Me neither. The docs should be updated.

I don't think so. The only chance to get a reference to the tests (and
update the globs) is to create a custom setup function using ':setup:'
markers (AFAIS).

I wonder, whether there is a special reason for testing layers not to
deliver the single tests to the setup code of layers (although this is
not the scope of z3c.testsetup).
