To refactor a long method for better code readability, you can apply the Extract Method technique to break down complex functions into smaller, manageable methods. This systematically addresses code smells while preserving original behavior through incremental application.

Common code smells include long methods, large classes, duplicate code, and complex conditionals. Identifying these structural issues involves systematically analyzing your codebase to pinpoint areas where simplification and generalization refactorings can enhance overall software quality.

The best way to remove duplicate code while ensuring behavior preservation is to extract the duplicated logic into a separate method. This structural refactoring improves maintainability and is verified incrementally through tests to ensure no regressions occur.

Yes, you can simplify complex conditionals without changing functionality by applying the Decompose Conditional refactoring. This technique breaks intricate conditional logic into clearer clauses, enhancing readability while strictly preserving the software's behavior.

You need to use the Introduce Parameter Object refactoring when a method receives multiple parameters that logically belong together. This structural refactoring groups them into a single object, simplifying method signatures and improving long-term code maintainability.

Yes, existing tests are essential to safely apply clean code refactorings. The process relies on behavior preservation through tests and incremental application, ensuring that structural changes like extracting methods do not introduce bugs or alter functionality.
