如何使用 pytest 测试其视图具有 LoginRequired 和一些特定用户依赖项的视图

Question

我正在测试一个视图，但在测试时出现了这个错误

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

而且我认为我收到此错误是因为 request.user.profile.org 因为 mixer.blend(User) 将拍摄一些不在我的数据库中的用户意味着一些没有个人资料的用户，Org和很多东西。所以，我想知道如何测试此视图，如何为该用户提供一些配置文件和 Org（组织）。而且我这样做就像我正在获取数据库中某些用户的信息并将其传递给 #test_views.py -> test_dashboard_view()-> request.user 你可以检查在 test_dashboard_view() 我评论过的行......

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': 'nitin@gmail.com', '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

我得到了答案，实际上主要问题是重定向，因为@Brachamul 在那个问题中建议我，我被重定向到了其他地方，这造成了问题。因此，由于该观点，测试没有通过。谢谢你给我宝贵的时间。

Answer 2

您可以尝试 self.client.get() 方法，而不是将 request object 直接传递给 function based views，该方法将模拟真实的 request 到达您的 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/')

Answer 3

我知道您已经找到了答案，但对于遇到此问题的其他人，我建议使用 Client.force_login()

这是它如何工作的一个例子：

profile_url = reverse("forum:profile")
forum_user = ForumUser.objects.get(username="admin")
       
profile_data = dict(
    user=forum_user
)

self.client.force_login(forum_user)    
response = self.client.post(profile_url, data=profile_data)
