SharpRobo - another way to test GUIs

SharpRobo is another interesting way to test your win forms application, it uses recorder (test classes) to allow user operations to be replayed.

The potential issue for me is that you need to derive your forms and controls from SharpRobo base classes, it remains to be seen how much this is a limitation, but will worth a good look to see if it can work on  GUI projects
