# 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
