More yes for deeper stuff, more no for outer stuff. I have integrated testsuit for core framework components, which can be run separately, i tend to have separate tests for more upper level stuff, and i rarely have unit tests for actual programs. It tends to be a drag that is very easy to half-ass, so i try not to waste it.
