I honestly don't recall if that has been the case, sorry.
When I saw the procided solutions from other users I also
realized that it didn't matter what the input number was
but I just felt it wasn't very well stated in the description.
So I got a bit confused.

So either a number is dividable by 3 "or" 5 or if it's not dividable by neither
3 or 5 it wants the program to return 0 as it seems because that's what my code does.
As an example, if you used the number 23 as input it would neither be dividable
by 3 or 5 so it would return 0 and apparently the test doesn't seem to care about
that or sees that as correct.

But it wants you to find the sum of all the multiples of 3 or 5 less than the input number. It doesn't matter if the input itself if a multiple of 3 or 5 or whatever.

23 should return the sum of all numbers below 23 that are multiples of 3 or 5

Out of curiosity, did you get an error message like: "(some number) should equal 23"?

The description of this Kata wasn't very clear on what the result should be
in my opinion, first of all in the description it said 3 "or" 5 but down in
the test section it said 3 "and" 5. So I passed the Kata and here is what
I "think" it wants as a result.

So either a number is dividable by 3 "or" 5 or if it's not dividable by neither
3 or 5 it wants the program to return 0 as it seems because that's what my code does.
As an example, if you used the number 23 as input it would neither be dividable
by 3 or 5 so it would return 0 and apparently the test doesn't seem to care about
that or sees that as correct.

This makes the task very confusing since one can't be sure if all the conditions were met
and if you actually did it right and succeeded or if ones hacky approach just circumvented
the test with approaches that it "should've" caught if they weren't correct.

So I'm not very fond of the in my opinion unclear and incomplete description of the Kata
and I feel like the tests haven't been testing all the potential outcomes.
but all in all it was ok, I'd say.
