Worked on the richard67/joomla-cms repository to enhance test coverage and ensure compatibility with PHP 8.5. Focused on expanding the continuous integration pipeline by adding PHP 8.5 to both unit and integration test matrices, using YAML for configuration and PHP for test execution. This approach aimed to validate the codebase against the latest PHP version, reducing the risk of regressions during future upgrades. No major defects were addressed during this period, as the primary objective was to lay a foundation for smoother upgrade paths and more reliable releases by improving automated testing and integration workflows within the Joomla CMS project.
