I have now published SOAPe, the SOAP (EWS) test application that I previously blogged about up to Codeplex.  Documentation and updates will follow in due course.

I have also written a WebDAV test application that works in a very similar way, but supports WebDAV verbs and HTTP header modification (basically so that you can send any WebDAV request you need).  Also supported is a UDP listener, which means it can be used to test UDP notifications (as implemented in Exchange).
