72-136: LGTM: Factory tests are well-structured with good coverage.Your tests for the CarPartFactory cover all the important scenarios:
- Creating different part types
- Custom options for each part type
- Error handling for invalid inputs
Consider adding one additional test to verify that options not relevant to a specific part type are ignored (e.g., passing 'material' to a door creation should not affect the door).
test('should ignore options not relevant to the part type', () => { const door = factory.createPart({ partType: 'door', material: 'leather', // This should be ignored for a door color: 'yellow' }); expect(door instanceof CarDoor).toBe(true); expect(door.color).toBe('yellow'); expect(door.material).toBeUndefined(); });
1-137: Consider adding missing test coverage for edge cases.While your test suite covers the basic functionality well, consider adding tests for these edge cases:
- Testing with null/undefined property values:
test('should handle null/undefined properties correctly', () => { const door = new CarDoor({ color: null, hasPowerWindows: undefined }); expect(door.color).toBe('red'); // Should use default expect(door.hasPowerWindows).toBe(true); // Should use default });
- Testing with unexpected property types:
test('should handle unexpected property types', () => { const seat = new CarSeat({ color: 123, isReclinable: 'yes' }); // Define expected behavior based on implementation });🧰 Tools

11-40: LGTM: CarDoor constructor tests look comprehensive.These tests cover creation with default options, custom options, and partial overrides. Good job including different scenarios to ensure the constructor behaves correctly.
42-70: LGTM: CarSeat constructor tests follow the same pattern and are complete.Good consistency in your test approach between the different components. The tests properly verify default values, custom options, and partial overrides.

Replace eval() with a safer import mechanism.
Using eval() to import code exposes your application to security risks and performance issues. Even in a test environment, this approach is not recommended.
Consider using one of these safer alternatives:
- const fs = require('fs');
- const path = require('path');
-
- // Import the factory pattern code
- // Note: In a real project, you would use proper imports
- // This approach is used because we're testing a standalone file
- const filePath = path.join(__dirname, 'factory-pattern.js');
- eval(fs.readFileSync(filePath, 'utf8'));
+ // Option 1: Use require directly
+ const { CarDoor, CarSeat, CarPartFactory } = require('./factory-pattern');
+
+ // Option 2: If CommonJS modules aren't supported in the target file
+ // Refactor factory-pattern.js to use module.exports and then require itIf you need to keep the current file structure, at minimum use Function constructor instead of eval:
const factoryCode = fs.readFileSync(filePath, 'utf8');
const factoryModule = new Function('module, exports', factoryCode + '; return module.exports;')({exports: {}}, {});
const { CarDoor, CarSeat, CarPartFactory } = factoryModule;🧰 Tools
