Right. The point of having the trademark tests "in tempest" was not
to have them "in the tempest repo", that was just an implementation
detail of the policy of "put them in a repository managed by people
who understand the expanded review rules".
There were a lot of unexpected issues when we started treating the
test suite as a production tool for validating a cloud. We have
to be careful about how we change the behavior of tests, for example,
even if the API responses are expected to be the same. It's not
fair to vendors or operators who get trademark approval with one
release to have significant changes in behavior in the exact same
tests for the next release.
At the early stage, when the DefCore team was still figuring out
these issues, it made sense to put all of the tests in one place
with a review team that was actively participating in establishing
the process. If we better understand the "rules" for these tests
now, we can document them and distribute the work of maintaining the
And yes, I agree with the argument that we should be fair and treat
all projects the same way. If we're going to move tests out of the
tempest repository, we should move all of them. The QA team can
still help maintain the test suites for whatever projects they want,
even if those tests are in plugins.
