如何使用pytest测试视图，该视图的视图具有LoginRequired和某些特定的用户依赖性 [英] How to test views with pytest whose views has LoginRequired and some specific user dependencies

问题描述

我正在测试一个视图，而在测试时却出现此错误

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

我认为由于request.user.profile.org而导致出现此错误，原因是mixer.blend(User)将显示一些不在我的数据库中的User，这意味着一些没有Profile，Org和许多其他用户的用户事物.因此，我想知道如何测试该视图，如何给该用户一些配置文件和Org(organization).而且我也这样做，就像我在数据库中获取某个用户的信息并将其传递给#test_views.py->一样. test_dashboard_view()->您可以在request.user中检入我已评论的行test_dashboard_view()....

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.......

@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)

推荐答案

我得到了答案，实际上主要的问题是重定向，因为@Brachamul在该问题中建议我

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.
