I fixed the failure message for the example test. I think that solves this. Closing.

I wasn't mutating the array but it was something else. The error message for the 3rd test is wrong when you click test but correct when you click attempt as the attempt tests have a different items array. It was only when I got some visibility that I was able to work out what was happening.

Test.assert_equals(items.contains_all?([9,2,5,4,10]), false, 'items.contains_all?([9,2,5,4,10] should have been true')

The test expects false, so the error message is wrong. Are you sure items array is the same in both tests? Are you mutating the array?

This test: items.contains_all?([9,2,5,4,10]), false, 'items.contains_all?([9,2,5,4,10] should have been true') is passing when I click test but failing when I click attempt. From what I can tell it should return false, which it does when I click test but when I click attempt it returns true. I'm assuming it's a bug/issue but I have no idea how to solve it. Anyone have any ideas? Thanks.

Thanks Pablo. My fault as I missed something in the instructions, ha ha! Now that I've sorted that, I'm getting closer to solving it. Thought I had but I need to fix one aspect of my logic. This is a good Kata though so thanks :)

No. "44421" should return "0" as stated by the rules.

I am doing this in Ruby and I believe there is an issue. This is test case 18: Test.assert_equals(points("44421"), 0) but I believe it should be returning 30 as there are 3 x 4s. I also noticed the input in this test is in the 0 point output section of the instructions so guessing someone has copied it from there to create the test. Please can this be fixed as currently I can't complete this Kata. Thank you.
