WalkthroughThe PR adds a Ginkgo e2e suite for TLS-enabled MinIO backup and restore. It provisions certificates and backup storage, validates full namespace recovery, and verifies ConfigMaps-only restore filtering. ChangesMinIO TLS backup and restore
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This PR adds a TLS-backed MinIO backup and restore test flow. It is mergeable with owner follow-up, but the current test can expose an internal endpoint in logs, miss cleanup failures, accept altered restored ConfigMap values, and intermittently race namespace deletion, reducing test reliability and defect detection.

Full details: Stable And Deterministic Test NamesExplanation PASS: The pull request adds one static Full details: Test Structure And QualityExplanation The new suite violates the assertion-message requirement and has an incomplete namespace cleanup wait. Many changed assertions are bare, including DPA creation (lines 159 and 270), AWS_CA_BUNDLE verification (173), application resource creation (178, 189, 201, 279, 286, 294), backup and restore operations (206, 215, 236, 245, 299, 306, 307, 317, 326, 327), and cleanup (260, 342). The suite also deletes the application namespace in AfterEach at line 150 without checking the error or waiting for deletion. The filter test deletes the namespace at line 311 and immediately creates a restore at line 317. The first test correctly waits for deletion at lines 228-231, and nearby suites use Eventually(IsNamespaceDeleted(...)) after deletion. All explicit Eventually calls in the new file have finite timeouts, and the shared BeforeAll/AfterAll MinIO lifecycle follows the existing cacert suite pattern. Resolution Add a meaningful diagnostic message to every Expect and Should assertion, including every Eventually call. Include the operation, resource name, and expected state. After every application namespace deletion, assert the delete result and wait with the existing IsNamespaceDeleted helper and a finite timeout before creating a restore or starting the next test. Apply the same wait in BeforeAll cleanup and AfterEach cleanup. Do not discard cleanup errors; report them with resource-specific messages. Keep the existing finite timeouts for DPA, Velero, BSL, backup, restore, and namespace waits. Full details: Microshift Test CompatibilityExplanation PASS: The new Ginkgo suite uses Kubernetes core resources (Namespaces, Secrets, ConfigMaps), an apps/v1 Deployment through the existing MinIO helper, Velero resources, and the OADP DataProtectionApplication CR. These are not the unavailable OpenShift APIs listed by the check. The suite does not reference Project, BuildConfig, DeploymentConfig, ClusterOperator, OLM, machine, monitoring, operator, restricted control-plane namespaces, or another OpenShift API group. It also has no multi-node, scaling, feature-gate, upgrade, or multi-replica control-plane assumption. The added file is the only change in the pull request; the MinIO helper and shared AWS_CA_BUNDLE helper were pre-existing. Full details: Single Node Openshift (Sno) Test CompatibilityExplanation PASS: The pull request adds two Ginkgo tests, but neither test contains a multi-node or HA assumption. The tests create Kubernetes resources, run one MinIO Deployment replica, use a Service, and perform backup/restore operations. The MinIO helper has no affinity, topology spread, node selection, node drain, scaling, or multi-endpoint behavior. The added file also has no SNO skip guard, but no guard is needed because the tests are compatible with SNO. Full details: Topology-Aware Scheduling CompatibilityExplanation PASS: The pull request adds only Full details: Ote Binary Stdout ContractExplanation No changed process-level stdout write is present.

The suite discards cleanup and must-gather errors. A failed deletion can leave stale resources, hide the cause of a failure, and affect the next ordered test.

Do not log the MinIO endpoint.
minioURL can contain an internal cluster hostname. Do not write it to test logs or CI artifacts.
As per coding guidelines, “Flag logging that may expose passwords, tokens, API keys, PII, session IDs, internal hostnames, or customer data.”

Add failure messages to the assertions that omit them.
Several Expect and Eventually calls have no diagnostic message. Add a message that identifies the failed operation and target resource.
As per coding guidelines, “Ginkgo test assertions should include meaningful failure messages to help diagnose what went wrong.”

Wait for namespace deletion before starting the filtered restore.
lib.DeleteNamespace only sends the delete request. It does not wait for the namespace to disappear. If the namespace remains in Terminating, the restore can fail intermittently. Wait for lib.IsNamespaceDeleted before creating the restore.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the restored ConfigMap values.
The helper only checks that both keys exist. A restore that changes either value still passes, so this does not verify the stated ConfigMap integrity coverage.
Proposed fix
- gomega.Expect(cm.Data).To(gomega.HaveKey("config.yaml"), "ConfigMap should contain config.yaml")
- gomega.Expect(cm.Data).To(gomega.HaveKey("data.json"), "ConfigMap should contain data.json")

Why the changes were made
Closes #2403. This PR adds comprehensive e2e coverage for OADP backup and restore operations using MinIO as a BackupStorageLocation with TLS encryption.
This test validates the full operator behavior end-to-end:
This provides test coverage for self-hosted/on-premises S3-compatible storage scenarios where custom CA certificates are required for TLS validation.
