An Approach to Testing Based Component Composition

The key factor of component based software development is component composition technology. Although many researches have focused on this subject, the quality of system that is composed of components has not been guaranteed indubitably. Test-driven development (TDD) is a software development methodology for achieving high reliability. The combination of these two technologies will help to locate the component mismatch early and reduce the cost of system testing. In this paper, according to the components interaction graph we analyze the processes of testing based components composition (TBCC) and introduce the method as well as propose an algorithm. By applying testing ideas to component composition, it helps to control the composition process and lay foundation for high quality component software.
