This is for the fixed test where the input is the empty string "".

For this test, your code currently returns an empty list - [] - but the kata in fact wants you to return a list with an empty string inside it, like this - [""].

I personally agree that it's not very logical (and so do many other people if you read the entire Discourse page below) but that's what the kata wants in this case.

So you can "hard code" this particular input value, and you should be able to pass the rest of the kata.
