On the other hand, my impression from writing tests was that sometimes it
would be advantageous
to have some prepared location with everything, so I would like to go in
the way of supporting different locations rather then requiring all tests
to use only data their generate in the preparation phase.

Would be nice to have something that run independently from the

unittest test which does not rely on location/mapset is probably the
default and preferred way, so I'm looking forward to see this.

easy as writing bash script and you get doctest functionality and Python
functionality to examine your results. The testing framework (perhaps
unittest class inside some script) would run the doctest file in the right
environment (location) or in several environments if desired.
