PROBLEMAS ENCONTRADOS Y RESOLUCIONES

1. Jest vs Vitest Syntax

Problema: Tests escritos con sintaxis Jest pero proyecto usa Vitest Resolución: Migración global jest. → vi. en todos los archivos

2. HTMLVideoElement.duration Property

Problema: No se puede redefinir duration (property already defined) Resolución: Definir una sola vez en setup.ts global, remover de tests individuales

3. Node Modules Missing

Problema: node_modules no instalado en frontend Resolución: npm install antes de ejecutar tests

4. Componente VideoUploadForm No Encontrado

Problema: Tests de componente fallan porque buscan selectores específicos Resolución: Tests quedan escritos, requieren ajuste según implementación real del componente

PRÓXIMOS PASOS

Ejecución Completa

# Frontend
cd apps/frontend
npm run test video-upload --run
npm run test -- --coverage

# Backend
cd apps/backend
npm run test video
npm run test -- --coverage

Validación Coverage

• Ejecutar con coverage reporter
• Verificar > 80% en módulos críticos
• Documentar gaps si existen

Ajustes Post-Implementación

• Ajustar selectores en tests de componentes según implementación real
• Agregar tests adicionales si coverage < 80%
• Optimizar tests lentos si necesario

---

LECCIONES APRENDIDAS

Positivo

✅ Tests escritos antes permiten desarrollo TDD si componente cambia ✅ Estructura modular (7 suites) facilita mantenimiento ✅ Mocks estratégicos permiten tests rápidos y aislados ✅ Migración Jest→Vitest fue directa con find/replace

Mejoras Futuras

⚠️ Considerar tests E2E con Playwright para validación browser real ⚠️ Agregar tests de performance (tiempo de upload, memory leaks) ⚠️ Considerar tests con archivos reales pequeños (no solo mocks)
