Worked on the astropy/astropy repository to enhance the reliability of automated testing by addressing issues with tests that depend on remote data. Introduced logic using Python and pytest to ensure that tests requiring network connectivity only execute when such connectivity is available, thereby preventing build failures in offline CI environments. Consolidated tests related to future or uncovered time ranges under a unified offline-safe approach, streamlining test management and reducing CI noise. This work improved the maintainability of the test suite and supported more robust continuous integration workflows, leveraging skills in CI/CD, Python, and advanced testing practices throughout the process.
