摘要： 对构件软件测试的特点进行了分析，结合扩展的UML 状态图规约和时序图规约，以文献[1]4 个能模拟构件间交互特性的要素作为测试用例产生的基础，特别是分析了构件间的内容依赖关系和上下文依赖关系获取算法，从而提出一种有效地构件软件集成测试用例的生成方法。

Abstract: This paper with UML extension which are statechart diagram and sequence diagram for CBSE analyses the features of component based software testing and founds generating test case on four elements in the literature[1] that can model the characteristics of the interactions between components, especially, to impose arithmetic of gaining context-dependence relationships and content-dependence relationships. And according to these elements, this paper proposes a valid method of generating test case for component based software Integration testing
