Django-Python Django Login test failed with factory_boy and Authtools

Question

My unit testings are failing when i want to test Login functionality. When I test in my browser is's OK.

I'm using:

django==1.6.5
factory-boy==2.4.1
WebTest==2.0.15
django-webtest==1.7.7
nose==1.3.3
django-nose==1.2

There are no custom user model. The user model is authtools.models.User.

My views:

from authtools.views import LoginView
from django.views.generic import TemplateView
from django.core.urlresolvers import reverse

class Home_view(LoginView):
    template_name = 'users/home.html'
    disallow_authenticated = False

    def get_success_url(self):
        return reverse('users:blob')


class Blob_view (TemplateView):
    template_name = "users/blob.html"

My factories:

import factory


from django.conf import settings
from django.contrib.auth.hashers import make_password

class UserFactory (factory.DjangoModelFactory):
    """
    Factory used to instanciate a :class: Users.User
    """

    class Meta:
        model = settings.AUTH_USER_MODEL

    name = factory.Sequence(lambda n: 'user%d' % n)
    email = factory.LazyAttribute(lambda obj: '%[email protected]' % obj.name)
    password = make_password('eCRD')
    is_active = True

My tests: There are two test. The first test the client login, the second test the views:

from django.core.urlresolvers import reverse


from django_webtest import WebTest
from authtools.models import User
from rest_framework import status


from .factories import UserFactory


class UserLoginTests(WebTest):

    def setUp(self):
        self.user = UserFactory()


    def tearDown(self):
        User.objects.get(email = self.user.email).delete()

    def test_user_login_client(self):
        self.resp = self.client.login(username = self.user.email, password = self.user.password
        )
        self.assertEqual(self.resp, True)
        self.client.logout()

    def test_user_logsin_view(self):
        Home_View = self.app.get(reverse('users_home'))
        Login_Form = Home_View.forms['login-form']
        Login_Form['username'] = self.user.email
        Login_Form['password'] = self.user.password
        response = Login_Form.submit().follow()
        self.assertEqual(redirect.status_code, status_HTTP_200_ok)
        self.client.logout() 

Both test failed. But in the browser it work well.

Thanks.

Answer 1

I answer myself. The solution is: Factory_boy under the hook calls model.objects.create(). When you create a user, the auth model calls model.objects.create_user(). Both work. But the difference is that create_user usees django.contrib.auth.hashers.make_password for password encryption and create saves the password as plain text. Then the solution is:

from django.core.urlresolvers import reverse


from django_webtest import WebTest
from authtools.models import User
from rest_framework import status


from .factories import UserFactory, user_password


class UserLoginTests(WebTest):

    def setUp(self):
        self.user = UserFactory()


    def tearDown(self):
        User.objects.get(email = self.user.email).delete()

    def test_user_login_client(self):
        self.resp = self.client.login(username = self.user.email, password = user_password
        )
        self.assertEqual(self.resp, True)
        self.client.logout()

    def test_user_logsin_view(self):
        Home_View = self.app.get(reverse('users_home'))
        Login_Form = Home_View.forms['login-form']
        Login_Form['username'] = self.user.email
        Login_Form['password'] = user_password
        response = Login_Form.submit().follow()
        self.assertEqual(redirect.status_code, status_HTTP_200_ok)
        self.client.logout() 

And the factories

import factory


from django.conf import settings
from django.contrib.auth.hashers import make_password

user_password = 'test'   # Testing password 

class UserFactory (factory.DjangoModelFactory):
    """
    Factory used to instanciate a :class: Users.User
    """

    class Meta:
        model = settings.AUTH_USER_MODEL

    name = factory.Sequence(lambda n: 'user%d' % n)
    email = factory.LazyAttribute(lambda obj: '%[email protected]' % obj.name)
    password = make_password(user_password)
    is_active = True
