It was previously working only with attachments/detachments
to the live domain. Now it can test attaching/detaching to
the persistent domain too.

Indentation is off here.

No need to do default in case the switch condition is an enum, although
I'm not sure how that works with flags (non-continuous values).

We should also take into account the fact that it can be both, but
should not be _CURRENT in tests.  That way we don't have to do two lines
of DO_TEST_ATTACH_.  Although that might cause confusion with the 'keep'
parameter.
