基于UML图和动态切片的回归测试研究

摘要

重点将UML图和动态切片应用于回归测试中.针对现在应用于软件开发的UML图不能很好地满足软件测试的要求,引入了时序状态图和改进后的状态图,对两种图进行形式化定义,并且通过实例说明定义内容,其中时序状态图用于类间测试,改进后的状态图用于类内测试.对定义的图进行切片分析,形成测试步骤和测试算法.网上购物实例表明时序状态图和改进状态图可以提高回归测试效率.%The focus of this paper is to apply die UML diagram and dynamis slice to regression testing. First, in view of the fact that the application of UML diagram in software development cannot well meet the requirements of the software testing, sequence-state diagram and improved state diagram are introduced, and then, two diagrams are defined, and the content is shown through examples, sequence-state diagram for between-class test, improved state diagram for in-class test. Then, defined diagrams are analyzed, and the steps of the test and test algorithm are formed. Finally, online shopping examples show that sequence-state diagram and improved state can increase the efficiency of regression testing.
