## Continuous Integration
|
|
|
|
### Pre-commit Checks
|
|
|
|
```bash
|
|
npm test -- test/unit/ --verbose
|
|
```
|
|
|
|
### Pre-push Checks
|
|
|
|
```bash
|
|
npm test -- --coverage
|
|
```
|
|
|
|
### CI/CD Pipeline
|
|
|
|
```bash
|
|
npm test -- --coverage --watchAll=false
|
|
```
|
|
|
|
---
|
|
|
|
## Known Test Limitations
|
|
|
|
1. **Mock Inquirer**: Uses jest.spyOn for prompt verification (actual CLI not tested)
|
|
2. **File System**: Uses temporary directories (safe from actual file corruption)
|
|
3. **Network**: No network dependencies
|
|
4. **External Services**: None required
|
|
|
|
---
|
|
|
|
## Next Steps
|
|
|
|
1. ✅ Write tests (COMPLETE)
|
|
2. Implement configuration loader
|
|
3. Implement update detection
|
|
4. Implement question skipping
|
|
5. Run all tests and verify pass
|
|
6. Add to CI/CD pipeline
|
|
7. Monitor test coverage
|
|
8. Maintain tests with code changes
|
|
|
|

|
|
|
|
## Test Maintenance
|
|
|
|
### Adding New Tests
|
|
|
|
1. Place in appropriate test file (unit or integration)
|
|
2. Follow naming convention: `it('should [expected behavior]')`
|
|
3. Include beforeEach/afterEach cleanup
|
|
4. Add to test count in this document
|
|
5. Update success criteria if applicable
|
|
|
|
### Updating Tests
|
|
|
|
1. Keep tests focused and independent
|
|
2. Use descriptive names
|
|
3. Add comments for complex assertions
|
|
4. Update this document with changes
|
|
5. Ensure no duplication
|
|
|
|
### Debugging Tests
|
|
|
|
```bash
|
|
# Run single test file
|
|
npm test -- test/unit/config-loader.test.js
|
|
|
|
# Run with verbose output
|
|
npm test -- --verbose
|
|
|
|
# Run with debugging
|
|
node --inspect-brk node_modules/.bin/jest --runInBand test/unit/config-loader.test.js
|
|
```
