About

This Claude Skill automatically generates and validates unit, integration, and E2E tests to achieve comprehensive code coverage. It analyzes modified source files, creates appropriate tests using Jest and Playwright, and enforces a minimum 85% coverage with no failing tests. Use it when adding new features, when tests fail, or to improve coverage in your project.

  • "test fail"
  • "añadir tests"
  • "coverage" used_by:
  • front-end-dev
  • back-end-dev
  • test-engineer steps:
  • paso1: "Analizar archivos modificados en src/ para identificar componentes/servicios nuevos o modificados"
  • paso2: "Generar tests unitarios usando Jest con mocks apropiados (sin datos reales)"
  • paso3: "Generar tests de integración para flujos clave (auth, API, workers)"
  • paso4: "Generar tests E2E con Playwright para UI cuando aplique"
  • paso5: "Ejecutar npm test -- --coverage para validar cobertura"
  • paso6: "Verificar que Coverage Source es 'auto' en nodos GDD afectados"
  • paso7: "Asegurar cobertura >= 85% y 0 tests fallando"
  • paso8: "Generar reporte en docs/test-evidence/issue-{id}/summary.md con resultados" output: |
  • Tests generados en tests/unit/, tests/integration/, tests/e2e/
  • Reporte de cobertura: coverage/coverage-summary.json
  • Evidencias visuales: docs/test-evidence/issue-{id}/screenshots/
  • Resumen: docs/test-evidence/issue-{id}/summary.md examples:
  • contexto: "Se añadió un nuevo endpoint POST /api/roastr/persona" accion: "Generar tests para validar creación, actualización y borrado de persona" output_esperado: "tests/unit/routes/roastr-persona.test.js + tests/integration/persona-flow.test.js"
  • contexto: "Se creó nuevo componente UserProfile.jsx" accion: "Generar tests unitarios + E2E visual con Playwright" output_esperado: "tests/unit/components/UserProfile.test.jsx + tests/e2e/profile-page.test.js + screenshots" rules:
  • NUNCA usar datos reales (siempre mock data)
  • Seguir patrones de tests existentes en tests/
  • Cada archivo de producción debe tener su contraparte de test
  • Tests deben ser aislados, reproducibles y auto-contenidos
  • Usar nomenclatura descriptiva (test describe el comportamiento esperado) references:
  • "docs/TESTING.md - Guía completa de testing"
  • "docs/GDD-PHASE-15.1.md - Coverage authenticity"
  • "CLAUDE.md - Commit sin tests prohibido"
