Testing Component-Based Software

Component-based software development facilitates software reuse and promotes productivity and quality. Although much work has been proposed for building component-based systems, techniques of testing component-based systems have not been well developed. In this paper, we present a technique for component-based software in integration testing. Our approach uses both static and dynamic analysis to guide test case generation. Static analysis captures the interaction relationship among the components, which is used to investigate what needs to be tested. Dynamic analysis keeps track of the interface invocations as well as event triggering for each test executed, and the information is used to determine test adequacy. The methodology proposed is efficient and effective, as demonstrated by the promising results obtained from an empirical study. *
