Should read:
(I don't mind if the MR is a little larger, it should be as small as
possible but currently it looks like it's a little too small if it
doesn't include all the details for the tests too.)

Should read:
Diff lines 253 and 269 Helper methods:
  The helper methods should be public (shouldn't start with '_')

  They are also mixed in between test methods, they should be at the
  top of the class with the test methods following.
