Research And Application Of Integration Testing Based On Component Software

In recent years,the integration testing techniques of component have become mature in many fields of research.Because of interaction,dependence on the context and the unknown source code of the component's characteristics,it's difficult to access communications from components developer,including some of the analytical data and the run-time status information of components for component users.So,interactivity of components and the integration of testing strategy based on component software is a key problem of component's testing,which due to development of component to a large extent.Firstly,the distinction between component software development(CBSD) and the development of traditional software development in system architecture and the process of development are analyzed.From the point of reuse,component-based software focused on the importance of reuse and facing the issues of testing.Secondly, combination of the actual project named Information Management System of Shaanxi Province for College Student(PCSIMS),the elements of integration testing in system architecture,modules and interface are analyzed.In the selection of integration testing' s strategy,the bottom-up,depth-first,breadth-first and the Big Bang strategies of integration in view of the PCSIMS' s actual constraints are analyzed and compared, and a better strategy of integration testing through comprehension of these different integration strategies is achieved.Aiming at the characteristics of component,the paper introduces the concept of hierarchical metadata,which can be fully described the information of component. Using the meta-model in UML architecture,which combines hierarchical metadata with UML use case,the UML meta-model which embedded metadata is constructed to achieve more interactive information of component.Finally,combining component case,hierarchical metadata's relation of component for student information's application named RegisterStuInfo in PCSIMS are deeply analyzed and researched.On the base of these researches,general scene is described.In additional,testing and test cases can be linked through the same StuCard information of component,so as to lay the foundation of the solution to the interaction of components and the interaction between component and the component-based software.
