[1.2.X] Fixed #3051 -- Documented the requirements for standalone testing....

but not gracefully. No details of the tests run before the interruption will

be reported, and any test databases created by the run will not be destroyed.

Running tests outside the test runner

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you want to run tests outside of ``./manage.py test`` -- for example,

from a shell prompt -- you will need to set up the test

environment first. Django provides a convenience method to do this::

    >>> from django.test.utils import setup_test_environment

    >>> setup_test_environment()

This convenience method sets up the test database, and puts other

Django features into modes that allow for repeatable testing.

The call to :meth:`~django.test.utils.setup_test_environment` is made

automatically as part of the setup of `./manage.py test`. You only

need to manually invoke this method if you're not using running your

tests via Django's test runner.
