Python/Django Test Framework: Response code was 200 (expected 200) - python

So I am using Django's test framework, and in this case im testing update_password_view that I ve created on top of the built-in PasswordChangeForm.
Could someone please help me with the error from below?
After I run tests I get the following error:
AssertionError: [] is not true : Response didn't redirect as expected: Response code was 200(expected 200)
Here is the code:
#views.py
class UpdatePassword(PasswordChangeView):
form_class = PasswordChangeForm
success_url = reverse_lazy('posts:home')
template_name = 'accounts/password.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
# get the number of unseen messages
context['inbox_count'] = Message.objects.filter(
~Q(sender=self.request.user), Q(seen=False),
(Q(chat__user1=self.request.user) |\
Q(chat__user2=self.request.user))).count()
return context
#tests.py
def test_update_password_view(self):
credentials = {
'old_password': '123secret',
'password1': '321secret',
'password2': '321secret',
}
response = self.client.post('http://127.0.0.1:8000/users/change-password/',
credentials, follow=True)
self.assertRedirects(response, '/posts/', status_code=200,
target_status_code=200)

status_code inside assertRedirects has to be redirect status code, which should be 3XX. In your occasion it has to be 302. See more at docs.
For the proper behaviour you should replace this:
self.assertRedirects(response, '/posts/', status_code=200, target_status_code=200)
With this:
self.assertRedirects(response, '/posts/', status_code=302, target_status_code=200)
By the way, it's similar to this:
self.assertRedirects(response, '/posts/')

This is not tested, but perhaps the issue is that it is not redirecting because the user is not created, or logged in with the old password. Try creating a user, logging them in, then running the test.
#tests.py
def test_update_password_view(self):
credentials = {
'old_password': '123secret',
'password1': '321secret',
'password2': '321secret',
}
# Create and login the user
self.client.user = User.objects.create(username="testuser", password="123secret")
c = Client()
logged_in = c.login(username='testuser', password='123secret')
response = self.client.post('http://127.0.0.1:8000/users/change-password/',
credentials, follow=True)
self.assertRedirects(response, '/posts/', status_code=302, target_status_code=200)

