Тестирование Django: тест не работает при создании представления с запросом post

Я создаю тесты для своих представлений и не могу создать правильный тест для общего CreateView. В основном я следую этой документации: https://docs.djangoproject.com/pl/4.0/topics/testing/advanced/#django.test.RequestFactory. Есть ли у кого-нибудь решение для этого?

blog.models

class Post(models.Model):
    title = models.CharField(max_length=128)
    intro = models.TextField()
    content = models.TextField()
    date = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

    def get_absolute_url(self):
        return reverse('blog:post-detail', kwargs={'pk': self.pk})

    def __str__(self):
        return self.title

blog.views

class PostCreateView(LoginRequiredMixin, CreateView):
    model = Post
    fields = ['title', 'intro', 'content', 'category']

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

blog.urls

app_name = 'blog'
urlpatterns = [
    path('post/new/', views.PostCreateView.as_view(), name='post-create'),
    # some other paths,]

blog.tests.test_views

class PostViewsTests(TestCase):

    def setUp(self):

        self.author = User.objects.create_user(
            username='abcUser, 
            email='abcuser@mail.com',             
            password='abcpassword')
        self.category = Category.objects.create(name='New test category')
        self.new_post = Post.objects.create(
            title='Lorem Ipsum',
            intro='Neque porro quisquam est ',
            content='There is no one who loves pain itself...',
            author=self.author,
            category=self.category)

        self.client = Client()
        self.factory = RequestFactory()

def test_post_create_view_if_adds_new_post(self):
    data = {
        'title': 'Lorem Ipsum2',
        'intro': 'Neque porro quisquam...',
        'content': 'Neque porro quisquam... - There is no...',
        'category': self.category
    }
    request = self.factory.post(reverse('blog:post-create'), data=data)
    request.user = self.author
    response = views.PostCreateView.as_view()(request)

    newest_post = Post.objects.order_by('-date').first()

    self.assertEqual(response.status_code, 200)
    self.assertEqual(newest_post.title, 'Lorem Ipsum2')

результат теста:
