+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):

+            call_command('closepoll', stdout=out)
