Regression Testing

<default_to_action> When verifying changes don't break existing functionality:

  1. ANALYZE what changed (git diff, impact analysis)
  2. SELECT tests based on change + risk (not everything)
  3. RUN in priority order (smoke → selective → full)
  4. OPTIMIZE execution (parallel, sharding)
  5. MONITOR suite health (flakiness, execution time)

Quick Regression Strategy:

  • Per-commit: Smoke + changed code tests (5-10 min)
  • Nightly: Extended regression (30-60 min)
  • Pre-release: Full regression (2-4 hours)

Critical Success Factors:

  • Smart selection catches 90% of regressions in 10% of time
  • Flaky tests waste more time than they save
  • Every production bug becomes a regression test
