Yes, but when we print something out we've run into some sort of problem
and then the test is over. So freeing the memory when it fails vs. when
the test is over seems like a minor difference. Or is it also used to
print other informational messages while the test is running?

I'm not particularly worried here, just trying to see if less code is
possible.
