Nosetests猜数游戏

Question

我正在尝试为一个随机输入的数字游戏写几个测试，但不太确定如何继续。

我正在关注来自http://inventwithpython.com/chapter4.html的Python游戏

使用文件test_guess.py启动测试

from unittest import TestCase
import pexpect as pe

import guess as g

class GuessTest(TestCase):
    def setUp(self):
        self.intro = 'I have chosen a number from 1-10'
        self.request = 'Guess a number: '
        self.responseHigh = "That's too high."
        self.responseLow  = "That's too low."
        self.responseCorrect = "That's right!"
        self.goodbye = 'Goodbye and thanks for playing!'

    def test_main(self):
        #cannot execute main now because it will
        #require user input
        from guess import main

    def test_guessing_hi_low_4(self):
        # Conversation assuming number is 4
        child = pe.spawn('python guess.py')
        child.expect(self.intro,timeout=5)
        child.expect(self.request,timeout=5)
        child.sendline('5')
        child.expect(self.responseHigh,timeout=5)
        child.sendline('3')
        child.expect(self.responseLow,timeout=5)
        child.sendline('4')
        child.expect(self.responseCorrect,timeout=5)
        child.expect(self.goodbye,timeout=5)

    def test_guessing_low_hi_4(self):
        # Conversation assuming number is 4
        child = pe.spawn('python guess.py')
        child.expect(self.intro,timeout=5)
        child.expect(self.request,timeout=5)
        child.sendline('3')
        child.expect(self.responseLow,timeout=5)
        child.sendline('5')
        child.expect(self.responseHigh,timeout=5)
        child.sendline('4')
        child.expect(self.responseCorrect,timeout=5)
        child.expect(self.goodbye,timeout=5) 

和guess.py文件，其中

intro = 'I have chosen a number from 1-10'
request = 'Guess a number: '
responseHigh = "That's too high."
responseLow  = "That's too low."
responseCorrect = "That's right!"
goodbye = 'Goodbye and thanks for playing!'


def main():
    print(intro)
    user_input = raw_input(request)
    print(responseHigh)
    print(request)
    user_input = raw_input(request)
    print(responseLow)
    user_input = raw_input(request)
    print(responseCorrect)
    print(goodbye)

if __name__ == '__main__':
    main()

不确定如何继续使用if语句编写更多的测试，以测试值是低还是高。我被告知要尝试像optparse这样的命令行开关来传递数字，但我也不确定如何做到这一点。

作为一个Python新手，任何指导或帮助都将不胜感激。

为了在nosetest中执行命令行解析，您必须执行类似于this的操作(至少这是我必须做的)，例如，创建一个插件，让您能够访问nosetest中的命令行参数。一旦你添加了给你命令行参数的插件，就很容易创建一个测试来利用这个传入的参数。

from test_args import case_options

class GuessTest(TestCase):
...

    def test_guessing(self):
        # Conversation assuming number is 4
        if case_options.number < 4:
            # Do something
        elif case_option.number > 4:
            # Do some other test
        else: 
            # Do the final test

这有意义吗？我可能误解了你想要做的事情，如果是的话，请让我知道，希望我们能澄清这一点。
