Gabri Martinez focused on backend reliability for the CustomerAutoZoneSelfService/cazss-backend repository during June 2025, addressing test instability rather than delivering new features. Gabri refactored Java unit tests by removing the Disabled annotation and introducing a mock for the EndpointsRepository, which resolved persistent test failures and improved the accuracy of the test suite. This backend development work reduced continuous integration noise and provided faster, more reliable feedback for future code changes. By prioritizing test stability and refactoring, Gabri laid a stronger foundation for upcoming backend enhancements, ensuring safer deployments and accelerating the pace of future feature delivery within the project.
