Worked on the openreview/openreview-py repository to address test data integrity issues within the ARR v1 test suite. Focused on correcting reviewer username and ID mappings to ensure accurate reviewer assignments and group memberships across automated test cases. Utilized Python and testing frameworks to revert a previous ethics reviewer data patch, restoring baseline test expectations and improving the reliability of continuous integration feedback. Documented all test data changes to support future audits and onboarding. The work enhanced traceability and reduced flakiness in test runs, contributing to a more stable and maintainable testing environment for ongoing development and quality assurance.
