No problem. @Luciano: I assume grok.grok_doctests() will be an alias for
grok.testing.grok_doctests() then. So you can use the namespace.

It's still not implemented, so no chance to get rid of it ;-)

Yes, they work fine. As Theuni already told, it is mainly a question of
finding tests, not running them.

The globs are an attribute of a testsetup instance. You can set it as
you like and they can also be passed as kwarg to the constructor.

A catch-all registerer like::

  grok.register_doctests('cave', globs={'sync': sync})

is therefore very easy to do.

This also applies to setup and teardown funcs.

I will, however, have a look at the ZODB tests to see, what complex
cases can arise.

I'm not sure, whether I understand correctly. Are you talking about
avoiding `globs` at all (at test registration time)?

Kind regards,
