Correct answer part 2 import unittest

from string_fun import is_palindrome

class PalindromeTestCase(unittest.TestCase): def test_good_palindrome(self): self.assertTrue(is_palindrome('tacocat'))

def test_bad_palindrome(self):
    self.assertFalse(is_palindrome())

This would work I think, but a more authentic test is to supply a non-palindrome as the argument, e.g.

def test_bad_palindrome(self):
    self.assertFalse(is_palindrome('qwerty'))
