Which of the following activities is NOT typically included in the process of refactoring?

Refactoring primarily focuses on improving the internal structure of code without altering its external behavior. This is aimed at enhancing readability, maintainability, and performance of the codebase.

Automatically generating test cases is not a typical activity involved in refactoring. Instead, refactoring usually assumes that there are existing tests that confirm the behavior of the system. The goal of refactoring is to improve the code while keeping the existing functionality intact, and thus, it generally involves activities like extracting methods for better readability, removing unnecessary comments, and clarifying the meaning of complex parts of the code, including the management of magic numbers. However, the generation of new test cases to validate changes made during refactoring is an additional step and not inherently a part of the refactoring process itself. The focus during refactoring remains on restructuring rather than creating new testing artifacts.