Django Rest Framework JWT Unit Test

I am using DRF with the JWT package for authentication. Now, I'm trying to write a unit test that authenticates itself with a JWT token. No matter how I try it, I can't get the test API client to authenticate itself via JWT. If I do the same with an API client (in my case, Postman), everything works.
This is the test case:
from django.urls import reverse
from rest_framework.test import APITestCase
from rest_framework_jwt.settings import api_settings
from backend.factories import member_factory
jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER
class MemberTests(APITestCase):
def test_get_member(self):
member = member_factory()
payload = jwt_payload_handler(member.user)
token = jwt_encode_handler(payload)
self.client.credentials(Authorization='JWT {0}'.format(token))
response = self.client.get(reverse('member-detail', kwargs={'pk': member.pk}))
assert response.status_code == 200
But I always get a 401 Authentication credentials were not provided.
In response.request I see the token is there, it's just not being applied I guess.
If I rewrite the test to use rest_framework.test.RequestsClient and actually send it to the live_server URL, it works.
Any help on this?
P.S.: I am aware of force_authenticate() and login, but I would like my unit tests to access the API the same as the API client will in production.
Try setting up a new APIClient for this test. This is how my own test looks like
def test_api_jwt(self):
url = reverse('api-jwt-auth')
u = user_model.objects.create_user(username='user', email='user#foo.com', password='pass')
u.is_active = False
u.save()
resp = self.client.post(url, {'email':'user#foo.com', 'password':'pass'}, format='json')
self.assertEqual(resp.status_code, status.HTTP_400_BAD_REQUEST)
u.is_active = True
u.save()
resp = self.client.post(url, {'username':'user#foo.com', 'password':'pass'}, format='json')
self.assertEqual(resp.status_code, status.HTTP_200_OK)
self.assertTrue('token' in resp.data)
token = resp.data['token']
#print(token)
verification_url = reverse('api-jwt-verify')
resp = self.client.post(verification_url, {'token': token}, format='json')
self.assertEqual(resp.status_code, status.HTTP_200_OK)
resp = self.client.post(verification_url, {'token': 'abc'}, format='json')
self.assertEqual(resp.status_code, status.HTTP_400_BAD_REQUEST)
client = APIClient()
client.credentials(HTTP_AUTHORIZATION='JWT ' + 'abc')
resp = client.get('/api/v1/account/', data={'format': 'json'})
self.assertEqual(resp.status_code, status.HTTP_401_UNAUTHORIZED)
client.credentials(HTTP_AUTHORIZATION='JWT ' + token)
resp = client.get('/api/v1/account/', data={'format': 'json'})
self.assertEqual(resp.status_code, status.HTTP_200_OK)
The following answer applies if you are using Simple JWT and pytest, and Python 3.6+. You need to create a fixture, I have called it api_client, and you need to get the token for an existing user.
from django.contrib.auth.models import User
from rest_framework.test import APIClient
from rest_framework_simplejwt.tokens import RefreshToken
import pytest
#pytest.fixture
def api_client():
user = User.objects.create_user(username='john', email='js#js.com', password='js.sj')
client = APIClient()
refresh = RefreshToken.for_user(user)
client.credentials(HTTP_AUTHORIZATION=f'Bearer {refresh.access_token}')
return client
Notice that in the fixture above, the user is created there, but you can use another fixture to create the user and pass it to this one. The key element is the following line:
refresh = RefreshToken.for_user(user)
This line allows you to create tokens manually as explained in the docs. Once you have that token, you can use the method credentials in order to set headers that will then be included on all subsequent requests by the test client. Notice that refresh.access_token contains the access token.
This fixture has to be used in your tests that you require the user to be authenticated as in the following example:
#pytest.mark.django_db
def test_name_of_your_test(api_client):
# Add your logic here
url = reverse('your-url')
response = api_client.get(url)
data = response.data
assert response.status_code == HTTP_200_OK
# your asserts
I had similar issue, enclosed I send you my solution just to have more code to compare (tests.py).
from django.urls import reverse
from rest_framework import status
from rest_framework.test import APITestCase
from django.contrib.auth.models import User
class AuthViewsTests(APITestCase):
def setUp(self):
self.username = 'usuario'
self.password = 'contrasegna'
self.data = {
'username': self.username,
'password': self.password
}
def test_current_user(self):
# URL using path name
url = reverse('tokenAuth')
# Create a user is a workaround in order to authentication works
user = User.objects.create_user(username='usuario', email='usuario#mail.com', password='contrasegna')
self.assertEqual(user.is_active, 1, 'Active User')
# First post to get token
response = self.client.post(url, self.data, format='json')
self.assertEqual(response.status_code, status.HTTP_200_OK, response.content)
token = response.data['token']
# Next post/get's will require the token to connect
self.client.credentials(HTTP_AUTHORIZATION='JWT {0}'.format(token))
response = self.client.get(reverse('currentUser'), data={'format': 'json'})
self.assertEqual(response.status_code, status.HTTP_200_OK, response.content)
Well, since i was using django unit test client, i just created a simple base test class with a bearer token property:
import json
from django.test import TestCase
from django.contrib.auth import User
from rest_framework.test import APIClient
from rest_framework_simplejwt.tokens import RefreshToken
class TestCaseBase(TestCase):
#property
def bearer_token(self):
# assuming there is a user in User model
user = User.objects.get(id=1)
refresh = RefreshToken.for_user(user)
return {"HTTP_AUTHORIZATION":f'Bearer {refresh.access_token}'}
In my django unit tests:
class SomeTestClass(TestCaseBase):
url = "someurl"
def test_get_something(self):
self.client.get(self.url, **self.bearer_token)
def test_post_something(self):
self.client.post(self.url, data={"key":"value"}, **self.bearer_token)
Inspired by #dkarchmer, this is my code working.
I am using a custom user model which the email is used for authentication.
Pay attention to using email field for authentication requests.
If I use username, the response is 400_BAD_REQUEST.
The 401_UNAUTHORIZED usually means the credentials are not correct or the user is not activated.
def test_unusual(self):
User = get_user_model()
email = 'user#test.com'
password = 'userpass1'
username = 'user'
user = User.objects.create_user(
username=username, email=email, password=password)
user.is_active = False
user.save()
obtain_url = reverse('token_obtain_pair')
resp = self.client.post(
obtain_url, {'email': email, 'password': password}, format='json')
self.assertEqual(resp.status_code, status.HTTP_401_UNAUTHORIZED)
user.is_active = True
user.save()
resp = self.client.post(
obtain_url, {'email': email, 'password': password}, format='json')
self.assertEqual(resp.status_code, status.HTTP_200_OK)
Postman interacts with your actual database. Django uses separate database for it's test case running. Therefore a new user record needs to be created again inside your test definition before authentication testing. Hope this helps.
I'm using DRF and simple-jwt and I had to use Bearer instead of JWT in the http auth header: HTTP_AUTHORIZATION=f'Bearer {token}'
Full code:

response = self.client.post(url, jwt_fetch_data, format='json')
token = response.data['access']
self.client.credentials(HTTP_AUTHORIZATION=f'Bearer {token}')
def test_post(self):
response = self.client.get('/some-url/',
data={'format': 'json'}
)
self.assertEqual(response.status_code, status.HTTP_200_OK)

