Django Jenkins raises WebDriverException when processed to Selenium server

I start Selenium server hub by command

java -jar selenium-server-standalone-2.33.0.jar -role hub

and Selenium server node by command

  • django.db.utils.OperationalError: fe_sendauth: no password supplied
  • Git - How to deploy code from my central Git repo to my production server?
  • Got an import error all of a sudden
  • Seamless deployment of Django to single server
  • Deploying a local django app using openshift
  • Which PIP Returns Global Instead of VirtualEnv
  • java -jar selenium-server-standalone-2.33.0.jar -role node -hub http://localhost:4444/grid/register -browser browserName=htmlunit

    Then i’m trying to execute code:

    from selenium import webdriver
    from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
    server =  'http://localhost:4444/wd/hub'
    dc = DesiredCapabilities.HTMLUNIT
    browser = webdriver.Remote(server, dc)

    Everything is ok after this.
    But when i’m trying to start Jenkins test:

    from django.test import TestCase, LiveServerTestCase
    from selenium.webdriver.common import proxy
    from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
    from selenium.webdriver.remote.webdriver import WebDriver
    class SeleniumTest(LiveServerTestCase):
        def setUpClass(cls):
            p = proxy.Proxy({
            'proxyType': proxy.ProxyType().MANUAL,
            'httpProxy': '',
            capabilities = DesiredCapabilities().HTMLUNIT
            cls.selenium = WebDriver(desired_capabilities=capabilities, proxy=p)
            super(SeleniumTest, cls).setUpClass()
        def tearDownClass(cls):
            super(SeleniumTest, cls).tearDownClass()
        def test_javascript_basket(self):

    I’m getting following error, contained in traceback:

    WebDriverException: Message: u’\n\n\nERROR: The requested URL could not be retrieved\n\n\n\n

    What’s going on? Why connect to Selenium server from Jenkins test isn’t working?


    UPDATE: If i’m using Firefox WebDriver instead of HTMLUNIT, Firefox opens after line

    cls.selenium = WebDriver(desired_capabilities=capabilities, proxy=p)

    , but later raises above-described exception.

    I simply add to setUpClass() method:

    import os
    . . .
        def setUpClass(cls):
            os.environ['NO_PROXY'] = ''

  • Best Practice for following Subversion repository Trunk: Git (Mirror), Git-Svn, Subversion?
  • One Solution collect form web for “Django Jenkins raises WebDriverException when processed to Selenium server”

    I solved the problem this way (used a phantom-js instead of HTMLUNIT, because it’s the only remaining stable version of code).

    from django.test import LiveServerTestCase
    from selenium import webdriver
    from os import environ
    class SeleniumTestCase(LiveServerTestCase):
        __test__ = False    
        def setUpClass(cls):
            environ['NO_PROXY'] = ''  # The key point
            cls.selenium = webdriver.PhantomJS(service_args=['--proxy-type=none'])    
            super(SeleniumTestCase, cls).setUpClass()
        def tearDownClass(cls):
            super(SeleniumTestCase, cls).tearDownClass()
    class TestFoo(SeleniumTestCase):    
        def setUp(self):
            # do something before every test method runs
        def test_foo(self):
            # test
