Patterns or Insights

The test consistently fails with the message "Expected pod \"testpod2\" in namespace \"e2e-pod-resize-scheduler-tests-...\" to be in phase Pending, but got phase: Running". This indicates an issue where the pod is not entering the expected 'Pending' phase, but rather immediately transitioning to 'Running'. This suggests a problem with the pod's lifecycle management or the scheduler's interaction with it, specifically related to the InPlacePodVerticalScaling feature. In all observed failures, this test appears to be the primary failing test, suggesting a specific issue with the test or the feature it validates rather than a systemic cluster problem.
