:point_right: Here's a couple of hints:

  • replace the "pass" placeholders in the sample code, don't add new cases
  • apply the assert to the result of calling the function being tested

If you're still stuck, here's a solution to task 1:

:warning: SPOILER ALERT

class PalindromeTestCase(unittest.TestCase):
    def test_good_palindrome(self):
        self.assertTrue(is_palindrome("tacocat"))  # this line replaces "pass"
