Use an isolated Joomla test installation with PHP 8.3+, a supported database, Cassiopeia as the site template, Atum for administration and this module installed. These tests create development data and are not intended for production sites.
From the Joomla root, first run php /path/to/tests/seed.php. This creates three public fixture articles and seven published module layouts idempotently. seed.php currently uses MySQL/MariaDB PDO and the site's configuration without printing credentials.
Run php /path/to/tests/integration.php from the Joomla root (or set JOOMLA_ROOT). Its 34 assertions cover image modes, compact/pretty/escaped JSON, malformed/empty image data, alt-text fallback, result counts, ordering, featured schedules and missing-carousel fallback. Temporary changes use the injected Joomla database connection and are rolled back on success or failure. Assertion failures exit nonzero. Run this only on the isolated fixture site.
For browser checks, Python Playwright and Chromium are required. Export JOOMLA_TEST_ADMIN_PASSWORD securely and optionally JOOMLA_TEST_ADMIN_USERNAME (default reviewadmin). Never commit these values. JOOMLA_TEST_MATRIX is an optional JSON list of [version, local_port] pairs; defaults are 6.1.1:8111, 6.1.4:8114 and 6.2.0:8120. The admin account must have permission to manage site modules.
Run python3 tests/browser-smoke.py. It verifies all seven layouts, actual carousel advancement, asset delivery, seven JSON-LD ItemLists, an Atum module edit form and no JavaScript errors. Set JOOMLA_TEST_RESULT_FILE to save JSON results outside the source tree if needed.
The release was tested on Joomla 6.1.1, 6.1.4 and 6.2.0 with PHP 8.3.32 and MariaDB 11.4. PostgreSQL execution and third-party templates have not been tested.
