In attemting to automate a test on a Silverlight application, there is a 'Waiting' popup that is appearing after a button is clicked. I'm used to testing these sort of things from former client/server testing using Rational Robot, but am lost on this one. Can anyone point me in the right direction, or direct me to some literature that would explain some of the nuances of Silverlight testing / Web GUI testing vs. Client/Server testing? I'm very familiar with wait states, focus, etc., but I can't seem to a) nail down when this popup is gone, and b) know when the last object on the window under test is done being presented, for a lack of better term.
Thanks!
