Python + WebDriver -- No browser launched while using unittest module

Question

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.

• Martin Schmelzer: For me chromeOperator = GlossaryPage() and chromeOperator.setUp() works just fine.
• Ben.T: if you repalce setUp by __init__ then, when creating an instance of GlossaryPage it will open a browser
• Sylvan LE DEUNFF: no it's unittest specific

Answer 1

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()
  

Answer 2

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.

• MaNKuR: Check the link, probably it will help
• Martin Schmelzer: Help with what? I have no problem :)
• MaNKuR: Thought its OP who replied here. Never mind ignore my comments. and yes you are correct it will just keep open one at a time.

Answer 3

In unittest, you have to put the tested code in method called

test_<custom_text_here>

Moreover I believe you wanted to quit the driver and not unittest? Try to replace the line

unittest.quit()

With

self.driver.close()
