## 🧪 Testing

### Test API Health
```bash
curl http://localhost:5000/api/health
```

### Test Summarization
```bash
curl -X POST http://localhost:5000/api/summarize \
  -H "Content-Type: application/json" \
  -d '{"text": "نص تجريبي للاختبار", "length": 2, "full_text": true}'
```

## 🐛 Troubleshooting

### Model Not Found
- Verify model path: `models/arabic_summarization_model/content/drive/MyDrive/arabic_summarization_model/`
- Check that `config.json` exists
- The app will search multiple possible locations automatically

### Dependencies Missing
```bash
python check_dependencies.py
pip install -r requirements.txt
```

### Port Already in Use
```bash
set PORT=5001
python run_app.py
```
