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.
Get started now by creating a new collection.

Have the same issue and I dont see that the output of the failing tests gives any useful information. Please modify the tests. I will skip this kata for now...
