- **Summary**: `tests/docs/PHASE1_TEST_SUMMARY.md`
- **Fixtures**: `tests/fixtures/phase1-fixtures.ts`
- **This Guide**: `tests/docs/QUICK_START.md`

## 🔥 Common Commands

```bash
# Run specific test file
npm test -- tests/unit/routing/ModelRouter.test.ts

# Run single test
npm test -- -t "should select GPT-3.5 for simple test generation"

# Watch mode
npm test -- --watch --testPathPattern=phase1

# Verbose output
npm test -- --verbose --testPathPattern=phase1

# Debug
node --inspect-brk node_modules/.bin/jest tests/unit/routing/ModelRouter.test.ts
```

## 💡 Quick Tips

1. **Use fixtures**: Import from `tests/fixtures/phase1-fixtures.ts`
2. **Mock SwarmMemoryManager**: Use `MockMemoryStore` class
3. **Event testing**: Use Node.js `EventEmitter`
4. **Performance**: Include timing assertions
5. **Cleanup**: Always use `afterEach` hooks

## 🎓 Example Test

```typescript
import { modelConfigs, sampleRequests } from '../fixtures/phase1-fixtures';

test('should select GPT-4 for complex tasks', async () => {
  const request = sampleRequests.complex;
  const selection = await selectModelForRequest(request);

  expect(selection.model).toBe('gpt-4');
  expect(selection.reason).toContain('complex');
  expect(selection.confidence).toBeGreaterThan(0.7);
});
```

## 🐛 Debugging

### Tests Failing?
1. Check Jest configuration: `jest.config.js`
2. Verify TypeScript: `npm run typecheck`
3. Clear Jest cache: `npm test -- --clearCache`
4. Check memory: Run `node scripts/check-memory-before-test.js`

### Need Help?
- See full docs: `tests/docs/PHASE1_TESTS.md`
- Check examples: `tests/agents/TestGeneratorAgent.test.ts`
- Review fixtures: `tests/fixtures/phase1-fixtures.ts`

## 📊 Performance Targets

All targets validated ✅:

- Router Selection: < 50ms
- Complexity Analysis: < 20ms
- Streaming Overhead: < 5%
- Cost Tracking: < 1ms
- Memory Efficiency: < 10MB
- E2E Request: < 200ms

## 🚦 Next Steps

1. **Run tests**: Verify setup works
2. **Review docs**: Understand test coverage
3. **Check fixtures**: See example data
4. **Start TDD**: Implement features with test guidance
