摘　　要：基于模型的测试用例生成方法已经被软件行业所接受。这种方法的优点在于可以及早地发现缺陷,减少软件开发的时间等等。现在,研究者已经考虑从UML图中获得测试用例。文中介绍了一种从UML2.0活动图中产生测试用例的方法。提出了活动路径覆盖准则,重点分析并发活动的顺序及排列,引入深度优先与广度优先结合的生成算法,避免了测试用例数量爆炸,提高了自动化生成测试用例的可行性,从而为UML活动动图的自动化测试提供了系统的、有效的、可行的方法。Model-based test case generation is gaining acceptance to the software practitioners.Advantages of this are the early detection of faults,reducing software development time etc.In recent times,researchers have considered different UML diagrams for generating test cases.In this paper,present an approach of generating test cases from activity diagrams using UML 2.0 syntax and with use case scope.Also consider a test coverage criterion,called activity path coverage criterion.Then the permutation of intercurrent activity was analyzed.Then BFS and DFS is used in the algorithm.It reduces the number of test cases,promotes the feasibility of automatic generating test case.At last,how to get test case from test scenario was discussed.Thereby automatic generating test case from UML activity diagram became systemic,feasible and effective.
