log, as well as how to rerun those only.

Raises:

  • (Error) —

    In case none of the runners could detect the log output.

  runner = [Runners::MinitestRunner, Runners::RSpec].find(raise_if_not_found) do |runner|
    runner.match?(ci_log)
  end

  runner.new(ci_log)

#fetch_ci_checks(repository, commit, &block) ⇒ Array<Check::Base>

Makes a request to GitHub to retrieve the checks for a commit. Display a nice UI with a spinner while the user wait.

  ci_checks
end

#find(ci_checks, run_name) ⇒ Check::Base

Find the CI check the user requested from the list of upstream checks. This method is useful only when the user passes the ‘–run-name` flag to `ci-runner`. This makes sure the CI check actually exists.

Raises:

  • (Error) —

    If no CI checks with the given run_name could be found.

  • (Error) —

    If the CI check was successfull. No point to continue as there should be no tests to rerun.

#github_ci(repository, commit) ⇒ Array<Check::Github>

Download the GitHub checks. This is used in case a project uses GitHub itself as its CI provider.

    Check::Github.new(repository, commit, *check_run.values_at("name", "conclusion", "id"))
  end
end

#other_ci(repository, commit) ⇒ Array<Check::CircleCI, Check::Unsupported>

Download the Commit Statuses for this commit. Some CI provider (like GitHub or Buildkite), doesn’t use the GitHub Check API, but instead this API.
