Question

我无法确定如何测试基于Django类的视图是否从URL模式接收到预期的kwargs。

如果我有urls.py：

from django.conf.urls import url
from myapp import views

urlpatterns = [
    # ...
    url(
        regex=r"^people/(?P<pk>\d+)/$",
        view=views.PersonDetailView.as_view(),
        name='person_detail'
    ),
]

我的views.py：

from django.views.generic import DetailView
from myapp.models import Person

class PersonDetailView(DetailView):
    model = Person

我可以测试对URL的请求是否调用了正确的视图：

from django.test import TestCase
from django.urls import resolve
from myapp import views
from myapp.factories import PersonFactory

class UrlsTestCase(TestCase):

    def test_person_detail_view(self):
        PersonFactory(pk=3)
        self.assertEqual(resolve('/people/3/').func.__name__,
                         views.PersonDetailView.__name__)

但我也想测试/people/3/的请求会导致{'pk': '3'}传递给PersonDetailView，而我无法确定基于类的视图接收kwargs以便测试它（通过修补接收方法，我猜）。

以下是我在视图中检查id或pk的方式（我正在使用Django1.11）：

from menus.models import Item
from menus.views import ItemListView
from django.test import RequestFactory
from django.contrib.auth.models import User


person = User.objects.get(username='ryan')
factory = RequestFactory()

request = factory.get('/items/')
request.user = person

response = ItemListView.as_view()(request)

#prints the id or pk of the requesting user
response._request.user.pk
response._request.user.id

如何测试基于Django类的视图接收正确的参数？
