| Outline of Final Research Achievements |
In this research study, we showed that a spatial frame defined as a set of test cases is capable of relaxing the definition of the behavior preservation in refactoring. Additionally, we proposed a mechanism that automatically generates new complementary test cases that are likely to help a programmer define spatial frames. A temporal frame separates the time period in which the behavior preservation should be guaranteed from the whole process of automated refactoring. To increase the applicability of automated refactoring, a postponable refactoring tool employing temporal frames allows a programmer to suspend the execution of the applied refactoring if its preconditions are not satisfied and to restart the suspended refactoring once all the preconditions are satisfied. We also developed a platform that can record accurate and intelligible textual changes of source code evolution, especially including code changes by refactoring.
