I'm trying to write some unit tests on a Django (I'm using Django==1.9.12) application that uses django-tls, but I always get this exception: RuntimeError: no object bound to request. My code looks like this:
settings.py:
As in django-tls doc I added the line 'tls.TLSRequestMiddleware' to my MIDDLEWARE_CLASSES:
MIDDLEWARE_CLASSES = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'tls.TLSRequestMiddleware',
]
I wrote a method to test it on a module called utils.py:
from tls import request
def print_tls_found_by_django_tls():
"""
Just print the request instance found by django-tls.
:return:
"""
print(request)
On my test_utils.py I have tried to follow the Werkzeug test utilities because Werkzeug is what django-tls uses to discover the request instance. So I coded something like this for testing that:
from werkzeug.test import EnvironBuilder
from django.test import TestCase
from example_app.utils import print_tls_found_by_django_tls
class TestUtils(TestCase):
def setUp(self):
self.build_tls_request()
def test_print_tls_found_by_django_tls(self):
print_tls_found_by_django_tls()
def build_tls_request(self):
return EnvironBuilder(method='GET').get_request()
but then the exception is there:
(venv) vladir@vladir:~/work/project_example_all/example/example_app$ coverage run ./manage.py test example_app.tests.TestUtils.test_print_tls_found_by_django_tls

I would appreciate any help or clue you could give me to find a solution to this. I have tried several things but without any luck. Thanks in advance mates.
