SOAPUI is a java based tool for testing and working with any type of Web Service.  All that is needed is a WSDL file whether stored locally or remotely.  The program will read the WSDL and generate some mock code that can emulate a server or act as a client.   SOAPUI comes in two versions.   An open source version that is free, and provides most of the features one will need for testing Web Services.  It also comes in a Professional version which extends the testing suite ability and provides some further advanced features for running test suites.
