Worked on the sonic-net/sonic-mgmt repository to address reliability issues in automated testing by fixing a persistent flakiness in techsupport file deletion validation. Focused on replacing brittle, hardcoded file expectations with dynamic, Python-based logic that queries actual filesystem states after cleanup, ensuring deterministic validation across different environments and file sizes. Leveraged Python scripting, test automation, and filesystem introspection to implement these changes, which improved CI stability and reduced intermittent failures, particularly in dualtor topologies. The solution enabled faster triage and more robust automation, with tests now consistently passing under varied conditions, reflecting a methodical approach to software testing challenges.
