Coverage Improvements in This PR

Before

  • Overall statement coverage: 35.86%
  • Logger coverage: 25%
  • No coverage infrastructure
  • No coverage thresholds
  • No HTML reports

After

  • Overall statement coverage: 38.39% (↑ 2.53%)
  • Logger coverage: 100% (↑ 75%)
  • Coverage thresholds enforced
  • Multiple report formats (HTML, LCOV, JSON)
  • Comprehensive testing documentation

Test Suite Statistics

  • Total Test Suites: 6 passed
  • Total Tests: 135 passed
  • Test Execution Time: ~4.4 seconds

Test Files

  1. logger.test.ts - 33 tests (NEW)
  2. squid-config.test.ts - 41 tests
  3. cli-workflow.test.ts - 2 tests (100% coverage)
  4. host-iptables.test.ts - 12 tests
  5. docker-manager.test.ts - 23 tests
  6. cli.test.ts - 24 tests

Coverage Reports

After running npm run test:coverage, reports are available in multiple formats:

  • HTML Report: coverage/index.html (open in browser)
  • LCOV Report: coverage/lcov.info (CI/CD integration)
  • JSON Summary: coverage/coverage-summary.json (programmatic access)
  • Terminal Output: Displayed after test run

Areas for Future Improvement

High Priority

  1. cli.ts (0% coverage)

    • Entry point testing
    • CLI argument parsing
    • Signal handling
    • Error cases

  2. docker-manager.ts (18% coverage)

    • Container lifecycle functions
    • Error handling paths
    • Log parsing logic
    • Cleanup operations

Medium Priority

  1. host-iptables.ts (83.63% coverage)
    • Edge cases in remaining 16.37%
    • Error conditions
    • Cleanup scenarios

How to View Coverage

Terminal

npm run test:coverage

HTML Report

npm run test:coverage
open coverage/index.html  # macOS
xdg-open coverage/index.html  # Linux

Watch Mode

npm run test:watch

Coverage Thresholds

Configured in jest.config.js:

coverageThreshold: {
  global: {
    branches: 30,
    functions: 35,
    lines: 38,
    statements: 38,
  },
}

Tests will fail if coverage drops below these thresholds.

Integration with CI/CD

The coverage reports (especially LCOV format) can be integrated with:

  • GitHub Actions (via coverage badges)
  • Codecov
  • Coveralls
  • SonarQube
  • Other CI/CD tools

Example GitHub Actions workflow:

- name: Run tests with coverage
  run: npm run test:coverage

- name: Upload coverage to Codecov
  uses: codecov/codecov-action@v3
  with:
    files: ./coverage/lcov.info

Summary

This PR establishes a solid testing infrastructure for the project with:

✅ 100% coverage for 3 core modules (logger, squid-config, cli-workflow) ✅ Coverage thresholds to prevent regression ✅ Multiple report formats for different use cases ✅ Comprehensive documentation (TESTING.md) ✅ All tests passing (135/135)

The foundation is now in place for continuous improvement of test coverage across the remaining modules.
