How can I call CXF Endpoint manually with String as SOAP Message

I would like to make a test of the webservice without putting it into server. I have my Endpoint from spring:

<jaxws:endpoint id="authorizationServiceEndpoint_v1" implementor="#AuthorizationService_v1" address="/AuthorizationService_v1">

and I have prepared my test message

<soapenv:Envelope bla bla >

How can I pass my message to the Enpoint and make it execute (and get result)?

Please avoid comments like "it's not the way you should test it" :)
