<p>I'm using <a href="http://www.codeplex.com/bizunit" rel="noreferrer" title="BizUnit">BizUnit</a> to unit-tests my Biztalk orchestrations, but some orchestrations consume a WebService,and testing these seems more like integration testing than unit testing.</p>

<p>I'm familiar with using a mocking framework to mock the generated proxy objects, in order to test a web service from a Windows Forms application, but I would like to be able to do it in a more integrated way in a request-response port?</p>

<p>How would you approach this problem?</p>

This is a very interesting question that I still haven't seen a good generic answer to. Some people suggest using SoapUI but I haven't had time to actually test that yet.
This page
might be interesting on that.
Another way might be to somehow wrap the WebDev.WebHost.dll and use that ... Phil Hakkck discusses that in
this post
.
It's also be discussed before on SO
here
