Because I never want my program to run after I run my unittests? If the
unittests pass, my program should be working, apart from things that are
impossible/hard to unittest.

That's one possibility. When I program, I aim for such coverage with my
unittests that running the program to see if things work is not necessary.
Hence, a more likely scenario:

1 Make change
2 Run unittests (quick)
3 If unittests fail, goto 1
4 Run normally (slow)
5 Goto 1

I have not once wanted to run both the full application and the unittests at
the same time. when I want to run the unittests, running the application would
be a waste of time. When I want to run the program, I don't care about the
unittests.
