Incorrect kata.
Since in the description it says "We need a function that receives two arrays arr1 and arr2, each of them, with elements that occur only once".
OCCUR ONLY ONCE!
But in the random tests there are a lot of repetitions. So be careful - you have to filter array first to leave just unique valu@es.
@raulbc777, you should change either description or tests.

Facing the same problem - seems like an issue with the kata.
