This GitHub Action uploads coverage reports to Codacy on all commits and pull requests, letting you track code coverage on the Codacy UI. After setting it up, you can optionally enable status checks on pull requests to avoid adding untested code or decreasing coverage.

Codacy is an automated code review tool that makes it easy to ensure your team is writing high-quality code by analyzing more than 40 programming languages such as PHP, JavaScript, Python, Java, and Ruby. Codacy allows you to define your own quality rules, code patterns and quality settings you'd like to enforce to prevent issues on your codebase.

Why do you need to measure code coverage?

Before setting up Codacy Coverage Reporter GitHub Action you must have tests and use tools to generate coverage reports for the source code files in your repository.

To upload coverage to Codacy using the GitHub Action using default settings:

1. Set up an API token to allow the GitHub Action to authenticate on Codacy:

   • If you're setting up one repository, obtain a project API token and store it as an encrypted secret for your repository with the name CODACY_PROJECT_TOKEN.
   • If you're setting up multiple repositories, obtain an account API token and store it as an encrypted secret for your organization with the name CODACY_API_TOKEN.

   ⚠️ Never write API tokens to your configuration files and keep your API tokens well protected, as they grant owner permissions to your projects on Codacy.

2. Generate a supported code coverage report on each push to your repository.

3. Add the following to a file .github/workflows/codacy-coverage-reporter.yaml in your repository, where PATH_TO_REPORT is the path to the coverage report:

   name: Codacy Coverage Reporter
   
   on: ["push"]
   
   jobs:
     codacy-coverage-reporter:
       runs-on: ubuntu-latest
       name: codacy-coverage-reporter
       steps:
         - uses: actions/checkout@v2
         - name: Run codacy-coverage-reporter
           uses: codacy/codacy-coverage-reporter-action@v1
           with:
             project-token: ${{ secrets.CODACY_PROJECT_TOKEN }}
             # or
             # api-token: ${{ secrets.CODACY_API_TOKEN }}
             coverage-reports: <PATH_TO_REPORT>
             # or a comma-separated list for multiple reports
             # coverage-reports: <PATH_TO_REPORT>, <PATH_TO_REPORT>

4. Optionally, to add coverage results to GitHub status checks, configure a quality gate for coverage and enable sending status checks on Codacy.

The Codacy GitHub Action is a wrapper for running the Codacy Coverage Reporter CLI and supports the following subset of parameters available for the command report:
