To refactor long methods safely, you apply behavior-preserving transformations like Extract Method, breaking large logic into smaller intention-revealing methods while relying on a test-first workflow to verify identical output.

Simplifying complex conditional logic involves applying named transformations like conditional simplification to deconstruct intricate structures into clearer designs, guided by mapping specific code smells to their corresponding mechanical refactorings.

The best way to map code smells to refactorings is to identify the primary issue—such as Feature Envy or Duplicate Code—and select the smallest mechanical transformation that addresses it, followed by test verification.

Yes, a test-backed workflow is required. You must run tests before and after each small incremental refactoring step to ensure the changes remain behavior-preserving and avoid introducing technical debt.

Improving object responsibilities involves restructuring code to replace primitive data representations and organizing domain data using named transformations, ensuring each object handles its own logic safely.
