You are  right. Basic purpose of unit testing is to check the functions
for correctness and prevent regression after future modifications. But
it's also quite common to write unit test that test the behaviour of the
integrated system. They then do test on a full life cycle of code. This
is mainly used when bugs have been identified.
But it is also incorrect to think functionnal unit test would not
require maps. Some methods in code can not work properly without a map
(like all get/put_ob_in_map()).
Functional tests will never be complete (you can't cover all game
situation, but you can cover all methods), that does not mean we
shouldn't write them as they are about as easy to write as unit one, and
use the same framework. I even think we should start by writing a few
functionnal unit tests based on current sourceforge bugtrack, while in
parallel begin to write unit tests to cover each crossfire function.
