Fixed #23543 -- Added docs on testing management command output.

  differences when locales are changed and evaluate its impact on

  predictable behavior of your command.

Management Commands

-------------------

Management commands can be tested with the

:func:`~django.core.management.call_command` function. The output can be

redirected into a ``StringIO`` instance::

    from django.core.management import call_command

    from django.test import TestCase

    from django.utils.six import StringIO

    class ClosepollTest(TestCase):

        def test_command_output(self):

            out = StringIO()

            call_command('closepoll', stdout=out)

            self.assertIn('Expected output', out.getvalue())
