WordPress Plugin Testing with Docker and PHPUnit
Setting up PHPUnit for WordPress plugins is a multi-step friction fest: install WordPress, Composer, the test suite, SVN, MySQL, debug environment issues. Then your CI fails anyway because the environment doesn’t match your laptop. This Docker image solves both problems. One image, PHP 7.4–8.4 support, same environment everywhere. Local tests run exactly like CI tests. No setup steps. No environment drift.
