"MoveTests has no attribute 'rock'"

Thanks in advance for your help! I'm trying to follow the video and I believe my script is identical to Kenneth's, however, when i run the script i get the errors:

Traceback (most recent call last):
File "tests.py", line 21, in test_equal
self.assertEqual(self.rock, moves.Rock())
AttributeError: 'MoveTests' object has no attribute 'rock'

Traceback (most recent call last):
File "tests.py", line 21, in test_equal
self.assertEqual(self.rock, moves.Rock())
AttributeError: 'MoveTests' object has no attribute 'rock'

see below for my code:

import unittest

import moves

class MoveTests(unittest.TestCase): def setUp(self): self.rock = moves.Rock() self.paper = moves.Paper() self.scissors = moves.Scissors()

class MoveTests(unittest.TestCase): def test_five_plus_five(self): assert 5 + 5 == 10

def test_one_plus_one(self):
    assert not 1 + 1 == 3

def test_equal(self):
    self.assertEqual(self.rock, moves.Rock())

def test_not_equal(self):
    self.assertNotEqual(self.rock, self.paper)

if name == 'main': unittest.main()

Your only issue is that you are creatign MoveTests twice. It won't call the setUp from the first class from the second class. You'll simply need to combine the two classes.

import unittest
import moves

class MoveTests(unittest.TestCase):

    def setUp(self):
        self.rock = moves.Rock()
        self.paper = moves.Paper()
        self.scissors = moves.Scissors()

    def test_five_plus_five(self):
        assert 5 + 5 == 10

    def test_one_plus_one(self):
        assert not 1 + 1 == 3

    def test_equal(self):
        self.assertEqual(self.rock, moves.Rock())

    def test_not_equal(self):
        self.assertNotEqual(self.rock, self.paper)

if name == 'main':
    unittest.main()

That worked, thanks!
