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.
Same problem here. When I use the "testthat" library on my machine and run the exact same testing code it works fine. It throws the same error as you posted when I run it on Codewars.
