Hi

I have one proposal[1] related to negative tests in Tempest, and
hoping opinions before doing that.

Now Tempest contains negative tests and sometimes patches are being
posted for adding more negative tests, but I'd like to propose
removing them from Tempest instead.

Negative tests verify surfaces of REST APIs for each component without
any integrations between components. That doesn't seem integration
tests which are scope of Tempest.
In addition, we need to spend the test operating time on different
component's gate if adding negative tests into Tempest. For example,
we are operating negative tests of Keystone and more
components on the gate of Nova. That is meaningless, so we need to
avoid more negative tests into Tempest now.

If wanting to add negative tests, it is a nice option to implement
these tests on each component repo with Tempest plugin interface. We
can avoid operating negative tests on different component gates and
each component team can decide what negative tests are valuable on the
gate.

In long term, all negative tests will be migrated into each component
repo with Tempest plugin interface. We will be able to operate
valuable negative tests only on each gate.

Any thoughts?

Thanks
Ken Ohmichi
