Run PHPUnit tests in Github Actions.

PHPUnit is a programmer-oriented testing framework for PHP.

It is an instance of the xUnit architecture for unit testing frameworks.

Usage

Create your Github Workflow configuration in .github/workflows/ci.yml or similar.

name: CI

on: [push]

jobs:
  build-test:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v3
    - uses: php-actions/composer@v6 # or alternative dependency management
    - uses: php-actions/phpunit@v3
    # ... then your own project steps ...

Version numbers

This action is released with semantic version numbers, but also tagged so the latest major release's tag always points to the latest release within the matching major version.

Please feel free to use uses: php-actions/phpunit@v3 to always run the latest version of v3, or uses: php-actions/phpunit@v3.0.0 to specify the exact release.

Example

We've put together an extremely simple example application that uses php-actions/phpunit. Check it out here: https://github.com/php-actions/example-phpunit.

Inputs

The following configuration options are available:

• version The version of PHPUnit to use e.g. latest, 9 or 9.5.0 (default: composer - use the version specified in composer.json)
• php_version The version of PHP to use e.g. 7.4 (default: latest)
• php_extensions Space-separated list of extensions using php-build e.g. xdebug mbstring (default: N/A)
• vendored_phpunit_path The path to a phar file already present on the runner (default: N/A)
• configuration Path to the phpunit.xml file (default: test/phpunit/phpunit.xml)
• log_junit Log test execution in JUnit XML format to file
• log_teamcity Log test execution in TeamCity format to file
• testdox_html Write documentation in HTML format to file
• testdox_text Write documentation in Text format to file
• memory_limit The memory limit to run your tests with (default: 128M)
• bootstrap The path to the bootstrap file
• filter Filter which tests to run
• testsuite Specify a testsuite to run
• group Only runs tests from the specified group(s)
• exclude_group Exclude tests from the specified group(s)
• test_suffix Only search for test in files with specified suffix(es)
• whitelist Path to directory to whitelist for code coverage analysis (phpunit <= 8)
• coverage_filter Include directory in code coverage reporting (phpunit >= 9)
• coverage_clover Generate code coverage report in Clover XML format
• coverage_cobertura Generate code coverage report in Cobertura XML format required
• coverage_crap4j Generate code coverage report in Crap4J XML format
• coverage_html Generate code coverage report in HTML format
• coverage_php Export PHP_CodeCoverage object to file
• coverage_text Generate code coverage report in text format (true to output to console, path to output to file)
• coverage_xml Generate code coverage report in PHPUnit XML format
• args Extra arguments to pass to the phpunit binary

The syntax for passing in a custom input is the following:

...

jobs:
  unit-tests:

    ...

    - name: PHPUnit tests
      uses: php-actions/phpunit@v3
      with:
        configuration: "custom/path/to/phpunit.xml"
        memory_limit: "256M"

If you require other configurations of phpunit, please request them in the Github issue tracker

PHP and PHPUnit versions

It's possible to run any version of PHPUnit under any version of PHP, with any PHP extensions you require. This is configured with the following inputs:

• version - the version number of PHPUnit to run e.g. latest, 9 or 9.5.0 (default: composer). Using the default value, composer will install the version specified in composer.json
• php_version - the version number of PHP to use e.g. 7.4 (default: latest)
• php_extensions - a space-separated list of extensions to install using php-build e.g. xdebug mbstring (default: N/A)

Please note the version number specified within your Action configuration must match your composer.json major version number. For example, if your composer.json requires phpunit/phpunit 8.5.8, you must use the version: 8.5.8 input, as major versions of PHPUnit are incompatible with each other.

If you require a specific version that is not compatible with Github Actions for some reason, please make a request in the Github issue tracker.

Coverage

To store the code coverage, use the coverage_* input that is appropriate for your needs. Coverage information is made possible by using the xdebug extension, which will be required to be added to the php_extensions input to work.

Example:

jobs:
  unit-tests:

    ...

    - name: PHPUnit tests
      uses: php-actions/phpunit@v3
      with:
        php_extensions: "xdebug"
        coverage_clover: "coverage/clover.xml"

The above example will output coverage information to the terminal. Pass a file path to output to a file.

If you want to report coverage information somewhere, please see the code-coverage action.

Github Actions releases

Previously, the Github Actions release version numbers were in sync with the PHPUnit version, but this imposed too many limitations. For the next 12 months (until 30th November 2021), v7, v8 and v9 branches will still point to their existing commits, but we have reverted to v1-based Actions releases, allowing PHPUnit version number to be specified from your configuration, using the version input variable.
