పరీక్ష చేయడంలో సాధారణ యాంటీ-పాటర్‌న్‌లు ఏవి, వాటిని ఎలా నివారించాలి?

✗ TESTING IMPLEMENTATION DETAILS → tests coupled to internals → break on every refactor
  (brittle) → test BEHAVIOR/outcomes instead
✗ FLAKY tests → intermittent failures erode trust → people ignore failures (real ones too)
✗ OVER-MOCKING → mocking everything → tests verify mock interactions, not real behavior;
  brittle and give false confidence
✗ Tests with NO meaningful assertions → run code but verify nothing (false coverage)
✗ GIANT tests checking many things → unclear what failed; hard to maintain
