- Created test_all_demos.py for quick demo execution testing
- Added validate_demos.py for detailed output validation
- Both scripts use Rich CLI for clear test reporting
- All 8 demos passing with 100% success rate
- 48 detailed validation checks all passing
- Scripts check for:
- Demo execution without errors
- Expected outputs and patterns
- Educational content presence
- Proper completion messages
- Specific functionality for each demo
This ensures demo reliability for students and makes it easy to
catch regressions when updating the codebase.
