CI/CD Integration

GitHub Actions Example

name: Test Suite
on: [push, pull_request]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: '18'
      - run: npm ci
      - run: npm test -- --coverage
      - uses: codecov/codecov-action@v3

Known Limitations

1. npm audit: Requires internet connection for vulnerability checks
2. File System: Tests use temporary directories
3. Concurrency: Tests run in parallel
4. Environment: Requires Node.js 14+

Troubleshooting

Tests Timeout

Increase timeout in jest.config.js:

testTimeout: 15000  // 15 seconds

Module Not Found

Check paths in tsconfig.json:

moduleNameMapper: {
  '^@/(.*)$': '<rootDir>/src/$1',
}

Coverage Issues

Check which lines are uncovered:

npm test -- --coverage
open coverage/lcov-report/index.html

Documentation

• Test README: tests/README.md
• Test Utils: tests/test-utils.ts
• Sample Data: tests/fixtures/sampleData.ts
• Jest Config: jest.config.js

Next Steps

1. Run the test suite: npm test
2. Check coverage: npm test -- --coverage
3. Review coverage report: open coverage/lcov-report/index.html
4. Run specific test categories as needed
5. Add tests for new features
