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 test stability and CI feedback by ensuring that health checks validated both the HTTP status and the presence of the text 'status ok' in the response body. Using Shell scripting and leveraging CI/CD and testing skills, Chrono improved the accuracy and readability of health endpoint validations. This approach reduced flaky test runs and provided more robust health signals, addressing reliability concerns in automated testing workflows and strengthening the overall quality of the repository’s health checks.
