[Twisted-Python] Stopping Reactor in UnitTest Callback

[Fabian Rothfuchs]

I'm in the dilemma of using both - Django and Twisted.
My goal is to have Django initialising the test (python manage.py test
<appname>), instead of trial, as it will setup the whole test environment
(I.e. Creates a db copy, allows per-model testing, follows certain
conventions, etc).

As to that I'm trying to find a way how to start/stop the reactor from the
test, as trial is not executed.
Do you have an idea or an approach how this could be realised?

Thanks
Fabian
