bun run test:contracts:watch     # Watch mode
bun run test:contracts:generate  # Generate pacts
bun run test:contracts:coverage  # Tests + coverage
```

### CI/CD

- Workflow: `.github/workflows/contract-tests.yml`
- Runs on: PRs, pushes to main/develop
- Stages: Consumer → Provider → Publish → Coverage

## 🎓 Learning Path

### Beginner

1. Read [QUICK_START.md](./QUICK_START.md)
2. Run existing tests
3. Read test examples in `consumer/`
4. Write your first consumer test

### Intermediate

1. Read [README.md](./README.md)
2. Add provider state handlers
3. Write comprehensive test suites
4. Use advanced matchers

### Advanced

1. Read [VERSIONING.md](./VERSIONING.md)
2. Manage breaking changes
3. Setup Pact Broker
4. Optimize CI/CD pipeline

## 🐛 Troubleshooting

Quick fixes for common issues:

| Problem | Solution |
|---------|----------|
| Consumer tests fail | Check mock server port 8080 |
| Provider tests fail | Verify state handlers exist |
| No pacts generated | Check `afterAll` calls `teardownPact()` |
| Port conflict | Change mock server port in setup.ts |
| Database errors | Check TEST_DB_* environment variables |

See [README.md](./README.md#troubleshooting) for detailed troubleshooting.
