When I had a similar situation, I created a directory for testing that was
in a known state, and tested on that. If you can test based on a relative
directory, that should work OK.

Non-existant paths shouldn't be too hard to come up with; hardcoding a
constant relative dir of
"THISDIRECTORYCANTPOSSIBLYEXISTANDIFITDOESYOURENUTS" ought to do OK.
