Testing Multiple inheritance CBV in Django leads to redundant tests

I have a base view that is defined as following:

class EditProfileMixin(LoginRequiredMixin, UpdateView):
    def get_object(self, *args, **kwargs):
        return self.request.user

I am inheriting from this view for any action that requires user to be logged in to update any private information ( contact details etc.), and test those views for the same functionality ( user is logged in and get_object returns the right information.

however , I feel that I am doing it wrong because the tests seems redundant to me ... what is the right way of testing this kind of inheritance ?
