The xUnit pattern is that if a test runs without an error or a failed
assertion, then the test passes.  An empty test function that does
nothing will meet this criterion, so it passes.

Ideally, an empty test wouldn't be a success, but I'm not sure how
the test runner could determine that it was empty.  I guess it could
introspect the test function to see if it had any real code in it,
but I don't know of a test runner that does that.
