Python + WebDriver -- 使用 unittest 模块时没有启动浏览器 [英] Python + WebDriver -- No browser launched while using unittest module

问题描述

你能帮我做下一个吗?我发现了问题，但无法解决.当我使用下一个代码时，浏览器已经启动并且测试通过了:

Could you please help me with the next. I found out the issue and could not resolve it. When I am using next code, the browser has started and the test has passed:

import unittest
from selenium import webdriver
driver = webdriver.Chrome('D:chromedriverchromedriver.exe')
driver.get("site URL")

但与类和方法相同，返回消息:进程以退出代码 0 完成":

BUT same with class and methods return message: "Process finished with exit code 0":

import unittest
from selenium import webdriver
class GlossaryPage(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome(executable_path='D:chromedriverchromedriver.exe')
        self.driver.maximize_window()
        self.driver.implicitly_wait(10)
    def NoLorem(self):
        driver = self.driver
        driver.get("site URL")
    def tearDown(self):
        unittest.quit()

如何使用第二种情况(使用方法和类)打开浏览器?

How can I get the browser opened using 2nd case (with methods and class)?

非常感谢您的帮助.

推荐答案

在使用 Selenium 处理 Python 的 unittest 模块时，您必须考虑以下几个事实:

While working through Python's unittest module with Selenium you have to consider a few facts as follows :

• 当您传递 Key executable_path 时，通过单引号和原始 r 开关提供 Value.
• 在定义 @Tests 时，测试以 test 开头的名称，例如def test_NoLorem(self):
• 当您调用 get() 时，请确保您传递的是有效的 url，例如http://www.python.org
• 当您在 def tearDown(self) 中调用 quit() 方法时: 通过 WebDriver 实例作为 调用该方法self.driver.quit().
• 如果您使用 unittest 模块，则必须通过 if __name__ == "__main__":
调用 Tests

• 这是您自己的代码，并进行了必要的小修改:

• While you pass the Key executable_path provide the Value through single quotes along with the raw r switch.
• While you define the @Tests name the tests starting with test e.g. def test_NoLorem(self):
• While you invoke get() ensure you are passing a valid url e.g. http://www.python.org
• While you invoke the quit() method within def tearDown(self): invoke the method through the WebDriver instance as self.driver.quit().
• If you are using unittest module you have to call the Tests through if __name__ == "__main__":

• Here is your own code with the required minor modifications :

import unittest
from selenium import webdriver

class GlossaryPage(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Chrome(executable_path=r'C:UtilityBrowserDriverschromedriver.exe')
        self.driver.maximize_window()
        self.driver.implicitly_wait(10)
    def test_NoLorem(self):
        driver = self.driver
        driver.get("http://www.python.org")
    def tearDown(self):
        self.driver.quit()

if __name__ == "__main__":
    unittest.main()
