Simple DJANGO rest api test

test_core.py

import json
from rest_framework.test import APIClient
class TestClass():
  def setUp():
    self.client = APIClient()
    self.register_url=reverse('authentication:register')
  def test_create_user(self):
        """Tests if a user can create an account"""
        valid_register_data = {
        'user': {
        'email': '[email protected]',
        'username': 'aquaman',
        'password': 'testpass!XY'
         }

                response = self.client.post(self.register_url,
                                    data=json.dumps(
                                        valid_register_data),
                                    content_type='application/json')
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)

The test above uses API client built into django's restframework to test if a user can create an account successfully.
