There is an open ticket requesting this at https://github.com/rlisagor/freshen/issues/16I also attached a link to a github branch implementing this.
Something like this gives a little more info:
./manage.py test -- -v
There is a patch to improve thing like this on github and the author promised to merge it but it seems he didn't.
