Fixed #19196 -- Added test/requirements

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.
