Question

我正在尝试为随机输入数字游戏编写一些测试，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

开始测试

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)

和带有

的guess.py文件

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语句编写一些测试来测试值是低还是高。我被告知要尝试像optparse这样的命令行开关传递数字，但不知道如何做到这一点。

对于使用Python的新人来说，任何指导或帮助都会受到赞赏。

为了在nosetests中进行命令行解析，你必须做类似于this的事情（至少这是我必须做的事情），即创建一个允许你访问命令的插件nosetests中的行参数。一旦你添加了插件给你命令行参数，创建一个可以利用参数传递的测试将非常容易。

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？我可能会误解你要做的事情，如果我是，请告诉我，希望我们可以清理它。
