### Test Statistics

- **Total Test Files**: 13
- **Total Test Methods**: ~115
- **Total Lines of Code**: ~1,500
- **Coverage**: 100% of API Standard components

### What Tests Verify

1. **Unified Response Format**
   - All responses include `success` field (true/false)
   - Success responses include `data` (single object) or `results` (list)
   - Error responses include `error` (message) and `errors` (field-specific)
   - All responses include `request_id` (UUID)

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

3. **Pagination**
   - Paginated responses include `count`, `next`, `previous`, `results`
   - Page size limits enforced (max 100)
   - Empty results handled correctly
   - Default page size (10) works correctly

4. **Error Handling**
   - All exceptions wrapped in unified format
   - Field-specific errors included in `errors` object
   - Debug info (traceback, view, path, method) in DEBUG mode
   - Request ID included in all error responses

5. **Permissions**
   - Role-based access control (viewer, editor, admin, owner, developer)
   - Tenant isolation (users can only access their account's data)
   - Site/sector scoping (users can only access their assigned sites/sectors)
   - Admin/system account bypass (full access)

6. **Rate Limiting**
   - Throttle headers present in all responses
   - Bypass logic for admin/developer/system account users
   - Bypass in DEBUG mode (for development)
   - Different throttle scopes (read, write, ai)
