Refactor tests for improved clarity and consistency

- Removed unnecessary imports and added newlines for better formatting in test_discovery.py.
- Updated test names in test_gui.py for clarity and added a dummy test for GUI launch.
- Ensured consistent formatting by adding newlines at the end of files where necessary.
