Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Getting
#<NoMethodError: undefined method `expect' for main:Object Did you mean? exec>when trying to pass with any Ruby solution. I have verified my solution is correct in my own Terminal. When resetting and trying again, the error persists with both the test and attempt. Something wrong with the test cases?
