I'm in the beginning phase of developing a webapp with Django. I'm using a headless selenium setup in Vagrant.

Accessing the pages works fine but in the following test it just hangs. I not sure whether this is due to compatibility between selenium and my firefox version.

The pip3 freeze of my test environment:

coverage==4.0.3
defusedxml==0.4.1
Django==1.9.1
django-allauth==0.24.1
oauthlib==1.0.3
psycopg2==2.6.1
python3-openid==3.0.9
requests==2.9.1
requests-oauthlib==0.6.0
selenium==2.49.0
wheel==0.24.0
xvfbwrapper==0.2.7

firefox -v

Mozilla Firefox 43.0.4

I'll start with the class I wrote to test allauth (Google login) than the specific function which hangs.

# -*- coding: utf-8 -*-
from django.contrib.staticfiles.testing import StaticLiveServerTestCase
from django.core.urlresolvers import reverse
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException
from xvfbwrapper import Xvfb

class TestGoogleLogin(StaticLiveServerTestCase):

    def setUp(self):
        self.vdisplay = Xvfb()
        self.vdisplay.start()
        self.browser = webdriver.Firefox()
        self.browser.maximize_window()
        self.browser.implicitly_wait(3000)
        self.browser.wait = WebDriverWait(self.browser, 5)

    def tearDown(self):
        self.browser.quit()
        self.vdisplay.stop()

    def get_element_by_id(self, element_id):
        return self.browser.wait.until(EC.presence_of_element_located(
                (By.ID, element_id)))

    def get_button_by_id(self, element_id):
        return self.browser.wait.until(EC.element_to_be_clickable(
                (By.ID, element_id)))

    def get_full_url(self, namespace):
        return self.live_server_url + reverse(namespace)

The following test hangs.

def test_google_login(self):
    self.browser.get(self.get_full_url("home"))
    google_login = self.get_element_by_id("google_login")
    with self.assertRaises(TimeoutException):
        self.get_element_by_id("logout")
    self.assertEqual(
        google_login.get_attribute("href"),
        self.live_server_url + "/accounts/google/login")
    google_login.click()
    with self.assertRaises(TimeoutException):
        self.get_element_by_id("google_login")
    google_logout = self.get_element_by_id("logout")
    google_logout.click()
    google_login = self.get_element_by_id("google_login")

The weird thing is if I take everything out and only run the first two sentences it passes. However, when I insert the with statement it hangs!

If I run the two first sentences and assertEqual the href attribute (so without the with statement and everything else) it passes. When I also add in the google_login.click it hangs again.

When I CTRL-C the test I get the following Traceback:

Hopefully someone is able to help me out with this. Thanks in advance!!

I had a problem with the firefox webdriver also. Try to downgrade your firefox to version 36. That's the last one that worked for me.
