Summary

Adds a focused fixture-cluster E2E for the released operator-controller v1.11.0 migration handoff.

The migration tool creates revision 1 with collision protection None and waits for it to succeed. Creating the ClusterExtension then produces the controller-owned, catalog-derived revision 2 with collision protection Prevent. The test requires both revisions to reach Succeeded=True.

Fixture setup removes the installer-provided external operatorhubio ClusterCatalog, so catalog resolution is restricted to the committed local fixture catalog. Failures collect diagnostics under artifacts/e2e/cos-supersession.

Validation

  • E2E_KEEP_RESOURCES=true make migration/test-e2e-cos-supersession
  • make migration/test-unit

Summary by CodeRabbit

  • Bug Fixes

    • Updated migration-managed ClusterObjectSets to use migration-specific collision protection, reducing unintended adoption of existing resources.
    • Improved ClusterObjectSet supersession behavior so catalog-owned resources can correctly take over after migration.
  • Tests

    • Added an opt-in end-to-end test covering ClusterObjectSet supersession and revision handoff.
    • Added focused migration test tooling with optional resource retention for troubleshooting.

📝 Walkthrough

Walkthrough

Migration-generated ClusterObjectSets now disable collision protection. The change adds opt-in supersession E2E coverage, focused execution with cleanup control, fixture catalog cleanup, and a CI job with teardown and diagnostics.

Changes

ClusterObjectSet supersession

Layer / File(s) Summary
Migration collision protection policy
migration/pkg/migration/migration.go, migration/pkg/migration/phase.go, migration/pkg/migration/unit_test.go
Migration-generated ClusterObjectSets and phases now use CollisionProtectionNone. The unit test checks the updated value.
Supersession end-to-end test
test/e2e/migration/e2e_test.go
An opt-in test creates a migration ClusterObjectSet, installs a ClusterExtension, and verifies catalog-owned supersession, revisions, ownership, conditions, and collision protection.
Focused E2E execution and fixture setup
migration.mk, hack/e2e/migration/build-fixture-catalog.sh, .github/workflows/migration-test.yaml
The focused target controls cleanup with E2E_KEEP_RESOURCES. Fixture setup removes both catalog variants. CI runs the test, tears down the cluster, and uploads diagnostics when available.

A failed focused migration test leaves fixture resources behind unless retention is explicitly enabled. Capture the test status, clean up, then return that status before merging.

In `@test/e2e/migration/e2e_test.go`:
- Around line 202-315: The post-CreateClusterExtension assertions in
TestPrecreatedClusterObjectSetSupersession should verify adoption rather than
duplicate revision creation: require exactly one ClusterObjectSet, confirm its
UID equals precreatedUID, and remove the revision-1/revision-2 and catalog-COS
assertions. Preserve checks that the adopted COS has the expected migration
collision protection and reaches Succeeded=True.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Run cleanup after a failed test.

set -e exits when go test fails. The shell does not reach the E2E_KEEP_RESOURCES branch. A failed local run therefore retains migration resources even when E2E_KEEP_RESOURCES is false.

Capture the test exit status, run cleanup when retention is disabled, then return the captured status.
