NO-JIRA: Add unit tests for Cinder CSI ReadWriteOncePod access modes

[kchawlani19]

Analysis / Root cause:
The Create PersistentVolumeClaim form does not discover CSI access-mode capabilities dynamically. Allowed modes come from a static provisioner map in frontend/public/components/storage/shared.ts. For cinder.csi.openstack.org that map listed only ReadWriteOnce, so AccessModeSelector rendered ReadWriteOncePod as disabled. YAML creation of RWOP PVCs already worked on Cinder CSI (OpenShift 4.20 / OpenStack 18).

The mapping fix landed on main in #16870, but that PR did not close #16866 and added no unit tests.

Solution description:
Add regression tests for the provisioner access-mode helpers:

• cinder.csi.openstack.org allows ReadWriteOnce and ReadWriteOncePod for Filesystem and Block
• in-tree kubernetes.io/cinder includes RWOP without duplicates
• manila.csi.openstack.org is unchanged (no RWOP)
• ignoreReadOnly still filters ReadOnlyMany
• unknown provisioners still fall back to initialAccessModes

No mapping, API, extension, or i18n changes on main.

Screenshots / screen recording:
N/A (unit tests only; no UI change on main)

Test setup:
None. cd frontend && yarn test public/components/storage/__tests__/shared.spec.ts

Test cases:

1. Cinder CSI Filesystem/Block include RWOP
2. Cinder CSI does not include RWX or ROX
3. In-tree Cinder mapping has no duplicate RWOP entries
4. Manila CSI still does not offer RWOP
5. ignoreReadOnly filters ReadOnlyMany
6. Unknown provisioner returns initialAccessModes
7. Volume mode selector still allows Filesystem and Block for Cinder CSI + RWOP

Browser conformance:

• Chrome
• Firefox
• Safari (or Epiphany on Linux)

Additional info:
Closes #16866

Mapping fix: #16870
Cinder CSI capabilities: https://github.com/kubernetes/cloud-provider-openstack/blob/master/docs/cinder-csi-plugin/features.md

release-4.20 / release-4.21 / release-4.22 still have the original mapping bug. Backports of #16870 plus these tests are prepared locally.

Summary by CodeRabbit

• Tests
  • Expanded coverage for storage access mode selection across CSI and in-tree provisioners.
  • Added validation for read-only filtering, unknown-provisioner fallback, and Cinder CSI handling of supported access modes.
  • Added tests for provisioner mode mappings, duplicate prevention, and volume mode selection, including single-pod read/write volumes.

Walkthrough

The pull request adds tests for storage shared helpers. The tests cover Cinder CSI, in-tree Cinder, Manila CSI, unknown provisioners, ReadWriteOncePod handling, read-only filtering, provisioner mappings, and volume-mode mappings.

Changes

Storage helper regression coverage

Layer / File(s)	Summary
Provisioner mappings and fallback behavior frontend/public/components/storage/__tests__/shared.spec.ts	Adds tests for access-mode selection across supported provisioners, read-only filtering, unknown-provisioner fallback, and Cinder CSI exclusion of RWX and ROX. Tests also cover provisioner mode mappings and Cinder CSI ReadWriteOncePod volume modes.

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

Merge Risk: ⚪ Minimal · up to 65058

This change adds localized regression coverage without changing production behavior, so no actionable merge-blocking risk remains after normal checks and review.

Full details: Description check

Explanation

The description completes the required template sections and explains the problem, test coverage, setup, and scope. Browser checks are correctly left unselected because this PR contains unit tests only.

Full details: Linked Issues check

Explanation

The tests provide regression coverage for the linked objectives in #16866 and #16870, including Cinder CSI ReadWriteOncePod support, volume modes, duplicate prevention, Manila behavior, filtering, and fallback behavior.

Full details: Out of Scope Changes check

Explanation

The PR changes only the storage shared-helper unit tests. The changes are directly related to the linked Cinder CSI access-mode objectives and introduce no unrelated code, API, extension, or i18n changes.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 1 files.

Full details: Stable And Deterministic Test Names

Explanation

PASS. The PR adds only frontend/public/components/storage/__tests__/shared.spec.ts. All describe and it titles are literal, descriptive strings. No title contains generated identifiers, timestamps, dates, node or namespace names, IP addresses, UUIDs, interpolation, or concatenation. The titles describe stable storage behaviors and do not depend on run-time values.

Full details: Test Structure And Quality

Explanation

PASS: The pull request changes only frontend/public/components/storage/__tests__/shared.spec.ts, which is a Jest/TypeScript unit test file using describe and it, not Ginkgo test code. The tests call pure storage helper functions, create no cluster resources, and use no Eventually, Consistently, setup/cleanup hooks, or cluster operations. Therefore the Ginkgo-specific check is not applicable.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request changes only frontend/public/components/storage/__tests__/shared.spec.ts. The added tests use Jest describe/it, not Ginkgo It, Describe, Context, or When. They do not reference MicroShift-unavailable OpenShift APIs, namespaces, or unsupported cluster assumptions. The MicroShift Test Compatibility check is therefore not applicable.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request adds only frontend/public/components/storage/__tests__/shared.spec.ts. The file contains TypeScript/Jest describe and it unit tests for pure storage helpers. It adds no Ginkgo It, Describe, Context, or When e2e tests and makes no node, topology, scheduling, or HA assumptions.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only frontend/public/components/storage/__tests__/shared.spec.ts. The diff adds unit tests and contains no deployment manifest, operator, controller, replica, affinity, topology spread, node selector, taint, or PDB changes. The topology-aware scheduling check is therefore not applicable.

Full details: Ote Binary Stdout Contract

Explanation

PASS: The pull request changes only frontend/public/components/storage/__tests__/shared.spec.ts, a TypeScript Jest test file. The diff adds describe/it tests and imports storage helpers. It contains no Go OTE binary code, process-level setup, logging, or stdout writes. The OTE binary stdout contract is therefore not applicable.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request adds one TypeScript unit-test file, frontend/public/components/storage/__tests__/shared.spec.ts. It uses Jest-style lowercase describe/it, not Ginkgo e2e declarations. The tests only call local storage helper functions and contain no IPv4 addresses, IP parsing, URLs, DNS, registry access, or external connectivity requirements. The custom check is therefore not applicable.

Full details: No-Weak-Crypto

Explanation

The pull request adds only storage helper unit tests. The tests use access-mode strings and Jest assertions, with no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom cryptography, or secret/token comparisons.

Full details: Container-Privileges

Explanation

PASS. The pull request changes only one TypeScript unit-test file. The complete diff adds storage-helper assertions and adds no container or Kubernetes manifest. No added privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation declaration is present.

Full details: No-Sensitive-Data-In-Logs

Explanation

PASS: The pull request adds only unit tests in shared.spec.ts. The diff contains no logging calls, debug output, or log statements. It contains public provisioner identifiers as test inputs, but it does not log passwords, tokens, API keys, PII, session IDs, hostnames, or customer data.
