Worked on enhancing the Lakekeeper repository by improving the robustness and reliability of its test suite. Focused on refining error handling within Python-based tests, specifically by replacing generic exception handling with precise PyIceberg exception classes. This targeted refactor ensured that tests accurately reflected expected error conditions, such as handling non-existent namespaces or tables, leading to clearer failure signals and more stable continuous integration outcomes. Leveraged skills in error handling, PyIceberg, and testing to address a key bug, resulting in a more maintainable and correct testing environment. The work emphasized correctness and reliability in automated test scenarios for Lakekeeper.
