Generating test data based on XML Schema

The quality of Web service is widely concerned. The dynamic testing methods based on the specification are usually adopted because of the source codes even the executable codes of Web services under testing not being accessed by the tester. Now, the XML Schema is the basis for presenting the messages transferred between Web services and defining the structures and datatypes of document for specifying Web service. This paper presented a method which could generate test data based on XML Schema for testing simple Web service defined by WSDL and WSDL-S and composite web service defined by OWL-S and BPEL4WS. A prototype tool is implemented based on the approach.
