# Script de Prueba: Integración MissionsService en ExerciseAttemptService
#
# Propósito: Validar que las misiones se actualizan correctamente al completar ejercicios
#
# Flujo de prueba:
# 1. Crear una misión diaria con objetivo 'complete_exercises'
# 2. Completar un ejercicio correctamente
# 3. Verificar que la misión se actualizó
#
# Uso: bash scripts/test-missions-integration.sh
