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.
Please don't post an issue when you are not sure of your code, post a "Question". Issues are for problem of a kata not for problem in your code. There are no error in the tests, they are the same in all languages. BTW in your code I don't see any "cube".

Edit: now getting a timeout issue, so probably just a fluke.
