## What Tests Verify

1. **Unified Response Format**
   - All responses include `success` field
   - Success responses include `data` or `results`
   - Error responses include `error` and `errors`
   - All responses include `request_id`

2. **Status Codes**
   - Correct HTTP status codes (200, 201, 400, 401, 403, 404, 429, 500)
   - Proper error messages for each status code

3. **Pagination**
   - Paginated responses include `count`, `next`, `previous`, `results`
   - Page size limits enforced
   - Empty results handled correctly

4. **Error Handling**
   - All exceptions wrapped in unified format
   - Field-specific errors included
   - Debug info in DEBUG mode

5. **Permissions**
   - Role-based access control
   - Tenant isolation
   - Admin/system account bypass

6. **Rate Limiting**
   - Throttle headers present
   - Bypass logic for admin/system accounts
   - Bypass in DEBUG mode

## Running Tests

```bash
# Run all tests
python manage.py test igny8_core.api.tests --verbosity=2

# Run specific test file
python manage.py test igny8_core.api.tests.test_response

# Run specific test class
python manage.py test igny8_core.api.tests.test_response.ResponseHelpersTestCase
```

## Next Steps

1. Run tests in Docker environment
2. Verify all tests pass
3. Add to CI/CD pipeline
4. Monitor test coverage
5. Add performance tests if needed
