How to avoid getting the object `` NoneType 'does not have the attribute' path '' on selenium quit ()?

Question

When running Selenium Webdriver, the Python script receives the 'NoneType' object has no attribute 'path' after executing self.driver.quit(). . The Enclosing self.driver.quit() application in try/except does not help, namely:

 $ cat demo_NoneType_attribute_error.py # -*- coding: utf-8 -*- from selenium import webdriver import unittest class TestPass(unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() def test_pass(self): pass def tearDown(self): print("doing: self.driver.quit()") try: self.driver.quit() except AttributeError: pass if __name__ == "__main__": unittest.main() $ python demo_NoneType_attribute_error.py doing: self.driver.quit() 'NoneType' object has no attribute 'path' . ---------------------------------------------------------------------- Ran 1 test in 19.807s OK $ 

Does anyone know how to avoid the message 'NoneType' object has no attribute 'path' ?

Note:
Since this question was already reported by the beginning of November (see URL below), it should have had a patch by now, but updating selenium to the last of pip did not fix it.

• AttributeError exception: "'The NoneType object does not have the' path 'attribute in
• AttributeError exception: "'The NoneType object does not have the' path 'attribute in

Environment: Selenium 3.0.2; Python 2.7 Cygwin 32 bit on Windows 7.

Answer 1

selenium 3.0 seems to be a bug

Update the definition of the quit() method in webdriver.py of firefox as follows (relative path: ..\Python27\Lib\site-packages\selenium\webdriver\firefox\webdriver.py ):

change the following line in the quit() method:

 shutil.rmtree(self.profile.path) #which gives Nonetype has no attribute path if self.profile.tempfolder is not None: shutil.rmtree(self.profile.tempfolder) 

to

 if self.profile is not None: shutil.rmtree(self.profile.path) # if self.profile is not None, then only rmtree method is called for path. if self.profile.tempfolder is not None: shutil.rmtree(self.profile.tempfolder) # if tempfolder is not None, then only rmtree is called for tempfolder. 

Note : wherever self.profile used, do the same. those. move the code to the state indicated above.

In selenium 3.0 , profile and binary moved to firefox_options instead of their separate existence as firefox_profile and firefox_binary respectively in Selenium 2.0 .

you can check this in webdriver.py (of firefox ) in the __init__ method.

the corresponding code in the __init__ method:

 if firefox_options is None: firefox_options = Options() print dir(firefox_options) # you can refer binary and profile as part of firefox_options object. 

Note. It has been observed that firefox_options.profile still sets to None , which may be a problem to fix in selenium 3.0
