## Part 8: Continuous Testing Strategy

### Pre-Commit Hooks (5s)
```bash
./rtm check
├── Lint check (ESLint, Biome)
├── Type check (TypeScript, mypy)
├── Format check
└── Quick unit test (affected only)
```

### Branch Validation (5-10 min)
```bash
./rtm test:branch
├── All unit tests (frontend, backend)
├── Type checking (strict mode)
├── Lint & format enforcement
├── Security scanning (basic)
└── Coverage enforcement (>80%)
```

### PR Validation (10-15 min)
```bash
./rtm test:pr
├── Full test suite (all layers)
├── Performance regression check
├── Coverage enforcement
├── Security scanning (SAST)
├── Accessibility validation
└── API contract validation
```

### Merge Validation (15-20 min)
```bash
./rtm test:merge
├── Complete test suite
├── Chaos engineering baseline
├── Production readiness check
├── Documentation completeness
└── Security sign-off
```
