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.
