refactor

Safely refactor code by applying test-driven development principles to ensure behavioral integrity. The process executes tests before and after each incremental change, verifying that no functionality is broken and that test coverage is maintained or improved.

Code smells are indicators of poor design and maintainability issues like overly complex logic or unclear identifiers. You should refactor when functions become too long and complex, extracting parts into smaller, more manageable functions to improve readability and testability.

Extract functions and simplify complex conditional logic by applying common refactoring patterns. This automated process breaks down large functions into smaller components and clarifies conditional statements, improving overall code readability and maintainability.

Existing tests are required to ensure refactoring is always backed by test-driven safety. If necessary, the process creates new tests to verify behavior before and after applying incremental code changes.

Improve code maintainability by renaming identifiers for improved clarity through automated refactoring. This approach addresses code smells and simplifies logic while executing tests before and after changes to ensure no functionality is broken.

Refactoring without sufficient test coverage risks breaking behavioral integrity because tests verify functionality before and after changes. The process creates new tests if necessary to ensure complex logic remains intact during incremental modifications.
