摘　　要：UML 顺序图是基于 UML 开发的软件设计模型的重要组成部分,它描述了软件系统的动态行为,是软件集成测试过程中的一个重要的信息来源。本文提出了一个基于 UML 顺序图的场景测试方法,它以 UML 顺序图为主要测试模型,结合 UML 状态图和类图生成所有的测试场景,最后使用范畴-划分方法找到与每一场景相关的环境条件并将它与方法序列、输入、输出合理组合作为覆盖该场景的测试用例,用于测试该场景中对象之间的交互。由于 UML已广泛用于软件分析和设计阶段,通过 UML 模型生成测试用例可充分利用已有的设计结果,减少测试阶段所需的费用,对于已使用 UML 的工业界有着重要的意义。UML sequence diagram is an important component of software design model based on UML. Because it de- scribes the dynamic behaviors of a software system, it becomes a valuable information source in software integration test. This paper proposes an approach to generate scenario test cases based on UML sequence diagrams. It takes UML sequence diagrams as its main test model and generates all test scenarios combining UML state diagrams and class diagrams, then it applies category partition method to find environmental settings related to each scenario and combines them with method call sequence ,as well as input and output, to form a test case for each scenario, thus we can test the interactive behavior of the software. Because UML has been widely used in software analysis and design phrases, using UML to generate test cases can make the most of the existing design results and reduce the expenses of test phrase. Accordingly, it is significant to industry in which UML has been used.
