Abstract: Refactoring provides systematic changes to program code in order to improve its quality. These changes could also require modifications of unit tests associated with a refactored program. Developer environments assist with many code refactoring transformations, which also support some modifications of the tests. Two popular environments for Java programs have been found to be unable to update these tests for all refactoring in a satisfactory way. The flaws in refactoring, the adaptation of the tests after refactoring, and possible improvements were discussed. A tool extension has been introduced to integrate with a refactoring in the Eclipse environment and maintain the corresponding tests. For selected refactorings, additional test cases could also be created to increase code coverage and improve the testing of a refactored program. Experiments have been conducted to evaluate the proposed solutions and verify their limitations.
