Open Stack

Can someone tell me or point me to documentation about what the  
required yum and pip packages are to be able to run tox for glance,  
keystone, neutron, cinder and nova on Centos 6.5 with Python 2.6?  I  
looked at the openstack-infra/puppet-jenkins project and thought I  
installed everything in the slave.pp manifest, which presumably is  
sufficient to be able to run tox for all openstack projects, but when  
I try to run tox on nova (tox --recreate -epy26) I just get an error  
that indicates that no test cases were found.

Any help would be greatly appreciated.
