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
