Well, I do so, but never for visual stuff.

I consider that impossible in practice and probably even in theory.

Example: Write a unit test that tests that in a treeview, 
the selected node actually is displayed with the bitmap 
indicated by SelectedIndex property of the node.

Write a unit test that tests that in a MessageDialog, the correct image is 
displayed on the buttons.

I'd really like to see those tests :-)

Lazarus IMHO has the best testsuite ever: 
An active community that points out bugs as soon as they pop up.
