Quick Start

1. Run coverage report for your technology:
   • JavaScript/TypeScript: pnpm run test:coverage
   • Python: pytest --cov=. --cov-report=html
   • Java: ./gradlew jacocoTestReport
   • Go: go test -cover ./...
2. Review uncovered files and functions
3. Apply patterns from the references:
   • references/test-patterns.md - General test patterns
   • references/{technology}/test-patterns.md - Technology-specific patterns
4. Write tests for uncovered code paths
5. Re-run coverage to verify improvement
