Mark,
After reading your project's description I realized that Dr. Gehringer (@efg) explicitly said to do these method name changes, so you're right in changing them to make more sense. Despite the fact that you didn't directly make the changes to the unit tests, the changes are still there and the tests are failing because RubyMine did not refactor the methods used in the tests properly. Fix these and the tests should pass and we can close the pull request.

Thanks,
Pam
