I am using *django_webtest* to test my views and *django_nose_selenium* to test the ajax on my site ( I could not get webtest.sel working + static files were not served since debug=False when running unit tests).
I am running the full test suite using
./manage.py test project --with-selenium --with-cherrypyliveserver and keep getting erratic behavior between django_webtest and the selenium tests.
It seems like when I have an odd number of django webtest, the suite passes - when it's an even number, I get SAVEPOINT can only be used in transaction blocks exceptions ( see stack below). I discovered that by adding a simple test case ( assertTrue(2 == 1+1).
Could this be related to the cherrypy server settings? Any thoughts on what might be going on? What combination of tools do you use to test your views + ajax?

I'm using webtest.sel without problem. Just add some stuff to serve your static files if you're in a test
Let say an env var:
Then in your urls.py:
