摘要： 将UML状态图、程序切片和软件测试技术三者结合起来，生成基于依赖性分析的UML状态图切片，为软件测试中待测试的程序的理解、发现和修改错误提供了一种方法。最后运用实例讨论了该切片方法的实用性，应用于回归测试中具有较高的效率。

Abstract: This paper combines the three techniques UML statechart diagram, program slicing and software testing together to generate the UML statechart slices that based on the dependency analysis. It provides a method for the program comprehension, errors finding and modification during the process of sofrware testing. At last the case study is given to show the applicability and higher effiency of the slicing method used in the regression test.

Key words: UML, UML statechart diagram, Slice, Dependency analysis
