how i can test views py django - django

Question

i just learning how to pytest my code in django, and i need your help. So, i have tested my forms.py already,and now i want to test my views.py. I know that i need to test is it post on page,like by response on by ORM, but i cant understand how to do that, probably with my factories or no?
This is my views.py
class AddPost(CreateView):
model = Posts
form_class = PostsForm
template_name = 'posts/addpost.html'
success_url = '/'
def form_valid(self, form):
instance = form.save(commit=False)
if self.request.user.is_authenticated:
instance.owner = self.request.user
instance.save()
return HttpResponseRedirect(self.get_success_url())
class ShowPost(ListView):
model = Posts
template_name = 'posts/allposts.html'
paginate_by = 2
this is test_forms
#pytest.mark.django_db(True)
class TestPostCreationForm:
def test_form(self):
proto_post = PostsFactory.build()
form_payload = {
'phone_number': proto_post.phone_number,
'title': proto_post.title,
'type': proto_post.type,
'text': proto_post.text,
'price': proto_post.price,
'status': proto_post.status,
'image': proto_post.image,
}
form = PostsForm(form_payload)
assert form.is_valid()
instance = form.save()
assert instance.phone_number == proto_post.phone_number
assert instance.title == proto_post.title
assert instance.price == proto_post.price
and factories
from users.tests.factories import UserFactory
def get_mock_img(name='test.png', ext='png', size=(50, 50), color=(256, 0, 0)):
file_obj = BytesIO()
image = Image.new("RGB", size=size, color=color)
image.save(file_obj, ext)
file_obj.seek(0)
return File(file_obj, name=name)
class PostsFactory(factory.DjangoModelFactory):
owner = SubFactory(UserFactory)
phone_number = factory.Faker("phone_number", locale='uk_UA')
title = factory.fuzzy.FuzzyText(length=50)
text = factory.fuzzy.FuzzyText(length=250)
price = factory.fuzzy.FuzzyDecimal(10.5, 50.5)
status = factory.fuzzy.FuzzyChoice(choices=['active', 'deactivated'])
type = factory.fuzzy.FuzzyChoice(choices=['private', 'business'])
image = get_mock_img()
class Meta:
model = 'posts.Posts'

Use the Django test client. Although I don't use pytest, so I can't be certain that it's completely separable from the Django test runner which I use. I'd be surprised if that was not the case
Typical usage (POST to a simple form, which is expected to succeed and redirect)
data = {
"number_per_gridbox": "10",
"submit": "Submit" }
url_fill_gridbox = reverse( "jobs:qa_break_into_gridboxes",
kwargs={'jobline': self.jobline.pk ,'stockline': self.stockline.pk})
response = self.client.post( url_gridbox, data)
self.assertRedirects( response, url_fill_gridbox)
where you are testing error responses or GET, you can obtain the rendered HTML with
body = response.content.decode()
and you can look at entities in the context data that was used for rendering:
form_errors = response.context['form'].errors
As for setting up some objects for the view to process, you can either just create and save them with code (often in the setUp method), or you can use faker and factory-boy
