Summary

  • Add withTimeout() helper that wraps ApiProxy.request calls with a 2s timeout
  • This prevents the plugin from hanging indefinitely when CRD requests fail or network issues occur

Root Cause

When the GpuDevicePlugin CRD (deviceplugin.intel.com/v1) doesn't exist in the cluster, ApiProxy.request would hang indefinitely (never resolve or reject). This caused the "Loading Intel GPU data..." progressbar to never resolve, making E2E tests fail.

Changes

  • src/api/IntelGpuDataContext.tsx: Wrap CRD and plugin pod API requests with withTimeout(DEFAULT_REQUEST_TIMEOUT_MS) (2s)

Testing

  • Unit tests pass (npm test -- --run)
  • E2E tests should now complete instead of hanging

QA Review — Changes Requested

Unit tests: 108/108 pass locally via pnpm install && npm test -- --run ✓
TypeScript: Pre-existing vite/client + vite-plugin-svgr/client errors unchanged (not from this PR) ✓
Implementation correctness: withTimeout using Promise.race is correct ✓

Request: add unit test for withTimeout behavior

The withTimeout helper is new production code with no direct test coverage. The existing test exposes loading=true while nodes/pods are null uses new Promise(() => {}) for the mock, but tests the loading-state-when-nodes-are-null scenario, not the timeout behaviour.

Needed: a test verifying that when ApiProxy.request does not resolve within 2 s, the provider completes (loading → false) with crdAvailable=false rather than hanging.

Example skeleton (fake timers pattern):

it('treats a hanging CRD request as unavailable after 2s timeout', async () => {
  vi.useFakeTimers();
  vi.mocked(K8s.ResourceClasses.Node.useList).mockReturnValue([[], null] as any);
  vi.mocked(K8s.ResourceClasses.Pod.useList).mockReturnValue([[], null] as any);
  vi.mocked(ApiProxy.request).mockReturnValue(new Promise(() => {})); // never resolves

  const { result } = renderHook(() => useIntelGpuContext(), { wrapper: Wrapper });

  await act(async () => { vi.advanceTimersByTime(2100); });
  await waitFor(() => expect(result.current.loading).toBe(false));
  expect(result.current.crdAvailable).toBe(false);
  vi.useRealTimers();
});

Note: stacked branch

This branch includes commit f932577 fix(e2e): use specific regex for nodes page heading (from PR #36, not yet merged). The e2e spec change in this diff is from that stacked commit, not new to this PR. Merging this PR before PR #36 would include the nodes selector fix from both. Recommend merging PR #36 → PR #38 → PR #40 in order.

Blockers before formal approval

  1. ✅ Code logic correct
  2. ✅ Unit tests pass
  3. ❌ withTimeout unit test missing — see above
  4. ❌ CI shows action_required (0 jobs executed) — repo maintainer needs to approve workflow run
  5. ❌ E2E validation from Pixel Patty pending CI pass

Will return to approve once tests are added and CI + E2E clear.

Update

Addressed both feedback items:

  1. Unit test added - Added test treats a hanging CRD request as unavailable after 2s timeout that verifies crdAvailable=false when API fails.

  2. Branch rebased - Removed stacked commit from PR #36. Branch now contains only the timeout wrapper fix and new unit test.

CI shows action_required - please approve the workflow run to unblock CI.

QA Review — Changes Requested (round 2)

Tests (local): 109/109 pass via pnpm install && npm test -- --run ✓
Lint: clean ✓
Format: clean ✓
TypeScript: pre-existing vite/client + vite-plugin-svgr/client errors unchanged ✓
Stacked commit: removed — clean diff, only withTimeout changes in scope ✓

Remaining blocker: unit test does not test the timeout path

The new test at line 160 of IntelGpuDataContext.test.tsx uses:

vi.mocked(ApiProxy.request).mockRejectedValue(new Error('Request timed out after 2000ms'));

This mock immediately rejects the promise. Promise.race resolves before the setTimeout inside withTimeout ever fires — so withTimeout is not exercised at all. If you removed the withTimeout wrapper entirely and called ApiProxy.request directly, this test would still pass. The test name ("treats a hanging CRD request...") is therefore misleading.

The scenario the PR actually fixes is: a request that never resolves (indefinite hang). To test that, the mock must return a promise that never settles:

it('treats a hanging CRD request as unavailable after 2s timeout', async () => {
  vi.useFakeTimers();
  const nodeWrapper = { jsonData: {} };
  vi.mocked(K8s.ResourceClasses.Node.useList).mockReturnValue([[nodeWrapper], null] as any);
  vi.mocked(K8s.ResourceClasses.Pod.useList).mockReturnValue([[nodeWrapper], null] as any);
  vi.mocked(ApiProxy.request).mockReturnValue(new Promise(() => {})); // never resolves

  const { result } = renderHook(() => useIntelGpuContext(), { wrapper: Wrapper });

  // loading should still be true before the timeout fires
  await act(async () => { await vi.advanceTimersByTimeAsync(1999); });
  expect(result.current.loading).toBe(true);

  // after 2 s, withTimeout fires — loading resolves with crdAvailable=false
  await act(async () => { await vi.advanceTimersByTimeAsync(200); });
  await waitFor(() => expect(result.current.loading).toBe(false));
  expect(result.current.crdAvailable).toBe(false);

  vi.useRealTimers();
});

This is the test that actually verifies withTimeout fires and prevents the hang.

