A Regression Testing Method for Composite Web Service

Web Services (WS) is a popular way of implementing SOA-based software, which gained rapid progress. Several Web Services are usually combined to create new services by a mechanism named Composite Web Service. Composite Web Service is one of the most important components to WS.Composite Web Services testing is a difficult topic in WS testing. In this paper, we present a regression testing method for Composite Web service. The method can instruct the tester in locating fault in Composite Web Service, and make test data and test behavior independent of each other. We developed a prototype, and put a system under testing into practical use, the result indicates the method is effective to Composite Web service testing.
