Python 名称错误 : global name 'assertEqual' is not defined

Question

我正在学习《艰难地学习 Python》，并且正在进行练习 47 - 自动化测试 (http://learnpythonthehardway.org/book/ex47.html)

我使用的是 Python3(与书中使用的 Python 2.x 相比)，我意识到 assert_equals(书中使用的)已被弃用。我正在使用 assertEqual。

我正在尝试构建一个测试用例，但出于某种原因，在 cmd 中使用 nosetests 时，出现错误:NameError: global name 'assertEqual' is not defined

代码如下:

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)

我已经尝试在 GitHub 上搜索任何解决方案，但我不确定为什么它会给我 NameError 以及我将如何修复它。

python selenium 测试脚本中的第二个模块也有类似的问题。通过包含“ self ”来解决它。在“assertIn”之前。

之前:

assertIn('images/checkbox-checked.png', ET)

之后:

self.assertIn('images/checkbox-checked.png', webelement)
