Trouble using django.template Context in unittest

I got a little confusing situation here when I use the Context from django.template. The following works in the python shell: ``` >>> from django.template import Context, Template >>> b=Template('TEST').render(Context()) >>> print b TEST ``` When I use the very same Code in a unittest, I get the follwing Error: ``` Traceback (most recent call last): File "/newsletterapi/tests.py", line 25, in setUp b = Template('TEST').render(Context()) File "/opt/python2.7/lib/python2.7/site-packages/django/template/base.py", line 121, in render context.render_context.push() AttributeError: 'Context' object has no attribute 'render_context' ``` The unittest looks like this: ``` from django.test import TestCase from myproject.newsletterapi.models import Newsletter from django.utils.termcolors import colorize from django.db import IntegrityError from django.template import Template, Context import random import datetime from decimal import * import string class NewsletterTest(TestCase): def setUp(self): b = Template('TEST').render(Context()) # this is line 25 self.newsletter = Newsletter(body=b) self.newsletter.save() ### ... continues here ``` Does anyone have an idea why this works in the shell but not in the unittest? I appreciate every hint.
