Abstract
Recently with the rapid growth of network and changes of business environment, the enterprises require the integration of various information systems and their interoperation. The SOA (service oriented architecture) based on Web services is widely used for integration of these information systems. And as the standard integration language for the business processes, BPEL (business process execution language) provides the way to integrate various services provided by the information system. Over the past few years, some types of studies have been made on testing compatibility, discriminating, and tracing of processes in the services composition area. But there were few efforts to solve the problems caused by composition of various services. Especially, there is no effort to test and to enhance the robustness of the services composition. In this paper, we suggest a framework for the robustness testing of the service composition based on WS-BPEL. It generates the virtual testing environment. Through this framework, we can verify the robustness of Web services compositions against various errors and/or exceptional cases.
