Performing Combinatorial Testing on Web Service-Based Software

Although Web service-based software (WSBS) possesses a lot of merits such as loose coupling and good interoperability, its some new characters also bring challenges to latter maintenance activities inevitably. In the paper, we proposed a combinatorial testing framework for the WSBS, which mainly includes test cases generation and knowledge-based debugging. For the former, naive method and ldquogreedy+backtrackingrdquo method are addressed in detail. At the stage of debugging, rough set reasoning is adopted to generate association rules, which can help maintainers to locate faults in the WSBS by using dynamic slicing technology. In addition, the feasibility and effectiveness of our approach is validated by some working examples and experiments.
