python - Django REST API TestCase Normalize Email failing

Question

I keep failing a test case that tests whether the email passed into the create_user function is normalized correctly. However the normalize_email() method does not seem to be working properly.

test_modles.py

from django.test import TestCase
from django.contrib.auth import get_user_model


    class ModelTests(TestCase):
    
        def test_new_user_email_normalized(self):
            """Test the email for a new user is normalized"""
            email = 'TEST.TES.com'
            user = get_user_model().objects.create_user(
                email,
                'test1213'
            )
    
            self.assertEqual(user.email, email.lower())

models.py

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, 
                                        PermissionsMixin


class UserManager(BaseUserManager):

    def create_user(self, email, password=None, **extra_fields):
        """Creates and saves a new user"""

        user = self.model(email=self.normalize_email(email), **extra_fields)
        user.set_password(password)
        user.save(using=self._db)

        return user

class User(AbstractBaseUser, PermissionsMixin):
    """Custome user model that supports using email instead of username"""
    email = models.EmailField(max_length=255, unique=True)
    name = models.CharField(max_length=255)
    is_active = models.BooleanField(default=True)
    is_teamMember = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)

    objects = UserManager()

    USERNAME_FIELD = 'email'

error

Answer 1

Found the error

def test_new_user_email_normalized(self):
            """Test the email for a new user is normalized"""
            email = 'TEST.TES.com' #<------------ Error Here -------
            user = get_user_model().objects.create_user(
                email,
                'test1213'
            )

should be

email = '[email protected]'
