1. 🚀 QUICK START TEST:
   - Run: python main.py
   - Visit: http://localhost:8000/docs
   - Test API endpoints in the interactive documentation

2. 🧪 INTEGRATION TEST:
   - Run: python test_app.py
   - This creates a sample application using the framework
   - Demonstrates how to integrate into your own project

3. 📚 USAGE EXAMPLES:
   - Check run_example.py for integration patterns
   - Review README.md for detailed usage instructions

4. 🔧 CUSTOM TESTING:
   - Create your own FastAPI app
   - Initialize AdaptiveAuth with your settings
   - Mount the router and test endpoints

5. 🧪 UNIT TESTING:
   - Run this script: python test_framework.py
   - Validates core framework functionality
   - Ensures all components work together

The framework is designed to be:
✅ Easy to install (pip install -r requirements.txt)
✅ Simple to integrate (few lines of code)
✅ Comprehensive in features (auth, 2FA, risk assessment)
✅ Well-documented (clear README and examples)
✅ Developer-friendly (easy-to-use APIs)
