Refactor test cases and base code for consistency and readability

- Updated byte representations in tests to use lowercase hex format for consistency.
- Reformatted code for better readability, including line breaks and indentation adjustments.
- Consolidated multiple lines into single lines where appropriate to enhance clarity.
- Ensured that all test cases maintain consistent formatting and style across the test suite.
