Open Stack

I deployed a single node devstack on Ubuntu 14.04.
This devstack belongs to Juno.
I have written a cinder-volume driver for my client backend.
I want to contribute this driver in Juno release.
As i analyzed the contribution process,it is telling to run tempest tests
for Continuous Integration.

Could any one tell me how and which tempest tests to run on this devstack
deployment for cinder volume driver?
Also tempest has many test cases.Do i have to pass all tests for
contribution of my driver?

Also am i missing any thing thing in below local.conf?

*Below are steps for my devstack deployment:*

1) git clone https://github.com/openstack-dev/devstack.git
2)cd devstack
3)vi local.conf
