Test Coverage

Analyze test coverage and generate missing tests:

  1. Run tests with coverage: npm test --coverage or pnpm test --coverage

  2. Analyze coverage report (coverage/coverage-summary.json)

  3. Identify files below 80% coverage threshold

  4. For each under-covered file:

    • Analyze untested code paths
    • Generate unit tests for functions
    • Generate integration tests for APIs
    • Generate E2E tests for critical flows
  5. Verify new tests pass

  6. Show before/after coverage metrics

  7. Ensure project reaches 80%+ overall coverage

Focus on:

  • Happy path scenarios
  • Error handling
  • Edge cases (null, undefined, empty)
  • Boundary conditions
