I do not think it is so bad to be defensive to "prepare it cleanly enough so that I would not be affected". So "rm -fr repo && git init repo" I would fully support. "init && test_when_finished" is totally indefensible. It should be the other way around.

Those who run tests in a batch without "-i" would have more material to study and find breakages if you did so. I agree that is probably something worth doing (unless in narrow corner cases where each test repository consumes unusual amount of storage or somethinglike that).
