+# Testing Workflow - PyTest que Replica SAM CLI Manual
+
+## 🚀 Setup y Ejecución (Workflow Limpio)
+
+### **Prerequisitos**
+- Docker running
+- AWS SAM CLI instalado
+- Python 3.10+
+
+### **1. Preparar el Entorno**
+
+```bash
+# Navegar al directorio del proyecto
+cd dynamodb-crud-lambda-local
+
+# Build SAM application
+cd tests
+sam build
+
+# Verificar build exitoso
+ls .aws-sam/build/  # Debería mostrar las 5 funciones Lambda
+```
+
+### **2. Iniciar DynamoDB Local (FUERA de PyTest)**
+
+```bash
+# Iniciar DynamoDB Local con network host
+docker run --rm -d --name dynamodb-local --network host amazon/dynamodb-local
+
+# Verificar que esté corriendo
+curl http://localhost:8000/  # Debería responder
+```
+
+### **3. Configurar Variables de Entorno**
+
+```bash
+# En el directorio tests/
+export AWS_ACCESS_KEY_ID='DUMMYIDEXAMPLE'
+export AWS_SECRET_ACCESS_KEY='DUMMYEXAMPLEKEY'
+export AWS_REGION='us-east-1'
+```
+
+### **4. Setup Python Environment**
+
+```bash
+# Crear y activar virtual environment
+python3 -m venv venv
+source venv/bin/activate
+
+# Instalar dependencias
+pip install --upgrade pip
+pip install -r requirements.txt
+```
+
+### **5. Ejecutar Tests**
+
+```bash
+# Ejecutar todos los tests
+python3 -m pytest -s unit/src/test_lambda_dynamodb_local.py
+
+# Ejecutar test específico
+python3 -m pytest -s unit/src/test_lambda_dynamodb_local.py::test_lambda_create_function
+
+# Ejecutar con verbose output
+python3 -m pytest -s -v unit/src/test_lambda_dynamodb_local.py
+```
+
+### **6. Cleanup**
+
+```bash
+# Limpiar Python environment
+deactivate
+rm -rf venv/
+
+# Limpiar variables
+unset AWS_ACCESS_KEY_ID
+unset AWS_SECRET_ACCESS_KEY
+unset AWS_REGION
+
+# Parar DynamoDB container
+docker stop dynamodb-local
+```
+
+## 📊 Output Esperado (Limpio)
+
+```

+
+## 🛠️ Troubleshooting
+
+### **Si DynamoDB no está disponible:**
+```
+SKIPPED [1] DynamoDB Local is not running on port 8000. Please start with 'docker run --rm -d --name dynamodb-local --network host amazon/dynamodb-local'
+```
+**Solución:** Ejecutar el comando Docker mostrado.
+
+### **Si SAM build no está actualizado:**
+```
+Lambda import error: No module named 'app'. Please ensure 'sam build' has been run successfully.
+```
+**Solución:** 
+```bash
+cd tests
+sam build
+```
+
+### **Si hay conflictos de puertos:**
+```bash
+# Verificar qué está usando el puerto 8000
+sudo netstat -tlnp | grep :8000
+
+# Matar procesos si es necesario
+docker stop dynamodb-local
+```
+
+### **Si hay problemas de networking:**
+- Verificar que Docker esté corriendo: `docker version`
+- Verificar que `--network host` esté disponible (Linux/macOS)
+- En Windows, puede necesitar configuración especial
+
+## 🔄 Re-ejecución de Tests
+
+Los tests ahora son **completamente idempotentes**:
+
+```bash
+# Puedes ejecutar múltiples veces sin problemas
+python3 -m pytest -s unit/src/test_lambda_dynamodb_local.py
+python3 -m pytest -s unit/src/test_lambda_dynamodb_local.py  # ✅ Funciona
+python3 -m pytest -s unit/src/test_lambda_dynamodb_local.py  # ✅ Funciona
+```
+
+## 📝 Diferencias vs. Versión Anterior
+
+| Aspecto | Versión Anterior | Nueva Versión |
+|---------|------------------|---------------|
+| **DynamoDB Management** | PyTest maneja container | Container externo |
+| **Networking** | Sin `--docker-network host` | Con `--docker-network host` |
+| **Clean State** | No cleanup automático | Cleanup automático al inicio |
+| **Error Handling** | Muestra todos los errores | Filtra warnings harmless |
+| **Idempotency** | No idempotente | Completamente idempotente |
+| **Output** | Confuso con errores | Limpio y claro |
+
+## 🎯 Validación Manual
+
+Para verificar que PyTest replica exactamente el comportamiento manual:
+
+```bash
+# Test manual (debería funcionar igual que PyTest)
+docker run --rm -d --name dynamodb-local --network host amazon/dynamodb-local
+
+sam local invoke CRUDLambdaInitFunction --docker-network host --event ../events/lambda-init-event.json
+sam local invoke CRUDLambdaCreateFunction --docker-network host --event ../events/lambda-create-event.json
+sam local invoke CRUDLambdaReadFunction --docker-network host --event ../events/lambda-read-event.json
+sam local invoke CRUDLambdaUpdateFunction --docker-network host --event ../events/lambda-update-event.json
+sam local invoke CRUDLambdaDeleteFunction --docker-network host --event ../events/lambda-delete-event.json
+
+# Cleanup
+docker stop dynamodb-local
+```
+
+Ambos (manual y PyTest) deberían dar **exactamente los mismos resultados**.
