🚀 For Developers

Run Tests Locally

# All tests
npm test

# With coverage
npm test -- --no-watch --code-coverage

# Only specific tests
npm test -- --include='**/services/*.spec.ts'

View Coverage Report

After npm test -- --no-watch --code-coverage:

📚 Documentation

The project has the following documentation:

Main Documents (in .github/docs/ folder)

Component Documentation (in .github/docs/ folder)

Note: Generated documentation (/docs, /coverage) is ignored by Git (.gitignore).

🔧 CI/CD Integration

Recommendation for GitHub Actions

Create ../../.github/workflows/test.yml:

name: Test & Coverage

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3

      - name: Setup Node
        uses: actions/setup-node@v3
        with:
          node-version: '20'
          cache: 'npm'

      - name: Install Dependencies
        run: npm ci

      - name: Run Tests
        run: npm test -- --no-watch --code-coverage

      - name: Upload Coverage
        uses: codecov/codecov-action@v3
        with:
          directory: ./coverage
          fail_ci_if_error: true

Recommendation for GitLab CI

Create .gitlab-ci.yml:

stages:
  - test

test:
  stage: test
  image: node:20
  cache:
    paths:
      - node_modules/
  script:
    - npm ci
    - npm test -- --no-watch --code-coverage
  coverage: '/Lines\s*:\s*(\d+\.\d+)%/'
  artifacts:
    reports:
      coverage_report:
        coverage_format: cobertura
        path: coverage/cobertura-coverage.xml

🎨 Testing Best Practices (Used in Project)

1. Service Mocking

const serviceSpy = jasmine.createSpyObj('ServiceName', ['method1', 'method2'], {
  signal1: signal('value'),
  computed1: computed(() => 'value'),
});

2. Signal Testing

it('should update signal', () => {
  component.mySignal.set('new value');
  expect(component.mySignal()).toBe('new value');
});

3. Computed Testing

it('should compute value', () => {
  component.inputSignal.set('input');
  expect(component.computedValue()).toBe('computed-input');
});

4. Async Operations

it('should handle async', fakeAsync(() => {
  component.asyncMethod();
  tick(1000);
  expect(component.result()).toBe('done');
}));

⚠️ Known Warnings (Non-Critical)

Some tests have warnings without expectations:

  • ContactSection: 4 tests (edge cases - only test "no error")
  • Notification: 2 tests (timer tests - only test "no error")

These are intentional and only test that no errors are thrown.

👥 For Code Reviews

Checklist

  • ✅ All new components have .spec.ts files
  • ✅ Coverage stays above 90%
  • ✅ No tests with fdescribe or fit (only)
  • ✅ Mocks use signals where necessary
  • ✅ Accessibility tests (ARIA) present

Review Commands

# View coverage diff
npm test -- --no-watch --code-coverage

# Test only changed files
npm test -- --include='path/to/changed/**/*.spec.ts'

📞 Support

For questions about the test setup:

  1. See component documentation in .github/docs/ folder
  2. Look at existing .spec.ts files as examples
  3. Check TESTING-REPORT.md for details

✅ Next Steps

  1. Set up CI/CD: GitHub Actions or GitLab CI
  2. Coverage badges: Add to README.md
  3. Pre-commit hooks: Husky for automatic tests
  4. E2E tests (optional): Playwright or Cypress

Status: Ready for production deployment Last Test Run: December 15, 2025 - 823/823 tests passing ✅
