Worked on enhancing the reliability of location-based testing for the qor5/admin repository by developing a feature that automates GeoIP2 test data management. Introduced the ensureTestData function in Go to automatically download the required test database when missing, incorporating robust error handling and automatic directory creation to strengthen the backend testing process. This approach reduced manual setup, minimized flaky tests, and improved continuous integration stability. The work focused on backend development and testing, laying the foundation for future data-driven testing and clearer documentation of failure scenarios, ultimately streamlining test data management and increasing the resilience of the location testing suite.
