According to the documentation you can nicely test your WS client using http://docs.spring.io/spring-ws/site/apidocs/org/springframework/ws/test/client/MockWebServiceServer.html server.
But there is one precondition your client has to
// MyWebServiceClient extends WebServiceGatewaySupport, and is configured in applicationContext.xml
private MyWebServiceClient client;
No. The spring-ws-test module is specific to Spring-WS and cannot be used with other frameworks. You can use SoapUI for that, for instance.
