+GeoDjango Tests
+===============
+
+.. versionchanged:: 1.2.4
+
+GeoDjango's test suite may be run in one of two ways, either by itself or
+with the rest of Django's :ref:`unit-tests`.
+
+.. note::
+
+    The :setting:`TEST_RUNNER` previously used to execute the GeoDjango
+    test suite,:func:`django.contrib.gis.tests.run_gis_tests`, was deprecated
+    in favor of the :class:`django.contrib.gis.tests.GeoDjangoTestSuiteRunner`
+    class.
+
+Run only GeoDjango tests
+------------------------
+
+To run *only* the tests for GeoDjango, the :setting:`TEST_RUNNER`
+setting must be changed to use the
+:class:`~django.contrib.gis.tests.GeoDjangoTestSuiteRunner`::
+
+    TEST_RUNNER = 'django.contrib.gis.tests.GeoDjangoTestSuiteRunner'
+
+Example
+^^^^^^^
+
+First, you'll need a bare-bones settings file, like below, that is
+customized with your spatial database name and user::
+
+    TEST_RUNNER = 'django.contrib.gis.tests.GeoDjangoTestSuiteRunner'
+
+    DATABASES = {
+        'default': {
+            'ENGINE': 'django.contrib.gis.db.backends.postgis',
+            'NAME': 'a_spatial_database',
+            'USER': 'db_user'
+        }
+    }
+
+Assuming the above is in a file called ``postgis.py`` that is in the
+the same directory as ``manage.py`` of your Django project, then
+you may run the tests with the following command::
+
+    $ python manage.py test --settings=postgis
+
+Run with ``runtests.py``
+------------------------
+
+To have the GeoDjango tests executed when
+:ref:`running the Django test suite <running-unit-tests>` with ``runtests.py``
+all of the databases in the settings file must be using one of the
+:ref:`spatial database backends <spatial-backends>`.
+
+.. warning::
+
+    Do not change the :setting:`TEST_RUNNER` setting 
+    when running the GeoDjango tests with ``runtests.py``.
+
+Example
+^^^^^^^
+
+The following is an example bare-bones settings file with spatial backends
+that can be used to run the entire Django test suite, including those
+in :mod:`django.contrib.gis`::
+
+    DATABASES = {
+        'default': {
+            'ENGINE': 'django.contrib.gis.db.backends.postgis',
+            'NAME': 'geodjango',
+            'USER': 'geodjango',
+        },
+       'other': {
+            'ENGINE': 'django.contrib.gis.db.backends.postgis',
+            'NAME': 'other',
+            'USER': 'geodjango',
+       }
+    }
 
-To run GeoDjango's own internal test suite, configure the
-:setting:`TEST_RUNNER` setting as follows::
+Assuming the settings above were in a ``postgis.py`` file in the same
+directory as ``runtests.py``, then all Django and GeoDjango tests would
+be performed when executing the command::
 
-    TEST_RUNNER='django.contrib.gis.tests.run_gis_tests'
+    $ ./runtests.py --settings=postgis
