During November 2024, Chrono contributed to the fatec-20245/fatec-5sem repository by developing a more reliable catalog health check endpoint. The work focused on enhancing the endpoint’s validation logic to assert both the HTTP status and the presence of the text 'status ok' in the response body, addressing the need for more robust health signals. Chrono improved the stability and accuracy of health-check tests, which reduced flaky test runs and provided clearer CI feedback. This feature was implemented using Shell scripting and leveraged CI/CD and testing best practices, reflecting a focused and methodical approach to improving service reliability.
