Python + WebDriver — No browser launched while using unittest module

问题

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")

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()

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

Thanks a lot for any help.

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

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()

I'm not sure as I haven't tested it but I suspect the browser is still opened from the first code. So what I suggest here is to use driver.close() to terminate the process properly once you get out of script.

import unittest
from selenium import webdriver
driver = webdriver.Chrome('D:\chromedriver\chromedriver.exe')
driver.get("site URL")
driver.close()  # Must be there

Similarly, you can make modification in the test script to put self.driver.close() in the tearDown method.
