IT Failure(google-cloud-compute): ITPaginationTest.testPaginationIterating zone not found #9134
Description

This could be a similar issue with interfering compute resources from integration tests as observed/addressed in #8260.

Update - seems like this is a previously observed flake coming back: googleapis/java-compute#683, googleapis/java-compute#682 (comment) look relevant.

An initial investigation from locally reproducing this error w/ Terraform:
gcloud compute zones listreturns 119 zones, which also consistent with theresponse.iterateAll()size from testList().In testPaginationIterating(), iterating over zones sometimes gets stuck at around this point:
response.IterateAll()size: 46And sometimes able to get a full list including

The nightly builds are back to green, and I am no longer able to reproduce this error 🤔. Leaving this issue open to track and revisit if it resurfaces again.

Closing this issue now. It's been ~3 months since this last flaked. We can re-open if this test flakes again.

Observed this flake again in nightly build - reopening to track.
