During November 2024, Celeste focused on improving test data integrity for the openreview/openreview-py repository, specifically within the ARR v1 test suite. She addressed inconsistencies in reviewer username and ID mappings, ensuring accurate reviewer assignments and group memberships across test cases. Using Python and her expertise in testing, Celeste reverted a previous ethics reviewer data patch to restore baseline test expectations, which stabilized test reliability and reduced CI flakiness. Her work enhanced traceability of test data changes, supporting future audits and onboarding. Although the period involved no new features, her targeted bug fix contributed to more robust and maintainable test workflows.
