Package: python-testtools

Downgrading python-testtools to 0.9.39-2 - with no other changes - completely
fixes the problem.
This happens with all calls to the django unit tests using manage.py test.
ii python-django 1.7.10-1
To reproduce, it is necessary to install lava-server, so a Stretch VM is
recommended.
This provides the django environment and migrations:
$ echo "Accept defaults for debconf prompts"
$ sudo apt -y install lava-server lava-dev
$ git clone http://git.linaro.org/lava/lava-server.git
$ cd lava-server
$ git checkout release
$ ./ci-run -v2
To call unit tests individually, use:
$ ./lava_server/manage.py test <app_name>
where <app_name> is one of dashboard_app, lava_scheduler_app,
lava_scheduler_daemon or lava_results_app.

Version: 1.8.7-2
I was hasty and thought that 1.8.7-1 was the proposed fix.
I installed 1.8.7-2 from incoming.debian.org and 1.8.7-2 is much better
- as I suspected, there are failures in the unit tests which were being
hidden by this bug. Likely due to the long history of the codebase
where some of the transaction handling code dates from the days of
django1.2. This is where the new unit test failures are happening.
Thanks for this fix. It is python-testtools which is revealing these
unit test failures but I can now identify the fixes I need.
