# Database Layer Unit Tests
|
||||
|
||||
This directory contains comprehensive unit tests for the database layer components of n8n-mcp.
|
||||
|
||||
## Test Coverage
|
||||
|
||||
### node-repository.ts - 100% Coverage ✅
|
||||
- `saveNode` method with JSON serialization
|
||||
- `getNode` method with JSON deserialization
|
||||
- `getAITools` method
|
||||
- `safeJsonParse` private method
|
||||
- Edge cases: large JSON, boolean conversion, invalid JSON handling
|
||||
|
||||
### template-repository.ts - 80.31% Coverage ✅
|
||||
- FTS5 initialization and fallback
|
||||
- `saveTemplate` with sanitization
|
||||
- `getTemplate` and `getTemplatesByNodes`
|
||||
- `searchTemplates` with FTS5 and LIKE fallback
|
||||
- `getTemplatesForTask` with task mapping
|
||||
- Template statistics and maintenance operations
|
||||
- Uncovered: Some error paths in FTS5 operations
|
||||
|
||||
### database-adapter.ts - Tested via Mocks
|
||||
- Interface compliance tests
|
||||
- PreparedStatement implementation
|
||||
- Transaction support
|
||||
- FTS5 detection logic
|
||||
- Error handling patterns
|
||||
|
||||
## Test Strategy
|
||||
|
||||
The tests use a mock-based approach to:
|
||||
1. Isolate database operations from actual database dependencies
|
||||
2. Test business logic without requiring real SQLite/sql.js
|
||||
3. Ensure consistent test execution across environments
|
||||
4. Focus on behavior rather than implementation details
|
||||
|
||||
## Key Test Files
|
||||
|
||||
- `node-repository-core.test.ts` - Core NodeRepository functionality
|
||||
- `template-repository-core.test.ts` - Core TemplateRepository functionality
|
||||
- `database-adapter-unit.test.ts` - DatabaseAdapter interface and patterns
|
||||
|
||||
## Running Tests
|
||||
|
||||
```bash
|
||||
# Run all database tests
|
||||
npm test -- tests/unit/database/
|
||||
|
||||
# Run with coverage
|
||||
npm run test:coverage -- tests/unit/database/
|
||||
|
||||
# Run specific test file
|
||||
npm test -- tests/unit/database/node-repository-core.test.ts
|
||||
```
|
||||
|
||||
## Mock Infrastructure
|
||||
|
||||
The tests use custom mock implementations:
|
||||
- `MockDatabaseAdapter` - Simulates database operations
|
||||
- `MockPreparedStatement` - Simulates SQL statement execution
|
||||
- Mock logger and template sanitizer for external dependencies
|
||||
|
||||
This approach ensures tests are fast, reliable, and maintainable.
