    return requests.get(url).status_code


class ExampleTest(TestCase):

    @patch('requests.post')
    @patch('requests.get')
    def test(self, mock_requests_get, mock_requests_post):
        mock_request = Mock()
        mock_request.status_code = 200
        mock_requests_get.return_value = mock_request

        status_code = get()
        self.assertEqual(status_code, 200)
        self.assertTrue(mock_requests_get.called)
        self.assertEqual(1, mock_requests_get.call_count)
        mock_requests_get.assert_called_with('http://example.com')

        self.assertFalse(mock_requests_post.called)
