make tests run with representable-1.8.
require minitest/autorun as it has been telling me for a year.
test Rails 4.1.
add a 4_1 version strategy which consists of an angry comment, only. it is really time to simplify rails' renderer internals as they do _way_ too much.
use Artist.all.
add ::rails4_1?
manually add hal renderer for 4.1 test. sorry for that inconvenience but i don't wanna add that to the core until i understand/rewrote the respective core "components".
