I'm testing user's creation but the test haven't reach the failed test because of the error given TypeError: expected str, bytes or os.PathLike object, not NoneType.
I have the migrations using pass on using the AbstractUser giving the following on the migrations/0001initial.py file:
# Generated by Django 3.1.4 on 2021-07-12 15:00
import django.contrib.auth.models
import django.contrib.auth.validators
from django.db import migrations, models
import django.utils.timezone
class Migration(migrations.Migration):
initial = True
dependencies = [
('auth', '0012_alter_user_first_name_max_length'),
]
operations = [
migrations.CreateModel(
name='User',
fields=[

options={
'verbose_name': 'user',
'verbose_name_plural': 'users',
'abstract': False,
},
managers=[
('objects', django.contrib.auth.models.UserManager()),
],
),
]
The test case I'm using is the following:
from django.contrib.auth import get_user_model
from rest_framework import status
from rest_framework.reverse import reverse
from rest_framework.test import APITestCase
PASSWORD = 'pAssw0rd!'
class AuthenticationTest(APITestCase):
def test_user_can_sign_up(self):
response = self.client.post(reverse('sign_up'), data={
'username': 'user@example.com',
'first_name': 'Test',
'last_name': 'User',
'password1': PASSWORD,
'password2': PASSWORD,
})
user = get_user_model().objects.last()
self.assertEqual(status.HTTP_201_CREATED, response.status_code)
self.assertEqual(response.data['id'], user.id)
self.assertEqual(response.data['username'], user.username)
self.assertEqual(response.data['first_name'], user.first_name)
self.assertEqual(response.data['last_name'], user.last_name)
So when I run python manage.py test trips.tests, I'm getting the this traceback error:

Any idea why is it throwing this NoneType??

EDIT II:
I was missing the __init__py file inside the tests directory. But I'm still getting the same error with a different traceback:
