How to create a Django REST Framework View instance from a ViewSet class?

Question

I'm trying to unit test Django REST Framework view set permissions for two reasons: speed and simplicity. In keeping with these goals I would also like to avoid using any mocking frameworks. Basically I want to do something like this:

request = APIRequestFactory().post(…)
view = MyViewSet.as_view(actions={"post": "create"})
self.assertTrue(MyPermission().has_permission(request, view))

The problem with this approach is that view is not actually a View instance but rather a function which does something with a View instance, and it does not have certain properties which I use in has_permission , such as action . How do I construct the kind of View instance which can be passed to has_permission ?

The permission is already tested at both the integration and acceptance level, but I would like to avoid creating several complex and time-consuming tests to simply check that each of the relevant actions are protected.

I've been able to work around this by monkeypatching a view set instance and manually dispatching it:

view_set = MyViewSet()
view_set.action_map = {"post": "create"}
view_set.dispatch(request)

You can do something like below.

request = APIRequestFactory().post(…)
view_obj = MyViewSet()
self.assertTrue(MyPermission().has_permission(request, view_obj))
