Worked on the Aleph-Alpha/aleph-alpha-client repository to unify the test suite, focusing on improving continuous integration reliability and coverage. Refactored the test infrastructure by removing the system_test marker, allowing all tests to run uniformly within the CI pipeline. This change streamlined the CI configuration and broadened automated test coverage, making the testing process more maintainable and efficient. Demonstrated skills in Python, Pytest, and general testing practices, with careful attention to commit traceability for easier code review and future audits. No major bugs were addressed during this period, with efforts concentrated on enhancing test reliability and maintainability through infrastructure improvements.
