What is the process of refactoring in automation testing?

Refactoring in automation testing is primarily focused on modifying existing test code to improve its structure, readability, or performance without altering its external behavior. This process enhances the maintainability of the code, making it easier to understand and work with over time. By simplifying complex test scripts, eliminating redundancy, and adopting better practices, refactoring allows testers to ensure that their automation frameworks remain efficient and manageable as the application or system under test evolves.

While rewriting test scripts completely might seem beneficial in some circumstances, it can introduce new errors and may not focus on improving the existing structure. Increasing the number of test cases may add to the robustness of the testing suite, but it does not directly relate to improving code quality. Validating test outcomes is an essential aspect of testing, but it does not encompass the concept of refactoring, which is concerned with code quality and design rather than testing results.
