- 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.
