title: Python NameError: global name 'assertEqual' is not defined
body: <p>I'm following Learn Python the Hard Way and I'm on Exercise 47 - Automated Testing (<a href="http://learnpythonthehardway.org/book/ex47.html" rel="noreferrer">http://learnpythonthehardway.org/book/ex47.html</a>)</p>
  
  <p>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.</p>
  
  <p>I am trying to build a test case but for some reason, when using nosetests in cmd, I get the error: <code>NameError: global name 'assertEqual' is not defined</code></p>
  
  <p>Here is the code:</p>
  
  <pre><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)
  </code></pre>
  
  <p>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.</p>
