What to test? Where to get what to test? Where to report testing results?

At the time of writing those lines, i do not see any OpenQA entree either in the PR that was approved above, nor any new issue created under Issues · QubesOS/updates-status · GitHub

Edit: they were there.
Then PR got merged to xmm-xen.

@marmarek/@adw can you detail the flow of a an approved code PR → OpenQA testing output to look at (how are those linked outside of seeing pipelineretry) → signing → issue being created under Issues · QubesOS/updates-status · GitHub → package landing under unstable repositories to be testable ?
