Overview:

In modern software development, regression tests are used to confirm the fundamental functionalities of an edited program and to assure the code quality. Difficulties occur when testing reveals unexpected behaviors, which indicate potential defects introduced by the edit. However, the changes that caused the failure(s) are not always easy to find. The paper proposes a heuristic that ranks method changes that might have a effected a failed test, indicating the likelihood that they may have contributed to a test failure. The heuristic is based on the calling structure of the failed test (e.g., the number of ancestors and descendents of a method in the test's call graph, whether the caller or callee was changed, etc.).
