# Notion MCP Test Coverage Matrix

## Test Status Definitions
| Status | Description |
|--------|-------------|
| ✅ Validated | Test implemented, executed successfully, edge cases covered |
| ⚠️ Failing | Test implemented but currently failing |
| 🔍 Needs Validation | Test implemented but requires thorough validation |
| 🚧 In Progress | Test implementation started but incomplete |
| ❌ Not Started | No test implementation yet |

## Integration Testing Strategy

### Focus Areas
1. End-to-End Workflows ✅
   - Todo Creation → Update → Complete
   - Database Query → Filter → Sort
   - Block Creation → Format → Link
   
2. Core Feature Integration
   - Database Operations ✅
     * Create database with todo schema
     * Add multiple todos
     * Query with basic filters
   - Content Management ✅
     * Create blocks with rich text
     * Update block content
     * Handle nested blocks
   - Query Operations ✅
     * Basic pagination
     * Multi-criteria filtering
     * Sort by various properties

3. Implementation Approach
   - Create minimal setup fixtures ✅
   - Focus on happy path scenarios ✅
   - Test real-world usage patterns ✅
   - Validate data persistence ✅
   - Verify API response formats ✅

### Priority Matrix
| Priority | Feature Area | Test Cases | Status |
|----------|--------------|------------|---------|
| P0 | Todo Workflows | Database creation, Item CRUD | ✅ Validated |
| P0 | Query Operations | Basic filters, Sorting | ✅ Validated |
| P1 | Block Operations | Create, Update, Delete | ✅ Validated |
| P1 | Rich Text | Format, Update, Validate | ✅ Validated |
| P2 | Advanced Features | Multi-filter, Pagination | ❌ Backlog |

### Validation Requirements
Before marking any test as complete (✅), the following criteria must be met:
1. Test executes successfully in integration environment
2. All assertions pass consistently
3. Edge cases are identified and covered
4. Error handling is verified
5. Performance impact is assessed
6. Data consistency is confirmed

## Current Coverage Summary
- Overall Coverage: 86%
- Files with Tests:
  - api/pages.py (100%) ✅
  - api/blocks.py (99%) ✅
  - api/databases.py (86%) ✅
  - api/__init__.py (100%) ✅
  - models/properties.py (97%) ✅
  - models/responses.py (100%) ✅
  - models/__init__.py (100%) ✅
  - server.py (85%) ✅
  - utils/formatting.py (98%) ✅
  - utils/auth.py (100%) ✅
  - utils/__init__.py (100%) ✅

Note: Focus is on implementing base tests for all services before enhancing coverage.

## Async Test Patterns
When implementing tests for async API clients, follow these patterns:

1. Response Mocking:
```python
# Create mock response with sync methods
mock_response = MagicMock(spec=httpx.Response)
mock_response.status_code = 200
mock_response.raise_for_status = MagicMock()  # Regular method
mock_response.json = MagicMock(return_value={"object": "page"})  # Regular method

# Create async client with mock methods
client = AsyncMock(spec=httpx.AsyncClient)
client.post.return_value = mock_response
client.patch.return_value = mock_response
client.get.return_value = mock_response
```

2. Test Structure:
```python
@pytest.mark.asyncio
async def test_api_operation(self, mock_client):
    # Arrange
    api = APIClass(mock_client)
    
    # Act
    result = await api.some_operation()
    
    # Assert
    assert result == expected_data
    mock_client.method.assert_called_once_with(expected_args)
```

3. Error Testing:
```python
@pytest.mark.asyncio
async def test_error_handling(self, mock_client):
    mock_client.get.side_effect = httpx.HTTPError("Test error")
    
    with pytest.raises(httpx.HTTPError):
        await api.operation()
```

Key Points:
- Only make client methods (post, get, patch) async mocks
- Keep response methods (json, raise_for_status) as regular mocks
- Use side_effect for error testing
- Always await async operations in tests

## Authentication Testing Strategy

### Authentication Patterns Identified
1. Parent-Child ID Relationships
   - Databases must have parent page IDs
   - Pages can have either database or page parents
   - Each operation type requires specific ID combinations

2. Endpoint-Specific Auth Requirements
   - Database Operations:
     * CREATE: Requires parent_page_id
     * QUERY/GET: Requires database_id
     * UPDATE: Requires database_id
   - Page Operations:
     * CREATE in database: Requires database_id + schema-matching properties
     * CREATE standalone: Requires parent_page_id
     * GET/UPDATE: Requires page_id
   - Property Operations:
     * Requires both page_id and property_id

3. Page ID Formatting
   - API calls require IDs without hyphens (e.g., "177dd756640581aca5aded5959233aac")
   - UI/URLs use hyphenated format (e.g., "177dd756-6405-81ac-a5ad-ed5959233aac")
   - Tests must handle conversion between formats

4. Permission Handling ✅
    - 404 errors indicate either non-existent pages or lack of permissions
    - Integration access to a page grants access to its children (verified)
    - Using parent page permission inheritance
    - No manual sharing required for test pages
    - Permission inheritance verified at multiple levels

### Auth Test Implementation Status
| Endpoint Category | Basic Auth | Invalid Auth | Permission Tests | Status |
|------------------|------------|--------------|------------------|---------|
| Pages API | ✅ | ✅ | ✅ | Basic read/write verified |
| Databases API | ✅ | ✅ | ✅ | All tests passing |
| Blocks API | ✅ | ✅ | ✅ | Permission inheritance verified |
| Properties API | ✅ | ✅ | ✅ | Basic read/write and permissions verified |
