- Removed class-based test structure - Moved imports to top of file - Added section dividers (============) between test groups - Removed inline imports - Followed same structure as test_serving_chat_sampling_params.py - All tests are now standalone functions with proper docstrings This aligns with the test style guide at docs/contributing/ci/tests_style.md Co-authored-by: hsliuustc0106 <222337142+hsliuustc0106@users.noreply.github.com>
