Fix code smells by applying small, safe structural changes like Extract Method and Extract Class. This preserves behavior by maintaining functional equivalence and passing tests while documenting the reasoning behind each modification.

Simplify complex conditionals by applying the Replace Conditional with Polymorphism pattern. This refactoring technique improves code structure and readability while maintaining functional equivalence and ensuring tests still pass.

Identify code smells by analyzing production code for long methods, large classes, and complex conditionals. Recognizing these structural issues determines the appropriate refactoring patterns needed to safely improve the codebase.

Yes, you can apply design patterns like Replace Conditional with Polymorphism to clean up complex conditionals across typical software project modules. This approach applies structural improvements while maintaining functional equivalence and passing tests.

Yes, passing tests are a required constraint when applying refactoring techniques like Extract Class. Maintaining functional equivalence and test preservation ensures structural changes improve code quality without altering external behavior.
