Towards refactoring-aware code review.

ABSTRACT Software developers review changes to a code base to prevent new bugs from being introduced. However, some parts of a change are more likely to introduce bugs than others, and thus deserve more care in reviewing. In this short paper, we discuss our ongoing work to build a reviewing tool that automatically determines which changes in a change set are refactorings, uses this information to help the developer distinguish between refactoring and non-refactoring changes, and ultimately reduces the time it takes developers to review code accurately. We also discuss the challenges and opportunities we have faced when building this refactoring-aware code review tool.
