LakeDrops' Guide to Automated Weekly Testing for Drupal Modules Using GitLab CI

Jurgen Haas, writing for LakeDrops, has published a detailed guide on using GitLab CI Templates to automate weekly testing for Drupal modules, emphasizing the need for proactive detection of compatibility issues with current and future versions of Drupal core. The article outlines how to configure a `.gitlab-ci.yml` file to include community-maintained templates that support testing across multiple Drupal versions and test types, such as linting, static analysis, and unit tests. 

It highlights the importance of stricter configurations, including disallowing failures for tools like PHPStan and PHPCS, and raising analysis levels to ensure meaningful results. Haas explains how to schedule weekly pipelines using GitLab’s UI and extend the same testing practices to private custom modules through self-hosted GitLab instances, using the same templates and setting up dedicated runners. The guide concludes by underscoring the benefits of a unified testing strategy for both public and private modules and references a companion article on full-site dependency testing for broader quality assurance.
