+Live test server
+----------------
+
+.. versionadded:: 1.4
+
+.. currentmodule:: django.test
+
+.. class:: LiveServerTestCase()
+
+``LiveServerTestCase`` does basically the same as
+:class:`~django.test.TransactionTestCase` with one extra thing: it launches a
+live Django server in the background on setup, and shuts it down on teardown.
+This allows to use other automated test clients than the
+:ref:`Django dummy client <test-client>` such as, for example, the Selenium_ or
+Windmill_ clients, to execute a series of functional tests inside a browser and
+simulate a real user's actions.
+
+You may control which host and port the live server will run at with
+respectively the :setting:`LIVE_TEST_SERVER_HOST` and
+:setting:`LIVE_TEST_SERVER_PORT` settings. The full server url can then be
+accessed during the tests with ``self.live_server_url``.
+
+To demonstrate how to use ``LiveServerTestCase``, let's write a simple Selenium
+test. First of all, you need to install the `selenium package`_ into your
+Python path:
+
+.. code-block:: bash
+
+   pip install selenium
+
+Then, add the following code to one of your app's tests module (for example:
+``myapp/tests.py``):
+
+.. code-block:: python
+
+    from django.test import LiveServerTestCase
+    from selenium.webdriver.firefox.webdriver import WebDriver
+
+    class MySeleniumTests(LiveServerTestCase):
+        fixtures = ['user-data.json']
+
+        def setUp(self):
+            self.selenium = WebDriver()
+            super(MySeleniumTests, self).setUp()
+
+        def tearDown(self):
+            super(MySeleniumTests, self).tearDown()
+            self.selenium.quit()
+
+        def test_login(self):
+            self.selenium.get('%s%s' % (self.live_server_url, '/login/'))
+            username_input = self.selenium.find_element_by_name("username")
+            username_input.send_keys('myuser')
+            password_input = self.selenium.find_element_by_name("password")
+            password_input.send_keys('secret')
+            self.selenium.find_element_by_xpath('//input[@value="Log in"]').click()
+
+Finally, you may run the test as follows:
+
+.. code-block:: bash
+
+    ./manage.py test myapp.MySeleniumTests.test_login
+
+This example will automatically open Firefox then go to the login page, enter
+the credentials and press the "Log in" button. Selenium offers other drivers in
+case you do not have Firefox installed or wish to use another browser. The
+example above is just a tiny fraction of what the Selenium client can do; check
+out the `full reference`_ for more details.
+
+.. _Windmill: http://www.getwindmill.com/
+.. _Selenium: http://seleniumhq.org/
+.. _selenium package: http://pypi.python.org/pypi/selenium
+.. _full reference: http://readthedocs.org/docs/selenium-python/en/latest/api.html
+.. _Firefox: http://www.mozilla.com/firefox/
+
+.. note::
+
+    When running tests with an in-memory SQLite database, the same database
+    connection needs to be shared between the thread in which the tested code
+    is run and the thread in which the test case is run. By default, pysqlite
+    forbids connections being shared between multiple threads. To allow this
+    behavior you need to set the ``check_same_thread`` option in the
+    :setting:`DATABASES` setting to ``False``.
+
+    .. code-block:: python
+
+        DATABASES = {
+            'default': {
+                'ENGINE': 'django.db.backends.sqlite3',
+                'OPTIONS': {
+                    'check_same_thread': False,
