wp-plugin-testing

Use when writing or setting up tests for a WordPress plugin — PHPUnit integration tests using WP_UnitTestCase with the WP test suite (bin/install-wp-tests.sh, phpunit.xml.dist, tests/bootstrap.php), unit tests with Brain Monkey (when() / expect() / Mockery) or WP_Mock, test factories (factory()->post->create(), ->user->create(), ->term->create()), HTTP request mocking with add_filter pre_http_request, AJAX testing with WP_Ajax_UnitTestCase, redirect/exit testing via exception-throwing pattern, multisite tests (WP_MULTISITE=1), acceptance tests with Codeception + wp-browser, or GitHub Actions CI matrix for PHP x WP versions. Triggers: "write a test for this", "unit test this function", "set up PHPUnit for my plugin", "mock this WP function", "Brain Monkey setup", "WP_Mock", "test is failing", "how do I test a hook", "test my REST endpoint", "factory()->post->create()", "install the WP test suite", "test my wp_mail call", "integration test setup", "bin/install-wp-tests.sh", "phpunit.xml.dist", "WP_UnitTestCase", "WP_Ajax_UnitTestCase", "pre_http_request mock", "test a redirect", "WP_MULTISITE=1 test", "Codeception wp-browser", "Brain Monkey setUp tearDown", "PHP x WP version matrix in CI", "test a wp_schedule_event", "assert hook was called". Not for: E2E browser tests — use `wp-admin-browser` for those.
