god this is massive...

Hi, I got a weird error in test. It says test passed but then shows a failure which is not clear to me what it means.
For example, here is the test:

test.it("should be able to handle a list of length 6")
assert_linked_list_equals(alternating_split(build_one_two_three_four_five_six()).first, build_list([1, 3, 5]), "First list of alternating_split(1 -> 2 -> 3 -> ... 6 -> None) should be 1 -> 3 -> 5 -> None")

should be able to handle a list of length 6
Test Passed
First list of alternating_split(1 -> 2 -> 3 -> ... 6 -> None) should be 1 -> 3 -> 5 -> None: 5 should equal 3

It first has "Test PAssed"

But then shows the 2nd error msg. I don't understand what it means by "5 should equal 3". My list is exactly the same as the expected.

Please help!
Thank you!

TypeError: argument 2 to map() must support iteration

does anyone get above error ?

Same here.
Unless there is this line in the test, how is it going to succeed ?!
Primes = Primes()

I have the same problem! Shouldn't the test be front, back = front_back_split(source, front, back) such that front and back gets assigned? I passed all the run test by changing them to such but can't submit successfully because they are not assigined.

Maybe they could test something 100 times smaller with (linearly? quadratically?) proportionally less time for us test using 'Run tests', so that we have the benefit of not having to load 20MB of numbers.

is it possible to add the long test case to test?

"My below solution is to leave the "state" of the locker unchanged if the number of locker is a multiple of the run." I would say it's the other way around, i.e. on the 7th run he only alters the state of all multiples of 7. But I agree that kata description is a bit confusing.
