Hi @MIBc. Thanks for your PR.

I'm waiting for a knative 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.

Thanks. This looks reasonable.
Can you also check that PanicM is set and unset.

}

this is the same as the method above just with different argument names and order

I have combined these two tests and added PanicM.

I meant expectedEBC is an existing method. This method you wrote is a duplicate and can be removed.

a.expectScale(t, time.Now(), 5, expectedEBC(10, 100, 50, 1), true)
spec, podCounter := a.currentSpecAndPC()
originalReadyPodsCount, _ := podCounter.ReadyCount()
wantTags := map[string]string{}

Shouldn't the tags be non-empty?
I think we create the autoscaler with empty context, but for this test we probably want a one with tags set to make sure we use the correct one.
