- ✅ Protocol restriction (http/https only)
|
||||
|
||||
### Error Handling
|
||||
- ✅ Graceful handling of malformed configurations
|
||||
- ✅ Specific error messages for debugging

|
||||
|
||||
## Test Patterns Used
|
||||
|
||||
### Arrange-Act-Assert
|
||||
All tests follow the clear AAA pattern for maintainability and readability.
|
||||
|
||||
### Comprehensive Mocking
|
||||
- Logger mocking for isolation
|
||||
- Environment variable mocking for clean state
|
||||
- Dependency injection for testability
|
||||
|
||||
### Data-Driven Testing
|
||||
- Parameterized tests for URL patterns
|
||||
- Truth table testing for configuration logic
|
||||
- Matrix testing for scenario combinations
|
||||
|
||||
### Edge Case Coverage
|
||||
- Boundary value testing (ports, IP ranges)
|
||||
- Invalid input testing (malformed URLs, empty strings)
|
||||
- Security testing (XSS, injection attempts)
|
||||
|
||||
## Running the Tests
|
||||
|
||||
```bash
|
||||
# Run all multi-tenant tests
|
||||
npm test tests/unit/mcp/multi-tenant-tool-listing.test.ts
|
||||
npm test tests/unit/types/instance-context-multi-tenant.test.ts
|
||||
npm test tests/unit/http-server/multi-tenant-support.test.ts
|
||||
npm test tests/unit/multi-tenant-integration.test.ts
|
||||
|
||||
# Run with coverage
|
||||
npm run test:coverage
|
||||
|
||||
# Run specific test patterns
|
||||
npm test -- --grep "multi-tenant"
|
||||
```
|
||||
|
||||
## Test Maintenance Notes
|
||||
|
||||
### Mock Updates
|
||||
When updating the logger or other core utilities, ensure mocks are updated accordingly.
|
||||
|
||||
### Environment Variables
|
||||
Tests properly isolate environment variables to prevent cross-test pollution.
|
||||
|
||||
### Real-World Patterns
|
||||
URL validation tests are based on actual n8n deployment patterns and should be updated as new deployment methods are supported.
|
||||
|
||||
### Security Tests
|
||||
Security-focused tests should be regularly reviewed and updated as new attack vectors are discovered.
|
||||
|
||||
## Future Test Enhancements
|
||||
|
||||
### Performance Testing
|
||||
- Session management under load
|
||||
- Memory usage during high tenant count
|
||||
- Configuration validation performance
|
||||
|
||||
### End-to-End Testing
|
||||
- Full HTTP request/response cycles
|
||||
- Multi-tenant workflow execution
|
||||
- Session persistence across requests
|
||||
|
||||
### Integration Testing
|
||||
- Database adapter integration with multi-tenant contexts
|
||||
- MCP protocol compliance with dynamic tool sets
|
||||
- Error propagation across component boundaries
