Writing a first round of unit tests

Now, we will write the first round of unit tests. Specifically, we will write unit tests related to the game category class-based views: GameCategoryList and GameCategoryDetail. Open the existing games/test.py file and replace the existing code with the following lines that declare many import statements and the GameCategoryTests class. The code file for the sample is included in the restful_python_chapter_04_04 folder, as shown:

from django.test import TestCase 
from django.core.urlresolvers import reverse 
from django.utils.http import urlencode 
from rest_framework import status 
from rest_framework.test import APITestCase 
from games.models import GameCategory 
 
 
class GameCategoryTests(APITestCase): 
    def create_game_category(self, name): 
        url = reverse('gamecategory-list') 
        data = {'name': name} 
        response = self.client.post(url, data, format='json') 
        return response 
 
    def test_create_and_retrieve_game_category...
