Methodology: Agile Software Development: Refactoring
Methodology: Agile Software Development: Refactoring

Learn how to work effectively with legacy code in three steps. First, add pin-down tests that help usunderstand the legacy behavior. In addition, these tests "pin down" the legacy code—they hold it in place so we can refactor it without accidentally changing its behavior. Next, we refactor to simplify the code. Finally, we add the new feature to the refactored code.
