Test code differencing for test-driven refactoring automation

Abstract

Test-driven refactoring (TDR) requires the developer to finish test adaptation before applying refactoring. However, the current approaches of TDR usually compromise the principle of Test-First and make the refactoring intent implicit. The failed delivery of refactoring intent hinders the opportunity of test-driven refactoring automation (TDRA). In this paper, a test code differencing algorithm TestDiff is provided to extract refactoring intents from test adaptation. A tool, Refiner, is demonstrated and evaluated by real cases.