Wrong Behaviour doing tests on Django

I'm having problems to do test on Django. I've been reading the documentation of the responses and I can't do the same as they explain on the documentation.
When I get the response, I only have access to response.status_code and can't access to context or redirect_chain when I write response.(and now PyCharm shows all available options).
I've checked on settings.py and I've 'BACKEND': 'django.template.backends.django.DjangoTemplates' to be sure that I'm using Django templates so I don't know why don't work the test. I need configure something?
The code of the test I'm trying to do it's:
from django.test import TestCase
from django.test.client import Client
class Test(TestCase):
def testLogin(self):
client = Client()
headers = {'X-OpenAM-Username': 'user', 'X-OpenAM-Password': 'password', 'Content-Type': 'application/json'}
data = {}
response = self.client.post('/login/', headers=headers, data=data, secure=True, follow=True)
assert (response.status_code == 200)
# self.assertRedirects(response, '/menu/', status_code=301, target_status_code=200)
I'm not using Django authentication, the login form sends the data to an IDP and if the IDP sends with a correct answer, the "login" it's successful:
def login(request):
logout(request)
message = None
if request.method == "POST":
form = LoginForm(request.POST)
if form.is_valid():
username = request.POST['username']
password = request.POST['password']
headers = {'X-OpenAM-Username': username, 'X-OpenAM-Password': password, 'Content-Type': 'application/json'}
data = {}
req = requests.post('http://openam.idp.com:8090/openamIDP/json/authenticate', headers=headers, params=data)
if req.status_code == 200:
respJson = json.loads(req.content)
tokenIdJson = respJson['tokenId']
request.session['tokenId'] = tokenIdJson
return render_to_response('menu/menu.html', request)
elif req.status_code == 401:
message = "Invalid username and/or password. Please, try again"
else:
form = LoginForm()
return render_to_response('registration/login.html', {'message': message, 'form': form},
context_instance=RequestContext(request))
The redirect assert it's commented because now it fails, when I do the debug I see an empty redirect_chain. I don't understand why happens this because running the web everything works, all views redirect as expected.
Why I only can check status_code? I'm doing something wrong when I redirect after a successful login that on a normal use it works but on the test not?
Thanks.
The remote authentication url expects the credentials as headers, but your local login view expects them as POST data. Your test passes the credentials as headers to your local view.
As a result, the form is passed an empty dictionary (request.POST contains no actual data), and the form is invalid. You get an empty form as a response, without any redirects.
You have to simply pass the credentials as post data to your local view:
def testLogin(self):
client = Client()
data = {'username': 'user', 'password': 'password'}
response = self.client.post('/login/', data=data, secure=True, follow=True)
assert (response.status_code == 200)
self.assertRedirects(response, '/menu/', status_code=301, target_status_code=200)

Django / DjangoRestFramework - unittest not authenticating user created using ORM

This is my test:
class PageTests(APITestCase):
def setUp(self):
Location.objects.create(locationName = 'Location of Mine', LocationCode = 'LOM')
User.objects.create(username='b', password='b', email='b#hotmail.com')
def test_create_page(self):
"""
Ensure only authenticated users can create a new page object.
"""
url = reverse('page-list')
# See if unauthenticated unadmin users can create a page (they shouldn't.)
data = {'location': 1, 'pageName': 'Test Page 1', 'pageDescription': 'This is the first test page', 'pageCode': 'TP1'}
response = self.client.post(url, data, format='json')
self.assertEqual(response.status_code, status.HTTP_403_FORBIDDEN)
# See if authenticated users can create a page (they should).
print(User.objects.get().username)
self.client.login(username='b', password='b')
response = self.client.post(url, data, format='json')
print(response.data)
self.assertEqual(response.status_code, status.HTTP_201_CREATED)
This is my views.py / viewset:
class IsAuthenticated(permissions.BasePermission):
def has_permission(self, request, view):
print('here!!!!!!!!!!!!')
print(request.user)
return request.user.is_authenticated()
class pageViewSet(viewsets.ModelViewSet):
queryset = Page.objects.all()
serializer_class = PageSerializer
permission_classes = (IsAuthenticated,)
The problem is, even after I log the user in by doing self.client.login(username='b', password='b') it still raises a 403 error when posting. This is what gets printed:
here!!!!!!!!!!!!
AnonymousUser
b
here!!!!!!!!!!!!
AnonymousUser
{'detail': 'Authentication credentials were not provided.'}
As you can see, Django does see the user object (because it prints 'b') but the user does not get signed in for some reason and is still an AnonymousUser. Now, when I change my setup to this:
def setUp(self)
url = reverse('user-list')
# Create the user using the API.
data = {'username': 'b', 'password': 'b', 'email': 'a#hotmail.com', 'location': '1'}
response = self.client.post(url, data, format='json')
self.assertEqual(response.status_code, status.HTTP_201_CREATED)
and then log the user in, it work perfectly fine and the test doesn't raise any errors. Any idea why it raises errors when creating the user using User.objects.create()?
I've used similar code before in other unittest classes (creating the user using the ORM and then signing him in) and it works. I'm not sure why it's not working here.
Edit: Also, if I create the user and make him a super user and log him in, like so:
User.objects.create_superuser(username='a', password='a', email='a#hotmail.com')
it works as well.
Found the answer. I had to create the user by doing this:
User.objects.create_user()
and not this:
User.objects.create()