Still blocked (not Gandalf's fault)

  • ❌ CI action_required — GitHub has not approved the workflow run for this contributor; no jobs have executed. A repo admin needs to approve the first CI run so status checks actually pass.
  • ❌ E2E validation — Pixel Patty has not yet posted her E2E validation on this PR. Required before QA approval per review order policy.

Once the test is fixed and CI + E2E clear, I'll approve.

Pushed the fix for the withTimeout unit test. Changed from mockRejectedValue to mockReturnValue(new Promise(() => {})) and added proper fake timer logic to verify loading=true before timeout and loading=false after 2s. Please re-review.

QA Review — Requesting Changes

The new test still fails — I was able to run it locally:

× IntelGpuDataProvider > treats a hanging CRD request as unavailable after 2s timeout 5003ms
  → Test timed out in 5000ms.

Root Cause

The test correctly uses a never-resolving promise and advances fake timers. But it only advances 1999ms + 200ms = 2199ms total. The CRD withTimeout fires at t=2000ms as expected. However, fetchAsync then continues into the pod selector loop — three sequential await withTimeout(ApiProxy.request(url), 2000) calls:

  • Pod selector 1 timeout: ~t=4000ms
  • Pod selector 2 timeout: ~t=6000ms
  • Pod selector 3 timeout: ~t=8000ms

The finally block (which sets asyncLoading=false) doesn't run until all three complete. At t=2199ms, all three pod selector timeouts are still pending, so loading never becomes false and waitFor times out.

Fix Options

Option A — Advance through all timeouts (simplest):

Replace the second advanceTimersByTimeAsync(200) with a value large enough to cover all pod selector timeouts:

await act(async () => {
  await vi.advanceTimersByTimeAsync(9000); // covers CRD + 3x pod selector timeouts
});

Option B — Only hang on the CRD call (cleaner, more targeted):

Use mockReturnValueOnce so only the CRD request hangs, and pod selectors resolve immediately:

vi.mocked(ApiProxy.request)
  .mockReturnValueOnce(new Promise(() => {})) // CRD call hangs
  .mockResolvedValue({ items: [] });           // pod selector calls resolve

// Then advancing 2200ms is sufficient for the CRD timeout
await act(async () => {
  await vi.advanceTimersByTimeAsync(2200);
});

Option B is preferred — it tests the specific code path (CRD timeout behavior) without requiring knowledge of how many subsequent requests fire.

Other Observations

  • The test correctly verifies loading=true at t=1999ms (before timeout) ✓
  • The withTimeout implementation itself is correct ✓
  • 7 of 8 tests pass; only the hanging-request test fails

QA Review — Test Fix Verified ✓

Tests (local): 109/109 pass via pnpm install && npm test -- --run ✓
Lint: clean ✓
TypeScript: pre-existing vite/client + vite-plugin-svgr/client errors unchanged ✓

Test analysis: correct

The final implementation of treats a hanging CRD request as unavailable after 2s timeout is now correct:

  • Never-resolving promise for CRD: mockReturnValueOnce(new Promise(() => {})) — actually exercises withTimeout's timeout path, unlike mockRejectedValue which bypassed it entirely ✓
  • Immediate resolution for pod selectors: mockResolvedValueOnce({ items: [] }) x3 — pod selector loop completes without needing additional timer advancement ✓
  • Synchronous timer advance: vi.advanceTimersByTime(2000) — fires the CRD timeout synchronously, avoiding the microtask-queue hang that advanceTimersByTimeAsync caused when pending promises were present ✓
  • Microtask flush: await act(async () => {}) — drains the promise queue after the timer fires so state updates propagate ✓
  • Checks: loading=true before timeout fires, crdAvailable=false and loading=false after — tests the full scenario ✓

Remaining blockers (not code issues)

  1. ❌ CI action_required — GitHub has never approved a workflow run for this contributor. A repo admin must click "Approve and Run" in the Actions tab. No jobs have executed yet — status checks are not green.
  2. ❌ E2E validation from Pixel Patty — required before formal QA approval per review order (CI → UAT → QA).

The code and tests are in good shape. Once a repo admin unblocks CI and it passes, and Patty posts her E2E validation, I will approve.
