## Manyan fa'idodi na jarrabawar atomatik

```text
✓ CATCH BUGS EARLY — find defects during development, before users (cheaper to fix)
✓ PREVENT REGRESSIONS — tests catch when a change breaks existing functionality
  (run them after every change → safety net)
✓ CONFIDENCE TO CHANGE — refactor and add features knowing tests will catch breakage
  (without tests, changes are scary; with tests, you change freely)
✓ DOCUMENTATION — tests show how code is meant to be used and what it should do
✓ FAST FEEDBACK — automated tests run in seconds (vs slow, error-prone manual testing)
✓ Enable CI/CD — automated tests are the foundation of automated, safe delivery
```

## Jarrabawa ta atomatik da na hannu

```text
MANUAL testing → a human checks → slow, not repeatable, error-prone, doesn't scale
  (re-testing everything by hand after each change is impractical)
AUTOMATED testing → code checks code → fast, repeatable, consistent, runs constantly
  → run thousands of checks in seconds, every change, reliably
→ Automated tests make thorough, frequent testing FEASIBLE.

The cost to fix a bug GROWS the later it's found:
  caught while coding (cheap) << in testing << in production (expensive: users affected,
  emergency fixes, reputation, data issues)
→ Tests catch bugs early → save significant cost and pain.
