Idea:

I love this plan already.<br>

- Tempest gate will keep running all the services tests as the integrated gate at a centeralized place without any change in the current job.
- Each project can run the below mentioned template.
- All below template will be defined and maintained by QA team. </pre>

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

I would like to know each 6 services which run integrated-gate jobs
1."Integrated-gate-networking" (job to run on neutron gate)
Tests to run in this template: neutron APIs , nova APIs, keystone APIs ? All scenario currently running in tempest-full in the same way ( means non-slow and in serial)
Improvement for neutron gate: exlcude the cinder API tests, glance API tests, swift API tests,
2."Integrated-gate-storage" (job to run on cinder gate, glance gate)
Tests to run in this template: Cinder APIs , Glance APIs, Swift APIs, Nova APIs and All scenario currently running in tempest-full in the same way ( means non-slow and in serial)
Improvement for cinder, glance gate: excluded the neutron APIs tests, Keystone APIs tests
3. "Integrated-gate-object-storage" (job to run on swift gate)
Tests to run in this template: Cinder APIs , Glance APIs, Swift APIs and All scenario currently running in tempest-full in the same way ( means non-slow and in serial)
Improvement for swift gate: excluded the neutron APIs tests, - Keystone APIs tests, - Nova APIs tests.</pre>

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.<br>

<p>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
<a class="moz-txt-link-freetext" href="https://review.opendev.org/#/c/601813/">https://review.opendev.org/#/c/601813/</a> . 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
feedback loops.</p>
<p>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.<br>

4. "Integrated-gate-compute" (job to run on Nova gate)
tests to run is : Nova APIs, Cinder APIs , Glance APIs ?, neutron APIs and All scenario currently running in tempest-full in same way ( means non-slow and in serial)
Improvement for Nova gate: excluded the swift APIs tests(not running in current job but in future, it might), Keystone API tests.
5. "Integrated-gate-identity" (job to run on keystone gate)
Tests to run is : all as all project use keystone, we might need to run all tests as it is running in integrated-gate.
But does keystone is being unsed differently by all services? if no then, is it enough to run only single service tests say Nova or neutron ?
6. "Integrated-gate-placement" (job to run on placement gate)
Tests to run in this template: Nova APIs tests, Neutron APIs tests + scenario tests + any new service depends on placement APIs
Improvement for placement gate: excluded the glance APIs tests, cinder APIs tests, swift APIs tests, keystone APIs tests
Thoughts on this approach?
The important point is we must not lose the coverage of integrated testing per project. So I would like to
get each project view if we are missing any dependency (proposed tests removal) in above proposed templates.</pre>
</blockquote>
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.<br>
