Unfortunately the Julia unit test is very unexpressive and only prints a message on a failure. However, I've changed how the test names are shown (now they are findmincost(money, days, cost) --> expected). The only other option I can think of would be to assign them to variables which look like the test names you suggest (e.g. Cheapest_day_rental = findmincost(money, days, cost) -> Cheapest_day_rental --> expected. Also, I've added the length of the cost array to the extra large random tests. Let me know what if you have any other thoughts. Cheers!

Edit: While the changes I made show up here, they don't appear on the kata or in the run output. Not sure why
