3051	django.test.client.Client() does not set HttpResponse context and template properly	anonymous	Adrian Holovaty	"Using a view function that relies upon render_to_response(template, context), I run a doctest over the view function utilizing the django.test.client.Client class, however when I get my response object back, the context and template attributes are None.

I thought it might be specific to the doctest, however running the test by hand in a python shell yields the same result.

My view:
{{{
