We don't really need a blueprint for this work. It would be good to know 
what gaps in existing testing you think exist. And where do you plan on 
implementing these tests? In the nova/tests/functional tree or somewhere 
else? We already have a lot of tests which are using a CellDatabase 
fixture which allow us to create multiple cell mappings for tests in the 
API.

If you're considering Tempest, tests there wouldn't really be 
appropriate because to the end user of the API, they should have no idea 
if they are talking to a cloud with multiple cells or not, since it's 
really a deployment issue.

What we don't have today in our CI testing, and that we need someone to 
work on, is running a devstack multi-node setup with at least two cells. 
This likely requires some work in the devstack-gate repo to configure 
devstack per node to tell it which cell it is.

I encourage you to bring this up in a weekly cells v2 meeting for 
further discussion:
