To refactor long methods and improve code readability, extract complex blocks into smaller, well-named functions. This restructuring simplifies future modifications and reduces maintenance risks without altering external behavior.

The best way to restructure code without changing functionality is to systematically address code smells like duplicate code and feature envy. Techniques like Rename and Remove Dead Code improve maintainability while preserving the original logic.

Yes, you need passing tests to safely improve code maintainability during refactoring. Maintaining passing tests throughout the restructuring process ensures code integrity and verifies that external behavior remains unchanged.

Removing dead code and duplicate code boosts software testability by eliminating redundant execution paths and simplifying the structure. This makes unit tests easier to create and execute while addressing common code smells.

Yes, you can fix feature envy by extracting methods during the refactoring process. Restructuring the misplaced code into appropriate classes or functions improves overall code quality and maintainability without breaking existing functionality.
