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.

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