Django POST Method Unit Test failing with Assertionerror 401

I am writing django unittests for an application which is having modules with HTTP get,put and post methods. I have been referencing rest_framework's APITestCase method for writing unittest for POST method.

Here is my code for POST method unittest:

def test_postByTestCase(self):
    url = reverse('lib:ingredient-detail',args=('123',))
    data = {'name':'test_data','status':'draft','config':'null'}
    response = self.client.post(url, data, format='json')
    self.assertEqual(response.status_code, status.HTTP_201_CREATED)

By running this test case I am getting this output:

$ python manage.py test lib.IngredientTestCase.test_postByTestCase

FDestroying test database for alias 'default'...

======================================================================

FAIL: test_postByTestCase (lib.tests.IngredientTestCase)

Traceback (most recent call last): File "C:\Apache2\htdocs\iLab\api\lib\tests.py", line 42, in test_postByTestCase self.assertEqual(response.status_code, status.HTTP_201_CREATED) AssertionError: 401 != 201

Ran 1 test in 5.937s

FAILED (failures=1)

I have tried passing HTTP_AUTHORIZATION token value, but it is not helping.

A 401 error means that your request is unauthorized. Does the application that you're trying to test require a login? If this is the case, you'll need to set up an authenticated user in your test before trying the POST request.

# my_api_test.py

def setUp:
    # Set up user
    self.user = User(email="[email protected]") # NB: You could also use a factory for this
    password = 'some_password'
    self.user.set_password(password)
    self.user.save()

    # Authenticate client with user
    self.client = Client()
    self.client.login(email=self.user.email, password=password)

def test_postByTestCase(self):
    url = reverse('lib:ingredient-detail',args=('123',))
    data = {'name':'test_data','status':'draft','config':'null'}
    response = self.client.post(url, data, format='json')
    self.assertEqual(response.status_code, status.HTTP_201_CREATED)

Once you've logged in a user to your client, then you should be able to call your API correctly and see a 201 response.
