Hi @astefanutti. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Is the issue also reflected in ClusterQueue.status? I believe it is. It would be much simpler to test for that and also we could cherry-pick to 0.5.
The visibility server doesn't exist in 0.5, so we can't cherry-pick it.

I think the bug is also impacting the eq.status.pendingWorkloads counter, so we could use this to verify the fix works at the level of integration tests.

You're right! I've removed the integration tests for the visibility API, and added a test case to the existing cluster queue controller integration tests, that verifies the fix.

I've kept it as minimal as possible this time, but feel free to suggest any other test cases that you think could be useful to add there.

Just non-blocking nits to improve readability of the test.

non-blocking nit: I would prefer to turn the comment into ginkgo step. Maybe ginkgo.By("await until the pending workload count is incremented as the workload is inadmissible, because the ResourceFlavors don't exist"). This way the comment is also logged, which can make debugging easier.

Agreed. Actually I saw an existing comment and somehow decided to choose that style, but I would have chosen the ginkgo.By stanza otherwise. Let me know if you feel like it's worth I open a follow-up PR.

I didn't notice the PR was approved actually, and thought you would have time to apply the remark.
I'm ok either way, as you feel.
