+- **Test coverage**: Asset loading (images, videos, logos), navigation flows, smooth scroll animations
+- **Environment testing**: Tests verify functionality in both localhost and GitHub Pages simulation  
+- **404 detection**: Tests specifically check for and report any 404 errors for assets or navigation
+- **Navigation flows tested**:
+  - Casos de éxito (with smooth scroll animation verification)
+  - Home navigation
+  - Academia page navigation
+  - Carreras page navigation
+  - Qué hacemos section scroll
+  - Novit logo click (return to home)
+- **Asset verification**: Case study images, Novit official logos, hero-academia.mp4 video
+- **Cross-locale testing**: Tests run in Spanish, English, and Portuguese locales
 
 ### Manual Validation Requirements
 - **CRITICAL**: After any changes, always test the complete user journey: homepage load → language switching → navigation → key interactions

+# Docker Testing Implementation Summary
+
+## ✅ What Was Implemented
+
+### 🐳 Docker Infrastructure
+- **Dockerfile.playwright**: Linux testing environment with Playwright pre-installed
+- **docker-compose.yml**: Production testing configuration
+- **docker-compose.dev.yml**: Development testing configuration
+- **.dockerignore**: Optimized Docker builds
+
+### 📦 NPM Scripts Added
+- `test:docker` - Run all tests in Docker container
+- `test:docker:dev` - Interactive development mode
+- `test:docker:clean` - Clean Docker environment
+- `test:docker:validate` - Validate Docker configuration
+- `docker:build` - Build Docker image
+- `docker:setup` - Verify Docker installation
+
+### 📖 Documentation
+- **DOCKER_TESTING.md**: Comprehensive Docker testing guide
+- **README.md**: Updated with Docker testing instructions
+- **Validation script**: Automated Docker setup verification
+
+## 🎯 Problem Solved
+
+### ❌ Before (Issue)
+- Tests only worked on Linux/macOS
+- Windows users couldn't run Playwright tests locally
+- Inconsistent environments between local and CI/CD
+- Development blocked on Windows machines
+
+### ✅ After (Solution)
+- **Cross-platform**: Works identically on Windows, macOS, Linux
+- **Consistent**: Same Linux environment everywhere
+- **Isolated**: Doesn't interfere with local installations
+- **CI/CD Parity**: Exactly matches GitHub Actions environment
+
+## 🚀 How to Use
+
+### First Time Setup
+```bash
+# 1. Verify Docker is working
+npm run docker:setup
+
+# 2. Validate all configuration
+npm run test:docker:validate
+
+# 3. Run all tests
+npm run test:docker
+```
+
+### Development Workflow
+```bash
+# Interactive testing with live code changes
+npm run test:docker:dev
+
+# Clean environment when needed
+npm run test:docker:clean
+```
+
+## 🔧 Technical Details
+
+### Dual Environment Testing
+- **localhost:3000**: Next.js development server
+- **localhost:8000**: Static build (GitHub Pages simulation)
+
+### Docker Volumes
+- Source code mounted for live development
+- Test results preserved outside container
+- Node modules isolated for platform compatibility
+
+### Environment Variables
+- `CI=true` for production-like testing
+- `NODE_ENV=development` for development mode
+- `DEPLOY_TARGET=github-pages` for static builds
+
+## 🎉 Benefits
+
+1. **Windows Compatibility**: No more Playwright installation issues on Windows
+2. **Consistency**: Identical results across all platforms
+3. **CI/CD Parity**: Local testing matches GitHub Actions exactly
+4. **Isolation**: Clean environment that doesn't affect local setup
+5. **Easy Collaboration**: All team members can run tests regardless of OS
+
+## 📝 Files Created/Modified
+
+### New Files
+- `Dockerfile.playwright`
+- `docker-compose.yml`
+- `docker-compose.dev.yml`
+- `DOCKER_TESTING.md`
+- `scripts/validate-docker.sh`
+
+### Modified Files
+- `package.json` (added Docker scripts)
+- `README.md` (added Docker testing section)
+- `.gitignore` (added Docker exclusions)
+
+This implementation fully addresses the user's request for cross-platform testing capability while maintaining the existing dual-environment testing architecture.

