Testing the Custom User Model

Testing is a critical part of software development. This section will cover how to effectively test your custom User model to ensure it behaves as expected across various scenarios.

1. Setting Up Tests

To begin testing, create a new test case in your Django app’s tests.py file:

from django.test import TestCase
from .models import CustomUser

class CustomUserModelTests(TestCase):
    def setUp(self):
        self.user = CustomUser.objects.create_user(
            username='testuser',
            password='testpassword',
            email='test@example.com'
        )

2. Testing User Creation

Write tests to verify that users can be created successfully and that their attributes are set correctly:

    def test_user_creation(self):
        self.assertEqual(self.user.username, 'testuser')
        self.assertTrue(self.user.check_password('testpassword'))

3. Testing Superuser Creation

Test the creation of a superuser to ensure it has the correct permissions:

    def test_create_superuser(self):
        superuser = CustomUser.objects.create_superuser(
            username='superuser',
            password='superpassword',
            email='super@example.com'
        )
        self.assertTrue(superuser.is_superuser)
        self.assertTrue(superuser.is_staff)

4. Testing Authentication

Ensure that authentication functions correctly with your custom User model:

    def test_authentication(self):
        user = CustomUser.objects.get(username='testuser')
        self.assertTrue(user.check_password('testpassword'))

5. Running the Tests

To execute the tests, use the following command:

python manage.py test yourapp

Best Practices

Maintain thorough and comprehensive tests to cover all functionalities related to your custom User model. Regularly run tests after making changes to ensure everything remains functional.
