Worked on the IAS-Astrophysics/athenak repository to enhance the reliability and accuracy of its continuous integration and test automation workflows. Focused on Python scripting and CI/CD, the developer addressed two critical bugs by ensuring that non-zero exit codes from pytest test suites were correctly propagated to CI results, allowing failures to be accurately reflected and reducing silent regressions. Additionally, they improved test infrastructure by removing unnecessary build directory creation and enhancing error logging for test commands. These changes strengthened the feedback loop for developers, improved traceability, and contributed to more stable and maintainable automated testing processes within the project.
