Change Kata tests

# probably not the most DRY.
# you'd want to DRY it up just in case you screwed up 
# some of the test itself.
# i spent a good 40 minutes trying to work out where I went wrong.
# it turns out that the problem was not in the code, but in the tests!
# I had to skip all the tests to finally work out what was going on.
