I have been writing tests for one of my django applications and have been looking to get around this problem for quite some time now. I have a view that sends messages using
I had the same problem when using a 3rd party app.
If you want to get the messages from a view that returns an HttpResponseRedict (from which you can't access the context) from within another view, you can use get_messages(request)
from django.contrib.messages import get_messages
storage = get_messages(request)
for message in storage:
do_something_with_the_message(message)
This clears the message storage though, so if you want to access the messages from a template later on, add:
storage.used = False
