Integration Testing Research For EJB Component-Based System

The component-based software development has been adopted rapidly, but component-based system testing still faces a lot of questions. Therefore, this paper researchs on test case generation in integration testing of component-based system..There are some relationship between component-based systems and OO-based systems in testing. OO system testing takes important in its characteristics ,such as hereditability polymorphism and dynamic banding, but component-based system testing usually focuses on software structure,state and interaction. This paper mainly researchs on component configuration testing,state testing and interaction testing. In configuration testing, this paper analyses types of configuration. Mutation testing is used to component configuration feature. Because of separate of state variable and behavior, this paper depict how to catch test information from component specification and interface and generate test trees in component state testing. Test cases can automatic generated by test trees. In component interaction testing, test cases is obtained by CIG according to four component testing element. But because of content relationship is not easy to reflect in CIG, this paper propose to generate test cases by SBCIM model.Finally, this paper discusses current existed questions about component system integration testing and research directions in the future. It can offer guidance.
