Heroku Review Apps deployment status

A Github Action that tests the deployment status of a Heroku Review App.

Note: This Action is recommended for small projects. For medium to large projects, a different approach is recommended to save compute minutes. Check this Blog Post for detailed process of the approach.

Usage

• Include the action in the workflow

  name: Review App Test
  
  on:
      pull_request:
          branches:
          - master
  
  jobs:
    review-app-test:
  
      runs-on: ubuntu-latest
      
      steps:
      - name: Run review-app test
        id: review_app_test  # `id` value is used to refer the outputs from the corresponding action 
        uses: teamniteo/[email protected]
        env:
            GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          # Checks to be performed, default is all the checks
          checks: build, response
  
          # Delay for the application to be built in Heroku, default is 5 seconds
          build_time_delay: 5
  
          # Delay for the application to load and start serving, default is 5 seconds
          load_time_delay: 5
  
          # Interval for the repeating checks, default is 10 seconds
          interval: 10
  
          # Acceptable responses for the response check, default is 200
          accepted_responses: 200
  
          # Max time to be spent retrying for the build check, default is 120
          deployments_timeout: 120
  
          # Max time to be spent retrying for the response check, default is 120
          publish_timeout: 120
  
      # `steps.review_app_test.outputs.review_app_url` must be used in workflow to fetch the Review App URL 
      - name: Check review_app_url
        run: |
          echo "Outputs :"
          echo "- App name: ${{ steps.review_app_test.outputs.review_app_name }}"
          echo "- App url: ${{ steps.review_app_test.outputs.review_app_url }}"

Note: Work flow should include pull_request event.
