Worked on stabilizing test automation for the modell-aachen/modac-dev-machine-setup repository following a major reorganization of the codebase. Focused on aligning the QTest shell script with the new folder structure, ensuring that the backend test executable was correctly referenced within the core directory. This adjustment improved the reliability of continuous integration pipelines by preventing path-related test failures and reduced maintenance overhead for the dev-machine-setup tooling. Leveraged shell scripting skills to validate and update path resolution logic, supporting smoother downstream QA and integration processes. No new features were released, as the primary emphasis was on maintainability and robust test execution.
