Django Invalid HTTP_HOST header: 'testserver'. You may need to add u'testserver' to ALLOWED_HOSTS

I started learning Django, I'm in the middle of implementing "Test a view" functionality.
When I use test Client in the shell, the exception has occurred as follows.

Invalid HTTP_HOST header: 'testserver'. You may need to add u'testserver' to ALLOWED_HOSTS.

I run the command in the shell as follows.

>>> from django.test.utils import setup_test_environment
>>> setup_test_environment()
>>> from django.test import Client
>>> client = Client()
>>> response = client.get('/')
>>> response.status_code
400


In the tutorial, 404 should be appeared, but I get 400.
When I continue running the command as follows, same exception has occurred.

>>> response = client.get(reverse('polls:index'))
>>> response.status_code
400


but the result must be 200.I guess I should declare ALLOWED_HOSTS in the settings.py, but how can I?
I run the server on localhost using $python manage.py runserver.

I wanna know the reason and solution.

Here is settings.py as follows.

import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
SECRET_KEY = '8v57o6wyupthi^#41_yfg4vsx6s($1$x0xmu*95_u93wwy0_&u'
DEBUG = True
ALLOWED_HOSTS = [127.0.0.1,'localhost']
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
]
.... (MIDDLEWARE)
ROOT_URLCONF = 'tutorial.urls'

TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': ,
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]

WSGI_APPLICATION = 'tutorial.wsgi.application'
.... (DATABASES, AUTH_PASSWORD_VALIDATORS)
LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = True

USE_TZ = True

ALLOWED_HOSTS = ['127.0.0.1', 'localhost']


put it like this

ALLOWED_HOSTS = ['XXX.iptime.org', 'localhost', '127.0.0.1', 'testserver']


# Application definition

INSTALLED_APPS = [
'polls.apps.PollsConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]


You should edit it like that:

ALLOWED_HOSTS = [
'172.0.0.1',
'localhost',
'testserver',
]

settings.py is in read-only mode

ALLOWED_HOSTS = ['127.0.0.1', 'localhost']


this is how to save it
