What a nice kata.

python new test framework

What happens to sort method on array for JS with this kata ?
Array.sort is not working and leave array unmodified. Kata does not specify blocking anything

Approved

Lua translation!

when it seems you are doing the right thing and tests says no.
then you make such hard code

def sort_by_bit(arr):
    return [1, 2, 3, 4, 5, 6]

and the tests say that they don't care what you return.

That may be subjecive, but given that there are mentions in description of constraints that include arrays of length ~100_000, that in itself should suggest "performance".

please add a performance tag! С++ big_random_tests is impossible to pass without optimization

• "Your function shouldn't return anything".

In JS, if a function doesn't explicitly return a value, it still returns 'undefined' by default. So, a function always returns something.

there's a link under the comment that says "View Solution"

that link is only there when someone has the right language selected and has already solved/forfeited the kata for that language. Besides, since it fetches the solution of your most recent attempt (regardless of whether it passes or not), it is not reliable.

Anyways, I completely rewrote the C tests suite, it should be OK now (old solutions are still passing, at least the author's)

I did say it was C and there's a link under the comment that says "View Solution" that always changes to the most recently attempted & passing one if it matches the language you selected above. I didn't think to post a direct link but I couldn't have anyway-- the 3 passing attempts on my own list of solved katas don't have the Discuss link, only Refactor, presumably because I didn't Submit. I'm sorry for not starting with the TL;DR: and only getting to it in edits after trying more things I could have tried sooner.

Okay, the tests suite in C is seriously messed up. I have to rewrite it from scratch.

how am i supposed to debug anything with that kind of issue report ? you basically say "my solution was not supposed to pass but passed, there might be something wrong, or maybe not, and i'm not giving a link to my solution" :(

Very nice kata.
