Find what the developer forgot. Hunt bugs before they hunt users.
"Don't guess. Investigate systematically. Fix the root cause, not the symptom."

┌─────────────────────────────────────────────────────────────┐
│ PHASE 1: REPRODUCE │
│ • Get exact reproduction steps │
│ • Determine reproduction rate (100%? intermittent?) │
│ • Document expected vs actual behavior │
└───────────────────────────┬─────────────────────────────────┘

┌─────────────────────────────────────────────────────────────┐
│ PHASE 2: ISOLATE │
│ • When did it start? What changed? │
│ • Which component is responsible? │
│ • Create minimal reproduction case │
└───────────────────────────┬─────────────────────────────────┘

┌─────────────────────────────────────────────────────────────┐
│ PHASE 3: UNDERSTAND (Root Cause) │
│ • Apply "5 Whys" technique │
│ • Trace data flow │
│ • Identify the actual bug, not the symptom │
└───────────────────────────┬─────────────────────────────────┘

┌─────────────────────────────────────────────────────────────┐
│ PHASE 4: FIX & VERIFY │
│ • Fix the root cause │
│ • Verify fix works │
│ • Add regression test │
│ • Check for similar issues │

Functions, logic
| Error Type | Investigation Approach |
|---|---|
| Runtime Error | Read stack trace, check types and nulls |
| Logic Bug | Trace data flow, compare expected vs actual |
| Performance | Profile first, then optimize |
| Intermittent | Look for race conditions, timing issues |
| Memory Leak | Check event listeners, closures, caches |
| Symptom | First Steps |
|---|---|
| "It crashes" | Get stack trace, check error logs |
| "It's slow" | Profile, don't guess |
| "Sometimes works" | Race condition? Timing? External dependency? |
| "Wrong output" | Trace data flow step by step |
| "Works locally, fails in prod" | Environment diff, check configs |
WHY is the user seeing an error?
→ Because the API returns 500.
WHY does the API return 500?
→ Because the database query fails.
WHY does the query fail?
→ Because the table doesn't exist.
WHY doesn't the table exist?
→ Because migration wasn't run.
WHY wasn't migration run?
→ Because deployment script skips it. ← ROOT CAUSE
| Step | Purpose |
|---|---|
| Arrange | Set up test data |
| Act | Execute code |
| Assert | Verify outcome |
describe('UserService', () => {
it('should create user with valid data', async () => {
// Arrange
const userData = { email: 'test@example.com', name: 'Test' };
// Act
const user = await userService.create(userData);
// Assert
expect(user.id).toBeDefined();
expect(user.email).toBe(userData.email);
});
});
| Area | Target |
|---|---|
| Critical paths | 100% |
| Business logic | 80%+ |
| Utilities | 70%+ |
| UI layout | As needed |
| ❌ Don't | ✅ Do |
|---|---|
| Random changes hoping to fix | Systematic investigation |
| Ignoring stack traces | Read every line carefully |
| "Works on my machine" | Reproduce in same environment |
| Fixing symptoms only | Find and fix root cause |
| No regression test | Always add test for the bug |
| Multiple changes at once | One change, then verify |
| Test implementation | Test behavior |

Remember: Debugging is detective work. Testing is insurance. Follow the evidence, not your assumptions.
