As you know, I'm up for this :) There is already a session accepted on
combining the existing functional/integration test suites:

http://summit.openstack.org/sessions/view/40

I propose we discuss your point #1 above in that session.

I certainly want to make sure that we are de-duplicating the work that
is being done by the various groups interested in testing and QA. That
was the impetus behind the OpenStack QA team and project on Launchpad
:) Where can we see this regression analysis framework? Is it up on
GitHub?

As for test automation and test environments (points 4 and 3 above),
we already have a Jenkins system for the automation piece:

https://jenkins.openstack.org/job/openstack-deploy-rax/
https://jenkins.openstack.org/job/openstack-test-rax/

along with a number of scripts and glue code for firing off
deployments into bare-metal clusters available here:

https://github.com/openstack/openstack-ci
https://github.com/openstack/openstack-puppet

We plan on introducing the ability for these scripts to pull in Chef
recipes instead of the Puppet modules it currently pulls from the
GitHub repo above.

Right now, the openstack-deploy-rax deploys an OpenStack system onto a
4-machine cluster, that is "wiped and reset" after each test run with
a snapshot image that can be quickly kexec'd. This is to avoid the
lengthy build times associated with having to fully PXE boot with
something like cobbler or Crowbar.

That said, we would not be opposed to having additional Jenkins
builders that tested the full deployment environment *including* the
deployment framework (Cobbler, Crowbar, Ensemble, whatever). But, we'd
need to secure hardware resources (bare-metal) in order to do this
testing properly.

I think from our team specifically, I would count on myself, Jim Blair
and Monty Taylor. I'm also pretty sure at least 4 folks from NTT
(Nati-san, Shida-san, Tushar Patil, Rohit Karajgi) will plan on
attending.

Looking forward to the discussions!
