 If you want to run the full suite of tests, you'll need to install a number of
 dependencies:
 
+*  Pillow_
 *  PyYAML_
+*  pytz_
 *  setuptools_
 *  memcached_, plus a :ref:`supported Python binding <memcached>`
 *  gettext_ (:ref:`gettext_on_windows`)
-*  selenium_ (if also using Python >= 2.6)
+*  selenium_
+
+You can find these dependencies in `pip requirements files`_ inside the
+``tests/requirements`` directory of the Django source tree and install them
+like so::
+
+    pip install -r tests/requirements/py2.txt  # Python 3: py3.txt
+
+You can also install the database adapter(s) of your choice using
+``oracle.txt``, ``mysql.txt``, or ``postgres.txt``.
 
 If you want to test the memcached cache backend, you'll also need to define
 a :setting:`CACHES` setting that points at your memcached instance.
 
+To run the GeoDjango tests, you will need to :doc:`setup a spatial database
+and install the Geospatial libraries</ref/contrib/gis/install/index>`.
+
 Each of these dependencies is optional. If you're missing any of them, the
 associated tests will be skipped.
