Run PHPUnit Coverage Check as a github action.

This action makes use of code from psalm/psalm-github-actions. Without them, I admittedly would have been lost. Much of the code being used from them are for the Dockerfile, action.yml, entrypoint.sh, and .github/workflows/watch.yml files.

Each release will indicate which version of PHPUnit Coverage Check is being used.

You can use the Docker image directly:

name: PHPUnit Coverage Check

on: [push, pull_request]

jobs:
  phpunit-coverage-check:
    name: PHPUnit Coverage Check
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      # ... your steps to run PHPUnit and generate a clover file ...

      - name: Coverage Check
        uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action
        with:
          clover_file: 'build/logs/clover.xml'
          threshold: 100

Or, the GitHub marketplace action:

       - name: Coverage Check
-        uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action
+        uses: ericsizemore/[email protected]

You can also specify a specific PHPUnit Coverage Check version. Currently supports PHPUnit Coverage Check 2.0.0 and greater.

       - name: Coverage Check
-        uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action
+        uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action:2.0.0

There are four main possible inputs, beyond customizing Composer and ssh authentication.

The clover.xml file to be parsed. It must be a valid, PHPUnit generated, clover report.

The threshold that determines the acceptable amount of coverage. Must be at least 1 and no more than 100.

Whether only the percentage of coverage is returned. Accepts boolean values (true or false).

Whether to process and display coverage for all files found within the clover report. Accepts boolean values (true or false)

Below is an example workflow that uses PHPUnit to run unit tests and generate the clover report, and ties in this action to parse it.

name: PHPUnit Coverage Check

on: [push, pull_request]

jobs:
  phpunit-coverage-check:
    name: PHPUnit Coverage Check
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Install PHP ${{ matrix.php }}
        uses: shivammathur/setup-php@master
        with:
           php-version: ${{ matrix.php }}
           extensions: mbstring, 
           coverage: xdebug, pcov
           tools: composer:v2

      - name: Install dependencies
        run: composer install --prefer-dist --no-progress

      - name: Run test suite
        run: ./vendor/bin/phpunit --coverage-clover clover.xml

      - name: Coverage Check
        uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action
        with:
          clover_file: 'clover.xml'
          threshold: 100

Specify composer_require_dev: true to install dev dependencies and composer_ignore_platform_reqs: true in order to ignore platform requirements.

These are both set to false by default.

       - name: Coverage Check
         uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action
+        with:
+          composer_require_dev: true
+          composer_ignore_platform_reqs: true

If your composer file is not in the directory, you can specify the relative directory.

Use the following config:

       - name: Coverage Check
         uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action
+        with:
+          relative_dir: ./subdir

If you have private composer dependencies, SSH authentication must be used. Generate an SSH key pair for this purpose and add it to your private repository's configuration, preferably with only read-only privileges. On Github, for instance, this can be done by using deploy keys.

Add the key pair to your project using Github Secrets, and pass them into this action by using the ssh_key and ssh_key_pub inputs. If your private repository is stored on a server other than github.com, you also need to pass the domain via ssh_domain.

Example:

jobs:
  build:

    ...

    - name: Coverage Check
      uses: docker://ghcr.io/ericsizemore/phpunit-coverage-check-action
      with:
        ssh_key: ${{ secrets.SOME_PRIVATE_KEY }}
        ssh_key_pub: ${{ secrets.SOME_PUBLIC_KEY }}
        # Optional:
        ssh_domain: my-own-github.com 

github.com, gitlab.com and bitbucket.org are automatically added to the list of SSH known hosts. You can provide your own domain via ssh_domain input.
