Abstract: Test case prioritization(TCP),which can effectively improve the testing efficiency and reduce testing time overhead and labor costs in iterative software development process,has attracted widespread attention of researchers.And many optimization methods have been proposed.But most methods incline to TCP technology based on requirement and coverage,and keep a static sort.This paper presented a TCP technology based on history information,and we dynamically adjusted the prioritization of test cases during the execution of test cases.This method helps to find defects as early as possible and to achieve the goal of bug detection.Finally,we applied our method to the project developed by our research group to verify the effectiveness of our method.
