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.

Should be fixed.
@zvytas is right. I've tweaked the stub function to be (a little) clearer on this.
Actually tests are correct. However, function declaration in this kata is a bit misleading - it gives an impression that items to insert will be passed as an array. That is not the case, the methods you're trying to write could be called like that:
splice(0, 1, 5, 6, 7, 8, .....)
So, in your specific case function was called like that:
splice(.., .., 5, 6);
Tests now fixed.
In that case, there may be some eroneous whitespace in there?
Fixed.
Thank you!
