Ruby 3.0 should be enabled (Refer this & this for more detail)

It is the way it is now because another PU preferred to see nothing unless tests failed. We really need some kind of guidelines on these as least as a reference. Check the updated test-description, it explicitly notes the amount of tests and the logging system.

To be clear, I don't have a preference either way, however if I change it to log all results, well I just have another PU making the exact opposite request as you just did.

you should change the assertion system so that one doesn't thnink there is only one random test:

if expected != actual then
  Test.assert_equals(actual, expected)
else
  Test.expect(true)
end

Added.

Needs random tests

Yes, codewars doesn't refesh your testcases if you already started this kata (all your input is saved, so you still get the older ones), but for new users the tests are correct now;-)!

In the example test cases, it still shows Test.expect(), but when I go to edit the kata as a contributor, it shows that it's already the correct Test.assert_equals(). Seems more like a Codewars bug, so resolving the issue. Thanks!

It's because of wrong tests;-):

    Text.expect(...) should be Test.assert_equals(...)

I just corrected it, you can mark issue as resolved;-)...
