How to test views with pytest whose views has Logi

Question

I am testing a view and while testing this I am getting this error

self = <django.db.models.fields.AutoField: id>, value = ''

    def get_prep_value(self, value):
        from django.db.models.expressions import OuterRef
        value = super().get_prep_value(value)
        if value is None or isinstance(value, OuterRef):
            return value
>       return int(value)
E       ValueError: invalid literal for int() with base 10: ''

/usr/local/lib/python3.6/site-packages/django/db/models/fields/__init__.py:965: ValueError

And I think I am getting this error because of request.user.profile.org cause mixer.blend(User) will pic some User which is not in my database means some User which hasn't a Profile, Org and many things. So, I want to know that how do I test this view, how I give that user some profile and Org(organisation). And also I was doing this like I was taking the info of some User which is in my database and passing it to #test_views.py -> test_dashboard_view()-> request.user which you can check in test_dashboard_view() the lines I have commented.......

views.py

@login_required
def dashboard_view(request):
    org = request.user.profile.org
    week_responses = day_wise_responses(7, org)
    user_org = request.user.profile.org.name
    sms_sent = org.sms_counter
    email_sent = org.email_counter
    today = datetime.today().date()
    responses_one_week = number_of_responses(7, org)
    responses_two_week = number_of_responses(14, org)
    average_rating = org_average_rating(org)
    responses_last_week = responses_two_week - responses_one_week
    if responses_last_week:
        responses_percent_change = (abs(responses_one_week - responses_last_week)/responses_last_week)*100
    else:
        responses_percent_change = responses_one_week*100
    # last n responses
    last_5_responses = last_n_responses(5, org)
    # print(last_5_responses)
    context = {'week_responses': week_responses, 'user_org': user_org, 'today': today,
               'responses_one_week': responses_one_week, 'responses_percent_change': responses_percent_change,
               'last_5_responses': last_5_responses, 'sms_sent': sms_sent, 'email_sent': email_sent,
               'average_rating': average_rating}
    return render(request, 'events/dashboard.html', context)

urls.py

path('dashboard/', include('fancy_tsunami.events.urls')),

test_views.py

from events.views import dashboard_view
from django.test import RequestFactory
from django.urls import resolve, reverse
from django import test
import pytest
from django.contrib.auth.models import User, AnonymousUser


@pytest.mark.django_db
class TestViews(test.TestCase):
    def test_dashboard_view(self):
        path = reverse('event-dashboard')
        request = RequestFactory().get(path)
        # Org = [{'id': 1, 'name': 'Company', 'logo': None, 'share_google_url': None, 'sharing_destinations_id': None, 'sms_counter': 0, 'email_counter': 0}]
        request.user = mixer.blend(User)
        # CheckUser = {'id': 3, 'password': 'argon2$argon2i$v=19$m=512,t=2,p=2$bHZkZ3Q0bmE2bEJU$N6x/LFqwI4guA', 'last_login': None, 'is_superuser': True, 'username': 'nitin', 'first_name': '', 'last_name': '', 'email': '[e-mail]', 'is_staff': True, 'is_active': True, 'date_joined': datetime.datetime(2019, 2, 21, 1, 10, 32, 146)}
        # request.user = (CheckUser)
        response = dashboard_view(request)
        self.assertEqual(response.status_code, 200)

Answer 1

I got my answer actually the main problem was with redirection as @Brachamul suggested me in that question Testing whether a Url is giving 500 error or not in Django , I was being redirected somewhere else which was creating the problem. So the test was not getting passed because of that view. Thanks for giving me your precious time.

Instead of passing the request object directly to the function based views, you can try self.client.get() method which will simulate a real request coming to your views.

Django provides a test Client to simulate a user interacting with the code at the view level.

from django.test import Client
client = Client()
client.get('/path/to/your/views/')