django how to set request user in client test

I am testing a view and my test looks like:
def test_profile(self, user_id):
user = User.objects.create_user(username="myusername", password="password", email="abc#testmail.com")
self.client.user = user
print(user.id)
request = self.client.get("/account/profile/{}/".format(user_id), follow=True)
self.assertEqual(request.status_code, 200)
Here my profile view has a login_required decorator. How can I set user to request.user?
I was trying to do the same myself but found out that Django Test Client does not set the user in the request and it is not possible to set request.user while using Client any other way. I used RequestFactory to that.
def setUp(self):
self.request_factory = RequestFactory()
self.user = User.objects.create_user(
username='javed', email='javed#javed.com', password='my_secret')
def test_my_test_method(self):
payload = {
'question_title_name': 'my first question title',
'question_name': 'my first question',
'question_tag_name': 'first, question'
}
request = self.request_factory.post(reverse('home'), payload)
request.user = self.user
response = home_page(request)
More about request factory here
Try this:
from django.test import TestCase, Client
from django.contrib.auth.models import User
class YourTestCase(TestCase):
def test_profile(self, user_id):
user = User.objects.create(username='testuser')
user.set_password('12345')
user.save()
client = Client()
client.login(username='testuser', password='12345')
response = client.get("/account/profile/{}/".format(user.id), follow=True)
self.assertEqual(response.status_code, 200)
Here, I first create the user and set the login credentials for the user. Then I create a client and login with that user. So in your views.py, when you do request.user, you will get this user.
If you use django.test you can do something like that:
self.client.force_login(user)
This works:
self.client.force_authenticate(user=user)
If you have a response, you can access response.context['user'].
If you need a response object, just call any view that will create a context, e.g. response = self.client.get('/').

Registration Facebook user with Django Allauth

I tried to use Django AllAuth to make a registration user by Facebook.
I have to make a REST API so I would to use Django REST Framework.
I found this simple tutorial to make the first user registration but probably there are some difference from current implementation:
I tried this code:
def post(self, request):
data = JSONParser().parse(request)
access_token = data.get('access_token', '')
try:
app = SocialApp.objects.get(provider="facebook")
token = SocialToken(app=app, token=access_token)
# check token against facebook
login = fb_complete_login(app, token)
login.token = token
login.state = SocialLogin.state_from_request(request)
# add or update the user into users table
ret = complete_social_login(request, login)
# if we get here we've succeeded
return Response(status=200, data={
'success': True,
'username': request.user.username,
'user_id': request.user.pk,
})
except:
traceback.print_exc()
return Response(status=401, data={
'success': False,
'reason': "Bad Access Token",
})
but now I see that fb_complete_login take 3 parameters: request, app and token.
So, I tried to put also the request like this function parameter but some lines later I have an error on login = fb_complete_login(app, token).
TypeError: add_message() argument must be an HttpRequest object, not
'Request'.
Any suggestions are welcome!
Solution given here: http://tech.agilitynerd.com/django-rest-registration-with-django-rest-auth.html
To disable messaging just for allauth, override the adapter (for instance in main.adapters):
from allauth.account.adapter import DefaultAccountAdapter
class MessageFreeAdapter(DefaultAccountAdapter):
def add_message(self, request, level, message_template,
message_context=None, extra_tags=''):
pass
then add this in settings.py:
ACCOUNT_ADAPTER = 'main.adapters.MessageFreeAdapter'
