True, but then you wouldn't know whether the higher level test
failed because of a bug in the higher level code or a bug in
the lower level code. The higher level test only says something
like "I've failed test XXX" it doesn't say "I can't run test XXX
because test YYY failed". So, instead of first debugging
lower level test YYY, XXX's author would start searching for a
"false" bug in XXX. THat wastes time.

I know of no such tests.
