Getting coverage working with CodeClimate in CI

ci.yml

# make CCTR an alias for './cc-test-reporter'
# NOTE: the other gist [https://gist.github.com/armandofox/29d09a904c08c26f5e50cea60219f2fc]
#  showing env.rb relies on checking $CCTR to see if it is set,
#   as a way to know whether we are running in CI or locally.
    runs-on: ubuntu-latest
    env:
      CCTR: ./cc-test-reporter
      BUNDLE_WITHOUT: production
      TZ: America/Los_Angeles

# somewhere you need a step that actually fetches the cctr binary, 
# and tells it you're going to do a build:
    - name: Setup CodeClimate test-reporter
      run: |
        curl -L https://codeclimate.com/downloads/test-reporter/test-reporter-latest-linux-amd64 > $CCTR
        chmod +x $CCTR
        $CCTR before-build

# presumably you already have a step that installs gems, etc.  when you're ready to run tests:

    - name: run RSpec tests and capture coverage
      run: |
        bundle exec rspec
        $CCTR format-coverage --output coverage/codeclimate.$SUITE.json --input-type simplecov
        
# if you use a headless browser for any Cucumber scenarios, don't waste time installing it until
#   after rspec has passed.  I use ChromeForTesting, which also requires the corresponding version
#   of Chromedriver.  Make sure you've specified in features/support/env.rb whichever headless
#   browser you are installing here.
    - name: Install Chrome For Testing and Chromedriver
      uses: browser-actions/setup-chrome@v1
      id:  install-chromedriver
      with:
        chrome-version: stable
        install-chromedriver: true
        install-dependencies: true

# see the separate gist 
    - name: run Cucumber tests using config/cucumber.yml options, and capture coverage
      env:
        CHROMEDRIVER_PATH: ${{ steps.install-chromedriver.outputs.chromedriver-path }} 
        CHROME_FOR_TESTING_PATH: ${{ steps.install-chromedriver.outputs.chrome-path }} 
      run: |
        bundle exec cucumber --profile ci-report
        $CCTR format-coverage --output coverage/codeclimate.$SUITE.json --input-type simplecov
