What are the main reasons to apply code refactoring?
The following motivations are among the most common: • To make it easier to modify and add new code. The grouping and separation of common pieces of code allows for centralization of functionality. If functionality needs to be changed, it can be done in one single place. • To improve the design of existing code. Refactoring tends to produce clearer code and eases the adoption of enterprise development standards. It also allows the developer to easily develop and test different system models and designs to identify which one best fits the enterprise needs. • To gain a better understanding of code. The clarity and organization gain obtained with refactoring allows the human reader to identify and understand the key concepts of the functionality. • Improved growth and integration capabilities. The code can grow in an organized and systematic way; this allows for the definition of standard interfaces that ease integration and reusability.
