Recently, I have developed a npm package WSDLStubGen to generate WSDL request and response xml’s for mocking. This is similar to SOAP UI request generator. SOAP UI generates only a request xml but not response one. The response xml is important when setting up mockup for wsdl service.
The npm package is located at https://www.npmjs.com/package/wsdlstubgen
The source code is located at https://github.com/rajbandi/wsdlstubgen
