There is no such a test case in any languages, so resolving.

There is a test with zeroes(12, 27) though, and the expected result (11) is correct.

I print the base and number and the log say that it's 3 and 27

27! should have 13 zeroes indeed, but I have node idea how did you get this error.

In random tests number is randint(1000, 10000) and there are no hard-coded tests with zeroes(3, 27)

Are you sure you're solving this kata and not some of its kumite?

in python... it say that 13 should equals 11

Correct. And what do you get and in which language?

I think the 27! in base 3 should have 13 trailing zero. I have calculated it with online calculator and have that result
