Abstract: This paper presents a novel regression test method to test object oriented software based on UML design. It obtains classes and methods which must be retested after software’s modification, and analyzes UML sequence diagrams with respect to these classes, then identifies the message guards on sequence diagrams and creates dynamic slices about each conditional predicates, and generates test data for this slice.

Key words: regression test, UML sequence diagram, slice coverage, test case generation

摘要： 针对基于UML设计的面向对象软件在修改后进行回归测试的情况，提出一种回归测试用例生成的新方法。获取软件修改后进行回归测试时必须重新测试的类和方法，分析与需要重测试类有关的UML顺序图，对顺序图中每个包含不等关系的条件断言生成与其有关的动态程序切片，根据该动态程序切片生成与其相应的回归测试用例。
