[Answer]-Login user by User object in django

I couldn’t find a clean way to login a user without a password: the only way suggested overloading the test client. At the end of the day, I wrote a decorator which creates an admin user and logs the user in.

from functools import wraps
from django.contrib.auth.models import User

from faker import Faker


def create_admin_user_and_login(func):                                                                                                                                                                       
    @wraps(func)
    def wrapper(self):
        faker = Faker()
        username = faker.pronounceable_unique_id(length=30)
        password = faker.password()
        user = User.objects.create_user(
            username=username,
            first_name=faker.word().title(),
            last_name=faker.word().title(),
            email=faker.email(),
            password=password)
        user.is_staff = True
        user.is_superuser = True
        user.save()
        self.client.login(username=username, password=password)
        return func(self)
    return wrapper

Where faker.faker.Faker is a class which generates some fake data.
