Once you've developed your Web service, you'll want to test it before you or someone else attempts call it from a client application. SOAP/AM Server does not provide a service testing tool at this time, but there a number of no-cost third-party tools available. Given a WSDL file, these tools can dynamically generate a client application that will invoke a method on your Web service.
