The controller may update BootcNode metadata while envtest simulates a daemon status update. Both operations advance resourceVersion, making a single Get followed by Status().Update susceptible to conflicts. Use client-go RetryOnConflict so the simulated daemon refetches the latest BootcNode before retrying its status update. Assisted-by: AI Signed-off-by: HarshwardhanPatil07 <harshpat@redhat.com>
Users currently need to inspect conditions and controller logs to understand image resolution, rollout progress, node transitions, and blocked drains. Emit Kubernetes Events for these meaningful observations without using Event delivery to drive reconciliation. Reuse the existing image resolution and drain state paths, persist node transition bookkeeping in a controller-owned annotation, and bound Event notes to the events.k8s.io 1 KiB limit. Grant the recorder create and patch access to both supported Event API groups. Related: bootc-dev#101 Assisted-by: AI Signed-off-by: HarshwardhanPatil07 <harshpat@redhat.com>
Exercise pool, node, and drain Event behavior with exact reason, action, relationship, and note assertions. Cover transition deduplication, annotation write failures, tag resolution, degraded status, drain scheduling, and UTF-8-safe note truncation. Use envtest Event objects filtered by regarding UID so retained Events from an earlier object with the same name cannot satisfy the integration assertions.

Envtest does not exercise the deployed RBAC, Event broadcaster, daemon, or real reboot path. Extend the existing bink update and tag-resolution scenarios to assert the Events produced by a deployed operator. Filter Events by the regarding object UID and verify exact types, reasons, actions, notes, and related pool identity.

There was a problem hiding this comment.
we can have this as helper func something like
func FilterEventsByObject(items []eventsv1.Event, kind, name string, uid types.UID) []eventsv1.Event {
out := make([]eventsv1.Event, 0, len(items))
for _, e := range items {
if e.Regarding.Kind == kind && e.Regarding.Name == name && e.Regarding.UID == uid {
out = append(out, e)
}
}
return out
}

we can have this store in var observation + ":" + node.Spec.DesiredImage
