I'm trying to setup openstack nova dev environment. I've successfully installed devstack from the trunk and played around. However, I cannot get run_tests.sh to execute to completion.

Steps I followed:

Installed Ubuntu 12.04 
git clone https:/github.com/openstack/nova.git 
cd nova; run_tests.sh
 

I get the following error:

tools/with_venv.sh: line 13: testr: command not found 

Any idea how/where can I get testr? testr seems like bash function more so than a command.

Any help appreciated! Thanks, -Jay
