Research And Application Of Class Integration Testing Strategy Based On Test Order

With the development of software technology and the increment of software project scale, the effect of software testing becomes more and more important. Object-oriented technology brings new challenges to software testing and object- oriented integration testing is necessary to object-oriented software testing. At present, some object-oriented integration strategies are put forward, but they still have some questions. This paper focuses on the class integration testing strategy based on test order and brings forth a new integration testing strategy based on object model relation diagram.At the beginning, this paper introduces the software testing technology and test order. On the software testing technology, we introduce the concepts and phases and generalize the integration testing strategy. On the test order, we introduce the concepts and the essential to test order. We also introduce the integration testing strategy based on object relation diagram and analyze the fault.Secondly, the paper proposes object model relation diagram(OMRD). OMRD that is based on the object relation diagram(ORD) combines with design model to form a new object relation diagram. According to the requires of OMRD, we analyze the class dependency relations in UML and put forward how class dependency relations determine to the test order in UML. Then we sum up the test order of staple design models. We discuss cycle breaking arithmetic based on test stub and illustrate the generation of OMRD.Thirdly, on the basis of OMRD, we propose the test order generation based on OMRD. We analyze the thought, process and define complete test order in modules that probably possess indirect dependency relations. Then we construct sorting tree to calculate test order and illustrate the test order generation based on OMRD.Finally, the paper uses this method in'SD Air Logistics Import and Export Management System'and compares it with other methods. Then we give out the experiment results. The results prove that integration testing strategy based on object model relation diagram can generate complete test order and is a relative perfect method. The method has some practical values and is valuable to be investigated further.
