I could, but it is not the idea of this test case. Actually, I'm assuming that it works correctly in order to test this. The proxy service has no port specified, and the attribute soapVersion="1.2". Without the fix, it will choose any port of the original WSDL to proxy, such as a Soap 1.1 port (and therefore the proxy service will only accept 1.1 requests). So sending a SOAP 1.2 request would make the test fail. With the fix, the service tries to select a port that matches the specified version, so it would choose the 1.2 port and the test will pass.
