Worked on the OpenLiberty/open-liberty repository to enhance the reliability of the command-line interface test suite, focusing on reducing flakiness and addressing locale-related failures. Improved the stability of tests around command-line argument parsing and help message validation by removing redundant assertions and refining verification logic to avoid Java warnings. These changes enabled faster feedback cycles and safer CLI modifications by increasing the consistency of continuous integration results. Utilized Java for test development, applying log analysis and testing skills to identify and resolve issues. The work contributed to more robust automated testing and streamlined the process for future command-line changes.
