I think I recall Scott mentioning that gMock shouldn't be used in UI code. 
Rather than mocking out these methods, you can provide protected setters that
test code can call into.

[csharp, 2013/01/16 20:56:58]

Removed the two new mocks I had added.

nit: Extra newline.

nit: Closing paren should be on the previous line; the rest should be indent
four spaces from the first "E" of "EXPECT_CALL"

Hmm, this puts the element completely off screen, right?  IMO it would be good
to also test with it partially off screen.

[csharp, 2013/01/16 20:56:58]

Added two tests for the popup only going partially off.
