Test framework in VS 2K5

I've created several tests for one of my forms, via the "Create Tests..." menu in VS 2K5. Several of the tests that were created need to check the status or contents of controls on the form.
Via the accessor object I am able to see all methods and property of the form's controls. For some reason when I try to reference any of these properties, for example a textbox's "text" property, I get an error.
I've also noticed that form events do not fire during unit tests. If I expand a node in a treeview the "BeforeExpanded" event never fires.
What am I doing wrong? Am I failing to initialize or set something?

We dont directly support UI tests. Some people have had some mileage through probing the methods, but there are some subtle timing issues involved.

What exactly are you doing to cause the Event to be fired?
