Закрепляю свои знания основ python на codewars. Вроде бы задачу решил правильно, не могу понять, что от меня хочет

Инструкция: Your users' passwords were all stolen in the Yahoo! hack, and it turns out they have been lax in creating secure passwords. Create a function that checks their new password (passed as a string) to make sure it meets the following requirements:

Between 8 - 20 characters
Contains only the following characters (and at least one character from each category):
uppercase letters,
lowercase letters,
digits,
special characters from !@#$%^&*?
Return "valid" if passed or "not valid" otherwise.

Тесты базовые (он их проходит, а на рандомных заваливается):
test.describe('Basic Tests')
test.assert_equals(check_password(""), "not valid")
test.assert_equals(check_password("passw ord"), "not valid")
test.assert_equals(check_password("P1@p" ), "not valid")
test.assert_equals(check_password("P1@pP 1@p"), "valid")
test.assert_equals(check_password("P1@pP 1@pP1@pP1@pP1@pP1@p"), "not valid")
test.assert_equals(check_password("Paaaa aa222!!!"), "valid")

Все ошибки:
'valid' should equal 'not valid'
