Odd test output results about learn4haskell HOT 4 CLOSED

Hi @bitwombat 👋🏻

As you can see, the "expected" output "Bool -> Boolean -> Bool" is incorrect because Haskell doesn't have standard type Boolean and it should be Bool. In this context, "expected" is your code because this is "what you expect from the test" and "but got" is what GHC actually gives you.

The doctest output can be confusing but I hope my comment helps you a bit 🙂

Yes, an intentional injected error to show the problem.
That's backwards what all other testing frameworks use for 'expected' and 'actual' but I can calibrate myself.
Thanks!

Actually, shouldn't have closed it - the seemingly random order it's testing in (described in the original text) is also confusing for a newbie...

@bitwombat I believe, this is happening because doctest runs tests in a non-deterministic order. Probably for performance reasons. Unfortunately, nothing we can do here. I can recommend opening an issue in doctest if you want to discuss the possibility of having an option for running tests in a sequence.
