As with all applications, you need to test your Web service client. Before using your client, create some realistic test cases and make sure the client and Web service behave as expected. In addition to the normal OpenEdge tools for debugging applications, the ProSOAPView utility can be useful in testing your client. It provides a way to view SOAP messages. For more information on testing clients, see Testing and Debugging OpenEdge SOAP Web Services and Examples of ABL accessing a SOAP fault.
