[Deepsea-users] Teuthology is not for unit testing

Sorry I was not subscribed until just now.
Let me say I heartily agree with the general direction of Ricardo's
proposal, i.e. that automated PR validation testing is desirable/needed.
Jan makes a good point that any meaningful testing of DeepSea requires
that a Ceph cluster be deployed.
Right now, DeepSea expects that cluster to be on a certain minimum
number of nodes?
I know it's possible to run a Ceph cluster on a single node. Can DeepSea
do that kind of deployment right now? If not, what kind of modifications
would be needed?
(The ability to deploy one- and two-node clusters would be useful for
DeepSea to have, since many teuthology test cases are designed to run on
such minimal configurations.)
If the whole thing could run on a single VM, that (in my mind) would
satisfy the definition of a unit test suite.
When Jenkins is triggered on a PR, it would create a VM in OpenStack,
git clone the branch/SHA1, run the test suite, get the result, and then
destroy the VM. The Jenkins machine could also be a VM in OpenStack.
Teuthology could be used as well, but not without significant
modifications. In my mind, unit testing should be kept as simple and
light-weight as possible. Teuthology does not fit into that mould.
