I love this plan already.

My biggest regret is that I couldn't figure out how to do this myself.
Much thanks to the QA team!

This sounds great. My only question is why Cinder tests are still
included, but I trust that it's there for a reason and I'm just
revealing my own ignorance of Swift's consumers, however removed.

Correct, and for all the reasons that you're seeking to address. Some
eight months ago I'd gotten tired of seeing spurious failures that had
nothing to do with Swift, and I was hard pressed to find an instance
where the tempest tests caught a regression or behavior change that
wasn't already caught by Swift's own functional tests. In short, the
signal-to-noise ratio for those particular tests was low enough that a
failure only told me "you should leave a recheck comment," so I proposed
https://review.opendev.org/#/c/601813/ . There was also a side benefit
of having our longest-running job change from
legacy-tempest-dsvm-neutron-full (at 90-100 minutes) to
swift-probetests-centos-7 (at ~30 minutes), tightening developer
It sounds like this proposal addresses both concerns: by reducing the
scope of tests to what might actually exercise the Swift API (if
indirectly), the signal-to-noise ratio should be much better and the
wall-clock time will be reduced.

As far as Swift is aware, these dependencies seem accurate; at any rate,
*we* don't use anything other than Keystone, even by way of another API.
Further, Swift does not use particularly esoteric Keysonte APIs; I would
be OK with integrated-gate-identity not exercising Swift's API with the
assumption that some other (or indeed, almost *any* other) service would
likely exercise the parts that we care about.
