Worked on test stabilization and cross-hardware validation for configuration override behavior in the sonic-net/sonic-mgmt repository. Focused on improving test reliability by updating configuration override tests to ignore volatile FEATURE and PORT tables that change during runtime, ensuring consistent results across diverse hardware platforms. Enhanced diagnostics by aggregating all configuration mismatches into a single report, allowing for more comprehensive analysis rather than failing on the first error. Utilized Python, pytest, and network automation skills to address a key bug, resulting in reduced flaky failures and improved CI stability. The work contributed to faster, more reliable validation of configuration overrides in automated testing.
