Refactor test cases for improved readability and consistency

- Adjusted function signatures in various test files to enhance clarity by aligning parameters.
- Updated patching syntax for better readability across test cases.
- Improved formatting and spacing in test assertions and mock setups.
- Ensured consistent use of async/await patterns in async test functions.
- Enhanced comments for better understanding of test intentions.
