FYI for DefCore folks that might wish to contribute to the discussion as there are ~118 negative tests included in the most recent Board-approved DefCore Guideline.  [1]

We discussed negative tests included in the DefCore Guidelines a bit in the past and general consensus has been that it’s reasonable to include negative tests for a Capability since it validates that the “unhappy path” works in an interoperable way just as the “happy path” for an action does.  Note that the suggestion here is to move negative tests to the Tempest plugin interface.  As we’ve discussed, DefCore can accept in-project-tree tests via the Tempest plugin interface and RefStack will able to run them.  Therefore I think if this plan is implemented, it should be mostly non-impacting for us: we can continue including the negative tests we have today, though we may need to do some housekeeping as tests move around (so we should probably keep an eye on the review queues…it would be super helpful to have a heads-up from reviewers on those patches if possible, but we’ll probably find them either way =).

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