摘　　要：测试用例集优化技术是软件测试的重要组成部分,对回归测试检测效率影响巨大。针对给定的测试目标,获得精简的测试需求集和测试用例序列集,有助于提高测试用例集优化的效率和效果。首先介绍了测试用例集约简问题的基本概念,对现有的各种约简方法进行分析比较,接着讨论了测试用例的优先级排序问题,最后提出将测试用例约简技术和优先级技术结合起来,提高用例检错效率和缩小用例空间的优化策略,文章还引入等价类和快速排序思想,动态调整测试用例序列,并通过实验证明该改进是行之有效的。Test Suite optimization is an important component of software testing,and especially has a significant impact on the efficiency of regression testing. For given test objectives obtaining a simple test requirement set and test sequence set are helpful to improve the efficiency. Some concepts of test suite＇s reduction are introduced, analysis and comparison on current reduction methods are also given. Then the priority scheduling problem of test suite is discussed. Finally, this paper proposes a new st~＇ategy to improve the test efficiency and test suite size by combining reduction technology and priority technology. This paper also introduces ＇equivalence partitioning and quick sorting to change the test suites sequence dynamically. It proves that the improvement works in real testing.
