Merge the test from argocd-operator. Both the tests were written differently testing conceptually similar thing (creation of ConfigMap, ClusterRole and ClusterRoleBinding) in 2 different situations:

  • Having the namespace declared in ARGOCD_CLUSTER_CONFIG_NAMESPACES initially
  • Adding the namespace into ARGOCD_CLUSTER_CONFIG_NAMESPACES when Argo CD was running

📝 Summary

Summary by CodeRabbit

  • Tests
    • Expanded cluster configuration test coverage for the Argo CD application controller, server, and ApplicationSet controller, including their access resources and the namespace’s SSH known-hosts configuration.
    • Added coverage for configuring the namespace before creating an Argo CD instance and for adding it after creation. The latter scenario is skipped during local runs.

The end-to-end tests now share checks for controller ClusterRoles, ClusterRoleBindings, and the SSH known-hosts ConfigMap. They cover initial namespace configuration and adding a namespace after creating the Argo CD instance.

Changes: Cluster Configuration Tests

Layer / File(s) Summary
Shared cluster configuration checks
test/openshift/e2e/ginkgo/sequential/1-003_validate_cluster_config_test.go
A helper derives resource names for the application controller, server, and ApplicationSet controller. It checks their ClusterRoles and ClusterRoleBindings, plus the namespace’s SSH known-hosts ConfigMap.
Initial and updated namespace scenarios
test/openshift/e2e/ginkgo/sequential/1-003_validate_cluster_config_test.go
The tests create instances with ApplicationSet settings and check cluster configuration. The namespace-addition test starts with the test namespace excluded, then adds it before checking the resources.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to 6a80c

The tests can miss an ApplicationSet controller failure; restore the assertion before relying on this coverage.

Preserve live-update ApplicationSet RBAC coverage.

The existing status test covers enabling ApplicationSet after creation, but it only checks status Running. The replacement dynamic-namespace test configures ApplicationSet at creation, so it no longer checks whether a live update creates the ApplicationSet ClusterRole and ClusterRoleBinding. A regression in that path can pass.

Assert that the application-controller ClusterRole is absent before the update.

ARGOCD_CLUSTER_CONFIG_NAMESPACES excludes the test namespace before the update, so the application-controller ClusterRole should not exist at that point. The test only checks that the ClusterRole exists afterward. Without the negative assertion, a resource that existed before the update can satisfy the final check.

Preserve the ApplicationSet update path in the namespace-addition test.

The namespace-addition test now creates Spec.ApplicationSet before the ArgoCD instance starts. Its RBAC assertions therefore do not cover creating the ApplicationSet controller after updating an already-running instance. The existing 1-091_argocd_app_validate-applicationset-status_test.go covers the status transition, but it does not assert the ApplicationSet ClusterRole or ClusterRoleBinding.

Restore the ApplicationSet controller status assertion.

checkClusterConfig checks ApplicationSet RBAC objects but not Status.ApplicationSetController. Both tests can therefore pass when Argo CD is available, the server is running, and the RBAC resources exist while the ApplicationSet controller is not running. Add the assertion to the shared helper so both scenarios cover this condition.