+# Docker Testing Guide
+
+Este documento explica cómo usar Docker para ejecutar las pruebas de Playwright en cualquier plataforma (Windows, macOS, Linux).
+
+## ¿Por qué Docker?
+
+- **Consistencia**: El mismo entorno Linux en todas las plataformas
+- **GitHub Actions**: Replica exactamente el entorno de CI/CD
+- **Windows**: Soluciona problemas de compatibilidad de Playwright en Windows
+- **Aislamiento**: No interfiere con tu instalación local de Node.js
+
+## Prerrequisitos
+
+1. **Docker Desktop** instalado y ejecutándose
+   - Windows: [Docker Desktop for Windows](https://docs.docker.com/desktop/windows/install/)
+   - macOS: [Docker Desktop for Mac](https://docs.docker.com/desktop/mac/install/)
+   - Linux: [Docker Engine](https://docs.docker.com/engine/install/)
+
+2. **Docker Compose** (incluido con Docker Desktop)
+
+## Comandos Principales
+
+### 🧪 Ejecutar Todas las Pruebas
+```bash
+npm run test:docker
+```
+- Construye el contenedor
+- Ejecuta todas las pruebas (dev + static)
+- Se cierra automáticamente al finalizar
+
+### 🔧 Desarrollo Interactivo
+```bash
+npm run test:docker:dev
+```
+- Modo interactivo para desarrollo
+- Los cambios en el código se reflejan en tiempo real
+- Ideal para depurar pruebas
+
+### 🧹 Limpiar Entorno
+```bash
+npm run test:docker:clean
+```
+- Elimina contenedores y volúmenes
+- Útil para empezar desde cero
+
+### 🐳 Verificar Docker
+```bash
+npm run docker:setup
+```
+- Verifica que Docker esté funcionando
+- Muestra versiones de Docker y Docker Compose
+
+### ✅ Validar Configuración
+```bash
+npm run test:docker:validate
+```
+- Valida toda la configuración Docker
+- Verifica sintaxis de archivos
+- Confirma que todo está listo para usar
+
+## Arquitectura de Pruebas
+
+### Entornos Duales
+1. **localhost:3000** - Servidor de desarrollo Next.js
+2. **localhost:8000** - Build estático (simula GitHub Pages)
+
+### Tipos de Pruebas
+- `assets.dev.spec.ts` - Pruebas específicas de desarrollo
+- `assets.static.spec.ts` - Pruebas de GitHub Pages con base path `/web-novit`
+- `navigation.shared.spec.ts` - Pruebas que corren en ambos entornos
+
+## Estructura de Archivos Docker
+
+```
+├── Dockerfile.playwright     # Imagen base para pruebas
+├── docker-compose.yml        # Configuración de producción
+├── docker-compose.dev.yml    # Configuración de desarrollo
+└── DOCKER_TESTING.md        # Esta documentación
+```
+
+## Solución de Problemas
+
+### Error: "Docker no está ejecutándose"
+```bash
+# Verifica que Docker Desktop esté iniciado
+docker --version
+docker-compose --version
+```
+
+### Error: "Puerto ya en uso"
+```bash
+# Detén otros servidores locales
+npm run test:docker:clean
+```
+
+### Error: "Permisos en Linux"
+```bash
+# Añade tu usuario al grupo docker
+sudo usermod -aG docker $USER
+# Reinicia la sesión
+```
+
+### Rendimiento Lento en Windows
+- Asegúrate de que el proyecto esté en el sistema de archivos Linux en WSL2
+- Habilita WSL2 backend en Docker Desktop
+
+## Comparación: Local vs Docker
+
+| Aspecto | Local | Docker |
+|---------|-------|--------|
+| **Windows** | ❌ Problemas con Playwright | ✅ Funciona perfectamente |
+| **Consistencia** | ⚠️ Depende del SO | ✅ Idéntico en todas partes |
+| **CI/CD** | ⚠️ Posibles diferencias | ✅ Exactamente igual |
+| **Velocidad** | ✅ Más rápido | ⚠️ Overhead de Docker |
+| **Configuración** | ⚠️ Dependencias locales | ✅ Todo incluido |
+
+## Integración con GitHub Actions
+
+Las pruebas en GitHub Actions usan el mismo entorno Docker, garantizando:
+- Mismos resultados en local y CI/CD
+- Detección temprana de problemas
+- Consistencia entre desarrolladores
+
+## Comandos Avanzados
+
+### Solo Build de Docker
+```bash
+npm run docker:build
+```
+
+### Ejecutar Comando Personalizado
+```bash
+docker-compose run playwright-tests npm run test:ui
+```
+
+### Ver Logs Detallados
+```bash
+docker-compose up --build
+```
+
+### Acceder al Contenedor
+```bash
+docker-compose run playwright-tests bash
+```
+
+## Próximos Pasos
+
+1. Ejecuta `npm run docker:setup` para verificar tu instalación
+2. Prueba `npm run test:docker` para ejecutar todas las pruebas
+3. Usa `npm run test:docker:dev` para desarrollo interactivo
+
+¡Con Docker, las pruebas funcionan idénticamente en Windows, macOS y Linux! 🐳✨
