Docker PHP Test Suite
A docker app to run the PHP Test Suite.
Getting Started
For convenience, the PHP Test Suite can be run from an npm script.
npm run test:php
This runs the the phpunit container with docker-compose -f run --rm phpunit. On first use, the container will install the PHP Test Suite and perform the tests. Subsequent use will only perform the tests.
Re-install Test Suite
Re-installation is useful to update WordPress to the latest version. To do this, remove the existing test-suite volume using Docker. For example:
docker volume rm -f wc-admin-php-test-suite_test-suite
Then run the test suite normally using the npm script. Installation will be automatically performed.
Testing a single test case
PHPUnit flags can be passed to the npm script. To limit testing to a single test case, use the --filter flag.
npm run test:php -- --filter=<name of test>
Selecting the WordPress and WooCommerce Versions
By default, the minimum supported versions of WordPress and WooCommerce are used to build the test suite. This can be overridden with environment variables.
WP_VERSION=5.6 WC_VERSION=4.9.0 npm run test:php
Selecting PHP versions
The PHP test suite supports running tests in PHP 7 and 8. We do use a custom PHPUnit fork of version ~7.5 when running tests in PHP 8, for the reasoning why see this WooCommerce Readme.
As mentioned in the readme, when running tests in PHP 8 it will modify the composer files in /bin/composer/phpunit, please remember to not include these changes in any of your commits.
To run tests using PHP 8:
PHP_VERSION=8 npm run test:php
Development
When comitting changes to the Dockerfile or entrypoint.sh files, bump the wc-admin-php-test-suite-phpunit image tag version in docker-composer.xml. This will result in an image rebuild automatically upon next use, enabling the changes to be applied for all users.
