Hi,

Well, it's better, but still not really ok

• random tests aren't random at all. But since you cover the whole valid domain, it's ok. The test block name should be changed, tho.
• just DON'T create one it block per test, it's cluttering the console for no reason. the dop describe one should be an it block.
• the task is still not really interesting
• what's the "wrong" function for...? => to remove.

This will probably not survive the beta phase. You could keep the kata as drafts and send the direct link to your friends. They won't be able to "submit final", but they could train on the kata without it being published, this way.

Cheers

• No basic tests
• No random tests

Please read carefully the documentation before publishing other katas: https://docs.codewars.com/authoring/kata
