Python NameError: global name 'assertEqual' is not defined
I'm following Learn Python the Hard Way and I'm on Exercise 47 - Automated Testing (http://learnpythonthehardway.org/book/ex47.html)
I am using Python3 (vs the book's use of Python 2.x) and I realize that assert_equals (which is used in the book) is deprecated. I am using assertEqual.
I am trying to build a test case but for some reason, when using nosetests in cmd, I get the error: NameError: global name 'assertEqual' is not defined
Here is the code:
from nose.tools import *
from ex47.game import Room
def test_room():
gold = Room("GoldRoom",
""" This room has gold in it you can grab. There's a
door to the north. """)
assertEqual(gold.name, "GoldRoom")
assertEqual(gold.paths, {})
def test_room_paths():
center = Room("Center", "Test room in the center.")
north = Room("North", "Test room in the north.")
south = Room("South", "Test room in the south.")
center.add_paths({'north': north, 'south': south})
assertEqual(center.go('north'), north)
assertEqual(center.go('south'), south)
def test_map():
start = Room("Start", "You can go west and down a hole")
west = Room("Trees", "There are trees here. You can go east.")
down = Room("Dungeon", "It's dark down here. You can go up.")
start.add_paths({'west': west, 'down': down})
west.add_paths({'east': start})
down.add_paths({'up': start})
assertEqual(start.go('west'), west)
assertEqual(start.go('west').go('east'), start)
assertEqual(start.go('down').go('up'), start)
I've tried searching GitHub for any solutions, and I'm just not sure why it's giving me the NameError and how would I go about fixing it.
assertEqual is a method of unittest.TestCase class, so you can only use it on objects that inherit from that class. Check the unittest documentation.
Had a similar problem with the second module in a python selenium test script. Solved it by including 'self.' before the 'assertIn'.
Before:
assertIn('images/checkbox-checked.png', ET)
After:
self.assertIn('images/checkbox-checked.png', webelement)
