Here is small sum of frameworks/tools to give you an idea what we are
currently using to test RHOS components.

To create Triple-O undercloud/overcloud we are using the:

https://github.com/redhat-openstack/ansible-ovb

And then to install RHOSP on existing Triple-O:

https://github.com/redhat-openstack/ansible-rhosp

Then to run CI in such environment we use octario which is our main tool to
run different flavors of tests and it's separate CI tool to be ready with
different provisioning frameworks.

https://github.com/redhat-openstack/octario/


In the simplistic environment to run simple tests we are using InfraRed to
provision simple instance (without Triple-O):

https://github.com/rhosqeauto/InfraRed

And then we run octario in such environment to run actual tests.

Ideally if the provisioning parts were common and we could reuse them.
Currently we need to use yet another set of tools to be able to patch rpm's
prior to running tests.

There was an idea planted by dsariel to move some of the playbooks into
ansible-galaxy roles (possibly other teams had such idea as well), which I
can see it's another +1 for going with tools currently developed by Wes as
they are pretty separate and could be converted into ansible-galaxy, to be
available across different use-cases, but then it would need to be well
defined so the roles are not multiplied and we won't end up having similar
roles.
