Abstract: With the extensive application of the component-oriented software development methods, the description and test of the component systems is becoming the key of software quality assurance. For the particularity of the component system complexity and development methods, component systems’ integration test using traditional methods often face with many difficulties. This paper presents an improved test-oriented component describe model called TCSM. It focuses on the interactions and behavioral constraints between components in the component systems and provides a wealth of information for the phase of functional test and boundary test in system integration test. An approach to transfer the TCSM to test model, which based on UML collaboration diagram and supports the conversion of one component system from its description model to test model automatically, is also proposed in the paper. Furthermore, an algorithm for generating test cases automatically is realized. TCSM can better describe the interactive behaviors and realize the automatic test of component-based systems. The proposed model can not only reduce plenty of time in the process of system modeling and test, but also improve the efficiency and reliability of the component-based systems.
