笨办法学python3 习题47 自动化测试

本习题是习题46 的拓展，实际的测试了一个简单的类Room。

下面是本习题的目录框架：

上面的.pyc后缀都是运行自动化测试之后，产生的文件。

setup.py：

try
    from setuptools import setup
except ImportError:
    from distutils.core import setup

config = {
    'description' : 'My Project',
    'author' : 'Gabe',
    'author_email' : '[email protected]',
    'version' : '0.1',
    'install_requires' : ['nose'],
    'packages' :['ex47'],
    'scripts' : [],
    'name' : 'black_hole'
}
setup(**config)
           

game.py:

class Room(object):
    def __init__(self, name, description):
        self.name = name
        self.description = description
        self.paths = {}#This is a dict
    def go(self, direction):
        return self.paths.get(direction,None)
    def add_paths(self, paths):
        self.paths.update(paths)
           

ex47_tests.py

from nose.tools import *
from game import Room #从顶层目录导入模块时候，不用加ex47
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)
           

最后的运行结果：

用到的py字典方面的语法：

dict.get(key, default = None)
#key值，字典中要查找的键，None是找不到键的时候，返回的默认的值。
           

dict.update(dict2)
#添加到指定字典dict里的字典dict2，该方法没有返回值。
           

断言：

总结：算是对自动化测试目录的一个简单应用。
