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.

I agree. I don't know what TestTools is, exactly. In order to work on this offline, I had to rewrite the tests to use CollectionAssert instead. Katas should not have external dependencies that aren't provided. Maybe TestTools is something that Codewars offers, but I just can't locate.
When I tried it, it acted like it had no idea what the dictionary specified in the instructions was, so I just dropped one in on my own. I see that it worked for other users, but this is just what I had to do. I may try it again now that I see it's working for others.
