Question

出于某种原因，我在尝试将命令行参数与我的单元测试一起使用时遇到了问题。

简单地说，我想要的只是在我的所有测试中使用env。我在这里做错了什么？

# -*- coding: utf-8 -*-
import argparse
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys
import unittest, time, re

class mySmokeTest(unittest.TestCase):
    def __init__(self, args):
        self.env = args.env

    def setUp(self):
        self.driver = webdriver.Firefox()
        self.base_url = "http://google.com"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_add_to_cart(self, env):
        # open base page
        driver = self.driver                    
        driver.get("{0}".format(env))

    def tearDown(self):
        self.driver.quit()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument('env', default='environment to test against')
    args = parser.parse_args()
    env = args.env
    runner = unittest.TextTestRunner()
    itersuite = unittest.TestLoader().loadTestsFromTestCase(mySmokeTest)
    runner.run(itersuite)

错误：

self.env = args.env
AttributeError: 'str' object has no attribute 'env'

我实际上并不知道为什么......但是将主要内容改为：

if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument('env', default='url to test against')
    args = parser.parse_args()
    env=args.env
    mySmokeTest.env = env
    runner = unittest.TextTestRunner()
    itersuite = unittest.TestLoader().loadTestsFromTestCase(mySmokeTest)
    runner.run(itersuite)

请注意：

    mySmokeTest.env = args.env does not work

如何在unittest中使用命令行参数？
