摘　　要：回归测试时,测试用例优先级排序是提高测试效率和测试有效性的主要技术。针对回归测试阶段如何选择和使用测试用例的问题,提出一种新的回归测试优先级排序技术,并设计新技术的实现算法。上述改进技术将与软件相关的错误检测率、错误等级和错误类型等因素应用于测试用例优先级排序。通过实验,比较上述技术排序后用例和未排序用例错误检测情况,结果表明,改进技术排序后的测试用例能够提高回归测试执行效率,有效保证软件质量。Test case prioritization is an effective and validity technique of regression testing. To solve the problem of how to choose and use test cases in regression testing, a test case prioritization technique and a prioritization algo- rithm were proposed in this paper. Three factors related to software fault were taken into account in the technique for ranking test cases. The factors are rate of fault detection, fault impact and fault type. In this paper, the average of percentage of detected faults was used as a measurement criterion. Compared the prioritized test case with the non prioritized one, the experimental results show that the efficiency of regression testing is improved and the better soft- ware quality is achieved by using this technique.
