Research in Refactoring Tools

Refactoring

Refactoring is the process of modifying existing source codebase in a structured and incremental way while preserving its external behavior. This process preserves the functionality of the program without introducing new bugs. Refactoring also promotes reuse of the existing codebase for other purposes thus increasing code reusability.

Fundamentals

Refactoring is primarily focused on the definitions and mechanism of refactoring, and proving their correctness. Refactoring means that the behaviour/functionality of the program does not change and therefore any program which meets its specifications before refactoring will continue to meet those specifications even afterwards. Refactoring can be done on any codebase and it is a general set of operations. Hence it comes witha precondition which specify under what circumstances refactoring can be done, alos with demonstrations that the dependency graphs are unchanged even after the refactoring is performed.
