Abstract

Testing and code editing are interleaved activities during program development. When tests fail unexpectedly, the changes that caused the failure(s) are not always easy to find. We explore how change classification can focus programmer attention on failure-inducing changes by automatically labeling changes Red, Yellow, or Green, indicating the likelihood that they have contributed to a test failure. We implemented our change classification tool JUnit/CIA as an extension to the JUnit component within Eclipse, and evaluated its effectiveness in two case studies. Our results indicate that change classification is an effective technique for finding failure-inducing changes.
