Contract-based combined component interaction graph generation

Abstract

Component interaction graph is used to describe the interrelation of components, which provides an objective basis and technology to test component composition. However, the traditional component interaction graph cannot serve as a basis to test a component itself and the state transition between components for lacking of description of states of individual component. Therefore, a novel model, named Contract-Based Combined Component Interaction Graph (CBCCIG) is put forward in this paper. CBCCIG combined the thought of contract test with the UML state diagram which is introduced in the paper. The proposed model can not only support the quick assembly of the software system depending on developer's own willing, but also the automatic or semi-automatic generation of test cases which are the state transition and information interaction between components. Thus, CBCCIG improves the efficiency of development and testing. © 2013 Springer Science+Business Media New York.
