Worked on stabilizing automated test workflows in the ILIAS-eLearning/ILIAS repository, focusing on backend development using PHP. Addressed a critical issue where test runs resulted in blank pages by correcting the command path and updating PHP files to reference the fully qualified namespace for the testScreen method. This involved modifying ilObjTestAccess.php and ilObjTestListGUI.php to ensure proper GUI class resolution, which improved the reliability of automated testing. The targeted bug fix reduced flaky failures during December 2024, enhancing the overall stability of the test suite. The work demonstrated attention to detail in backend logic and namespace management within PHP applications.
