Quick Start
- 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./...
- Review uncovered files and functions
- Apply patterns from the references:
- references/test-patterns.md - General test patterns - references/{technology}/test-patterns.md - Technology-specific patterns
- Write tests for uncovered code paths
- Re-run coverage to verify improvement
