CircleCI::CoverageReporter

CircleCI::CoverageReporter reports test coverage to your GitHub repository.

Example

Getting started

1. Add CircleCI::CoverageReporter to your Gemfile and bundle install:

   gem 'circleci-coverage_reporter', group: :test
   

2. Load circleci/coverage_reporter/rake_task in your Rakefile:

   require 'circleci/coverage_reporter/rake_task' if ENV['CIRCLECI']
   

3. Issue CircleCI and GitHub tokens and add them to build environment variables as follows:

   Name	Value
   COVERAGE_REPORTER_CIRCLECI_TOKEN	CircleCI API token with "view-builds" scope
   COVERAGE_REPORTER_VCS_TOKEN	GitHub personal access token with "repo" or "public_repo" scope

4. Add the following step to your circle.yml:

   test:
     post:
     - bundle exec rake circleci:report_coverage
   

Run manually

You must configure circleci_token and vcr_token before CircleCI::CoverageReporter.run:

CircleCI::CoverageReporter.configure do |config|
  config.circleci_token = YOUR_CIRCLECI_API_TOKEN
  config.vcr_token = YOUR_GITHUB_PERSONAL_ACCESS_TOKEN
end

CircleCI::CoverageReporter.run

Reporters

SimpleCov

CircleCI::CoverageReporter::SimpleCov::Reporter handles coverage files generated by SimpleCov.

It expects that coverage files are located in $CIRCLE_ARTIFACTS/coverage directory:

# spec/spec_helper.rb
require 'simplecov'
# Save to CircleCI's artifacts directory if we're on CircleCI
SimpleCov.coverage_dir(File.join(ENV['CIRCLE_ARTIFACTS'], 'coverage')) if ENV['CIRCLECI']
SimpleCov.start

If you put files in another directory, say $CIRCLE_ARTIFACTS/foo/bar, you have to set reporter as follows:

CircleCI::CoverageReporter.configure do |config|
  config.reporters << CircleCI::CoverageReporter::SimpleCov::Reporter.new('foo/bar')
end

Flow

CircleCI::CoverageReporter::Flow::Reporter handles coverage files generated by flow-coverage-report

It expects that there is $CIRCLE_ARTIFACTS/flow-coverage/flow-coverage.json:

$(npm bin)/flow-coverage-report -t json -o $CIRCLE_ARTIFACTS/flow-coverage

If you put the file in another path, say $CIRCLE_ARTIFACTS/foo/bar/flow-coverage.json, you have to set reporter as follows:

CircleCI::CoverageReporter.configure do |config|
  config.reporters << CircleCI::CoverageReporter::Flow::Reporter.new('foo/bar')
end
