Python, Django 단위 테스트. RequestFactory 테스트가 작동하지 않습니다.

테스트하고 싶은 뷰가 있습니다.

def change_item(request):
    name_change = request.POST.get('name_change')
    cost_change = request.POST.get('cost_change')
    category_change = request.POST.get('category_change')
    product_id = request.POST.get('product_id')
    category_name = Category.objects.get(name = category_change)
    product = Product.objects.get(id__exact = product_id)
    product.name = name_change
    product.category = category_name
    product.price = cost_change
    product.save()
    return HttpResponse()

테스트를 작성했는데 안 돼요 (요청 테스트하고 싶어요)

from django.test import RequestFactory
from django.test import TestCase
from views import change_item
from models import Product
from django.utils import unittest


class TestChange_item(TestCase):
    def setUp(self):
        self.factory = RequestFactory()

    def change_item_test(self):
        # Create an instance of a GET request.
        request = self.factory.get('main/views')
        # Test my_view() as if it were deployed at /customer/details
        response = change_item(request)
        self.assertEqual(response.status_code, 200)

실행하면 콘솔에 표시됩니다.

그것으로 무엇을 할 수 있습니까? 아니면 요청을 테스트하는 다른 방법이 있습니까?
