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.

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): 
    def post_drone_category(self, name): 
        url = reverse(views.DroneCategoryList.name) 
        data = {'name': name} 
        response = self.client.post(url, data, format='json') 
        return response
