Ah I understand now. Yes, tests for Node 8 worked differently, they did not require to use the require, but I think now docs on testing in Node 8 are not easily accessible anymore and it's not clear how to add own tests.

The issue is valid, the kata should be either bumped up to Node 18, or some sample tests should be added. I will try to fix it later, or re-raise the issue with a proper description.

While this is true that this kata is not available in Node 18, enabling it still might not help. If you are trying to require a module which is not listed as supported by CW environment, enabling new Node will not help you. What module are you trying to require?
