I'm not sure I understand... Do you mean that a previous test might have already created and left a directory with the same name behind, and then this 'mkdir' would error out and thus fail the test? If yes, then you're right with your nitpicking on my nitpicking ;) Though instead of 'rm -rf'ing that directory I would suggest 'mkdir -p' to simply ignore it if it were to exist.
