Refactor test files to remove unused imports and improve readability

- Removed unnecessary imports from various test files, including pytest and unused classes.
- Simplified assertions and variable names for clarity.
- Updated import statements for consistency across test files.
- Enhanced code structure by removing commented-out code and redundant lines.
- Improved the organization of imports in several widget files for better maintainability.
