## Ganyaye masu karamin tsarin gwaji

```text
✗ 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
```

## Ganyaye na tsarin da dabarun mahimmanci

```text
✗ ICE CREAM CONE → mostly slow E2E/manual, few unit tests → slow, brittle, expensive suite
✗ INTERDEPENDENT tests / shared mutable state → order-dependent, flaky, fragile
✗ Testing the FRAMEWORK / trivial code → low value; testing what doesn't need testing
✗ Chasing COVERAGE numbers → low-value tests written just to hit a percentage
✗ Slow tests → discourage running them → defeats fast-feedback value
```

## Ganyaye na tsari

```text
✗ Writing tests as an afterthought (or never) → poor coverage, untestable design
✗ Ignoring failing/flaky tests → the suite becomes untrusted/useless
✗ Not maintaining tests (test code rot) → tests are code; they need care
→ Recognize these and steer toward: behavior-focused, isolated, fast, meaningful,
  pyramid-shaped, maintained tests.
```
