// TODO: add tests that cover deployment.Spec.MinReadySeconds once we solved clock-skew issues
// See https://github.com/kubernetes/kubernetes/issues/29229
// Add UnavailableReplicas check because ReadyReplicas or UpdatedReplicas might not represent
// the actual number of pods running successfully if some pods failed to start after update or patch.
