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

问题描述

您能帮我下一个吗? 我发现了问题，无法解决. 当我使用下一个代码时，浏览器已启动并且测试已通过:

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:\chromedriver\chromedriver.exe')
driver.get("site URL")

与类和方法相同，但返回消息:进程已完成，退出代码为0":

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:\chromedriver\chromedriver.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(带有方法和类)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

在通过 Selenium 使用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 :

• 在传递 Key executable_path时，请通过单引号和原始的r开关提供 Value .
• 在定义@Tests名称时，以 test 开头的测试，例如 def test_NoLorem(自己):
• 在调用get()时，请确保您传递的是有效的url，例如 http://www.python.org
• 在def tearDown(self):中调用quit()方法的同时，通过 WebDriver 实例将其作为self.driver.quit()调用.
• 如果您使用的是 unittest 模块，则必须通过如果__name__ =="__main__"来调用Tests:

• 这是您自己的代码，需要进行一些小的修改:

• 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:\Utility\BrowserDrivers\chromedriver.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()
