Assert when ObjectDoesNotExitst is raise [duplicate]

Question

I have this function which raises the ObjectDoesNotExist

def is_user_login(self,id):
    try:
        u = m.CustomUser.objects.get(id=id)
    except ObjectDoesNotExist as e:
        raise e

Now I am writing the test script.

    try:
        CommonFunc.is_user_login(4)
    except Exception as e:
        print(e)
        self.assertEqual(ObjectDoesNotExist,e)

It doesn't work.

It shows error like this below ,

AssertionError: <class 'django.core.exceptions.ObjectDoesNotExist'> != DoesNotExist('CustomUser matching query does not exist.')

How can I assert for ObjectDoesNotEqual?

Answer 1

This is normally done with an .assertRaises(…) ^[Python-doc] context processor:

with self.assertRaises(ObjectDoesNotExist):
    CommonFunc.is_user_login(4)

However re-raising the exception however does not seem to make much sense, why not:

def is_user_login(self, id):
    # no try
    u = m.CustomUser.objects.get(id=id)
