Writing unit tests for a RESTful Web Service

Now, we will write our first round of unit tests related to the drone category class based views: DroneCategoryList and DroneCategoryDetail. Open the existing restful01/drones/tests.py file and replace the existing code with the following lines that declare many import statements and the DroneCategoryTests class.

from django.utils.http import urlencode 
from django.core.urlresolvers import reverse 
from rest_framework import status 
from rest_framework.test import APITestCase 
from drones.models import DroneCategory 
from drones import views 
 
 
class DroneCategoryTests(APITestCase):
