Unfortunately, no. And I don't see how it would be possible to write a test
for this either, as the file must be removed after auto-revert decides that
it should be reverted and before the actual revert takes place.

In real-life, I see it a couple of times each week. However, in my Emacs I
have opened files associated with processes that erase and rewrite them,
say, every ten seconds.
