管理命令可以用 ​call_command()​ 函数来测试。输出可以重定向到 ​StringIO​ 实例中：

from io import StringIO
from django.core.management import call_command
from django.test import TestCase

class ClosepollTest(TestCase):
    def test_command_output(self):
        out = StringIO()
        call_command('closepoll', stdout=out)
        self.assertIn('Expected output', out.getvalue())
