Yes, and also functional tests for some things that haven't caused bugs 
in the past, but are sorts of things that often do would also be good to 
make functional unit tests for (such as, spells and ranged weapons fired 
infront of map edges). Also, even for the non-functional unit tests, the 
functions will often need a set of data to operate within, and this 
would in many cases, mean a map.
