You need to specify a Content-Type in your POST request, e.g.:

         d = client.getPage(self.getURL("test"), method="POST",
                            postdata=urllib.urlencode({"test": "data"}),
                            headers={"Content-Type": "application/x- 
www-form-urlencoded"})

Otherwise, your POST request is sent as text/html, and the HTTP server  
code won't know to parse args out of the request body.

(Probably this should have gone to twisted-web rather than twisted- 
python, since in the end it wasn't really about trial, but http ;).
