Abstract: Introducing scenario of use case to object-oriented software testing is very helpful for the design of test suit. This paper applies the advantages of intuition and better coupling characteristic provided by CPNs model to description of UML scenario, and presents an integration algorism for CPNs scenario model, chameleon tokens of which is used to capture not only the scenarios in UML specification but also the further added to it. The paper discusses how to generate test cases according to the CPNs scenario integration model as the result of the algorism.

Key words: Scenario of use case, Test cases generation, Colored Petri nets(CPNs), Scenario integration, Chameleon tokens

摘要： 将用例场景引入面向对象的软件测试中，有利于测试设计者设计测试用例。将着色Petri网(Colored Petri Nets，CPNs)模型直观可靠的特点和较好的耦合性运用到UML用例场景的描述中，进一步给出了CPNs场景模型的集成算法，并运用变色标记捕获UML规约中的场景及更多新增的场景。同时探讨了基于CPNs场景模型的测试用例生成方法。
