Question

继续“艰难学习Python”练习47，我有以下项目框架。

ex47 
    bin/
    docs/
    ex47/
        __init__.py
    tests/
        __init__.py
        game_tests.py
    game.py
    setup.py

在Aptana Studio上工作。在game_tests.py中我有

from nose.tools import *
from 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.""")
    assert_equal(gold.name, "GoldRoom")
    assert_equal(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})
    assert_equal(center.go('north'), north)
    assert_equal(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})
    assert_equal(start.go('west'), west)
    assert_equal(start.go('west').go('east'), start)
    assert_equal(start.go('down').go('up'), start)

但Aptana无法定义“assert_equal”。我相信assert_equal是一个内置函数。有什么问题？

Answer 1

assert_equal位于nose.tools，但它不在__all__中，而不是在*中导入。尝试 from nose.tools import assert_equal

Aptana Studio没有找到'assert_equal'Python
