A developer shares how a production incident traced to a six-week-old mock file revealed a fundamental flaw in their regression testing approach: manually maintained mocks silently decay as downstream services evolve, creating false confidence in green pipelines. The fix was shifting from specification-based mocks to traffic-captured mocks using Keploy, which automatically keeps test baselines aligned with current service behavior. The core lesson is that deployment confidence comes not from experience alone, but from genuinely understanding what your regression suite is actually verifying.
