Worked on enhancing the reliability of the Eppo-exp/sdk-test-data repository by addressing a critical bug in the hashing and encoding logic for feature flag data. Focused on data validation and testing, the work involved implementing robust handling for empty string flag values, ensuring that the test suite accurately reflects edge case scenarios. By expanding test coverage and refining the encoding processes using JSON, the developer improved both the resilience and maintainability of the codebase. These efforts contributed to greater data integrity and reliability in feature flag scenarios, supporting more dependable test outcomes without introducing new features during the reported period.
