python - selenium testing with django gives 'NoneType' object has no attribute 'path' -

i cannot see making error happen because not give me more information. tests pass, print message console. post files below.

tests.py:

class mainapptests(liveservertestcase):     """testing interactions on main page"""      def setup(self):         """opening browser"""         selenium_logger = logging.getlogger('selenium.webdriver.remote.remote_connection')         # display possible problems         selenium_logger.setlevel(logging.error)         self.browser = webdriver.firefox()         self.user = make_user()      def teardown(self):         """closing browser"""         self.browser.quit()      def test_homepage(self):         """testing work"""         self.browser.get(self.live_server_url)         self.assertin("site", self.browser.title) 

views.py:

def home(request):     """view displaying home page"""     if request.user.is_authenticated():         # pulling , ordering 'full_name' field, shows users available         active_languages = language.objects.filter(active=true).order_by('full_name')         context = {'active_languages': active_languages}         return render(request, 'main/home_loggedin.html', context)     return render(request, 'main/home_loggedout.html', status=302) 

it's not you, it's selenium... :) code correct.

this recent issue selenium, happening python client during self.browser.quit().

updating selenium should trick. although due recent nature of bug (reported , fixed on 21th oct), @ moment, fix not yet incorporated recent version of selenium. should be fixed on versions above 3.0.1
