TDD Django unittest to check the type of a context, like Queryset, List Class, so on.

test_type_of_context.py

from django.test import TestCase
# Is necessary import <class 'django.db.models.query.QuerySet'> to make this validation
from django.db.models.query import QuerySet

class UserTestCase(TestCase):
    def setUp(self)
      # (your setUp code here...)
      self.create_models()
  
    def create_models(self):
      # (your models code here...)
      
    def test_ix_view(self):
      # (some tests case here ...)
      # To validated if context is equal QuerySet, compare if the type of context is equal Django QuerySet Class.
      # type(self.response.context['queryset_context']) == <class 'django.db.models.query.QuerySet'>
      self.assertIs(type(self.response.context['queryset_context']), QuerySet) # This will return True
      self.assertEqual(len(self.response.context['queryset_context']), 2)
      
      
      # The same idea can be used to another types, like it:
      # type(self.response.context['list_context']) == <class 'list'>
      self.assertIs(type(self.response.context['list_context']), list) # This will return True
      self.assertEqual(len(self.response.context['list_context']), 1)
