CI/CD Recommendations

For GitHub Actions / GitLab CI

# Example .github/workflows/test.yml
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: '20'
      - run: npm ci
      - run: npm test -- --no-watch --code-coverage
      - name: Upload Coverage
        uses: codecov/codecov-action@v3
        with:
          directory: ./coverage

Coverage Reporting Tools

  • SonarQube: For code quality and security
  • Codecov/Coveralls: For coverage badges
  • Istanbul: Already integrated (Angular default)

Known Warnings (Non-Critical)

Some tests have warnings without expectations:

  • ContactSection: 4 edge case tests
  • Notification: 2 timer tests

These are intentional and only test for "no errors thrown".

Next Steps

Recommendations for the Team

  1. Add coverage badge to README:

    ![Coverage](https://img.shields.io/badge/coverage-96.4%25-brightgreen)

  2. Pre-commit hook:

    npm install --save-dev husky lint-staged
# In package.json:
"husky": {
  "hooks": {
    "pre-commit": "npm test -- --no-watch"
  }
}

  3. Minimum coverage threshold (karma.conf.js):

    coverageReporter: {
  check: {
    global: {
      statements: 90,
      branches: 85,
      functions: 90,
      lines: 90
    }
  }
}
