Writing the first round of unit tests

Now, we will write the first round of unit tests. Specifically, we will write unit tests related to the ESRB rating class-based views: EsrbRatingList and EsrbRatingDetail.

import pytest 
from django.urls import reverse 
from django.utils.http import urlencode 
from rest_framework import status

def create_esrb_rating(client, description): 
    url = reverse(views.EsrbRatingList.name) 
    esrb_rating_data = {'description': description} 
    esrb_rating_response = client.post(url...
