Testing

Run Tests

python test_runner.py                    # Run all tests
python test_runner.py -v                 # Verbose mode with detailed validation status
python test_runner.py -vv                # More verbose with validation check failure reason

python test_runner.py -f vectors.json    # Use custom test vector file

Generating Test Vectors
