如何通过命令行将 url 作为参数传递给运行 selenium python 测试用例

Question

有什么正确的方法可以在 cmd 中使用获取 url 作为 testcases.py 文件的参数吗？

我正在运行在 cmd 中向 python 文件的运行测试用例下命令： testcases.py"any url"

testcases.py有编码：

class JSAlertCheck(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome("E:\chromedriver.exe")
        self.url = sys.argv[1]

    def test_Case1(self):
        driver = self.driver

    def tearDown(self):
           self.driver.quit()

if __name__ == "__main__":
    unittest.main(sys.argv[1])

Answer 1

根据 Python unittest passing arguments 的讨论，Python 专家 似乎表达了：

Unit tests should be stand-alone which will have no dependencies outside of their setUp() and tearDown() methods. This is to make sure that each tests has minimal side-effects and reactions to the other test. Passing in a parameter defeats this property of unittest and thus makes them sort of invalid. Using a Test Configuration would have been the easiest way and more appropiate as a unittest should never rely on foreign data to perform the test.

如果您仍想这样做，这里是一种可行的解决方案：

代码块：

from selenium import webdriver
import unittest
import sys


class MyTest(unittest.TestCase):

    URL = "foo"

    def setUp(self):
        self.driver = webdriver.Chrome(executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
        driver = self.driver
        driver.get(self.URL)

    def test_Case1(self):
        driver = self.driver
        print(driver.title)

    def tearDown(self):
        self.driver.quit()

if __name__ == "__main__":
    if len(sys.argv) > 1:
        MyTest.URL = sys.argv.pop()
    unittest.main()

CLI 命令：

python unittest_cmdline_urlASarguments.py http://www.python.org

输出：
