Login with code when using LiveServerTestCase with Django

You can't login user from selenium driver. It's just impossible without some hacks.

But you can login once per TestCase by moving it to setUp method.

You can also avoid copy-pasting by creating your class inherit from LiveServerTestCase.

UPDATE

This code worked for me:

self.client.login(username=superuser.username, password='superpassword') #Native django test clientcookie = self.client.cookies['sessionid']self.browser.get(self.live_server_url + '/admin/')  #selenium will set cookie domain based on current page domainself.browser.add_cookie({'name': 'sessionid', 'value': cookie.value, 'secure': False, 'path': '/'})self.browser.refresh() #need to update page for logged in userself.browser.get(self.live_server_url + '/admin/')

In Django 1.8 it is possible to create a pre-authenticated session cookie and pass it to Selenium.

In order to do this, you'll have to:

1. Create a new session in your backend;
2. Generate a cookie with that newly created session data;
3. Pass that cookie to your Selenium webdriver.

The session and cookie creation logic goes like this:

# create_session_cookie.pyfrom django.conf import settingsfrom django.contrib.auth import (    SESSION_KEY, BACKEND_SESSION_KEY, HASH_SESSION_KEY,    get_user_model)from django.contrib.sessions.backends.db import SessionStoredef create_session_cookie(username, password):    # First, create a new test user    user = get_user_model()    user.objects.create_user(username=username, password=password)    # Then create the authenticated session using the new user credentials    session = SessionStore()    session[SESSION_KEY] = user.pk    session[BACKEND_SESSION_KEY] = settings.AUTHENTICATION_BACKENDS[0]    session[HASH_SESSION_KEY] = user.get_session_auth_hash()    session.save()    # Finally, create the cookie dictionary    cookie = {        'name': settings.SESSION_COOKIE_NAME,        'value': session.session_key,        'secure': False,        'path': '/',    }    return cookie

Now, inside your Selenium tests:

#selenium_tests.py# assuming self.webdriver is the selenium.webdriver obj.from create_session_cookie import create_session_cookiesession_cookie = create_session_cookie(    username='test@email.com', password='top_secret')# visit some url in your domain to setup Selenium.# (404 pages load the quickest)self.driver.get('your-url' + '/404-non-existent/')# add the newly created session cookie to selenium webdriver.self.driver.add_cookie(session_cookie)# refresh to exchange cookies with the server.self.driver.refresh()# This time user should present as logged in.self.driver.get('your-url')

There is a library available on GitHub for this purpose: django-selenium-login
