Summary

The E2E navigation test consistently fails when navigating to /c/main/intel-gpu/metrics. The heading matching /intel gpu.*metrics/i is never found within the 15-second timeout.

Test failure

Test: navigation between plugin views works (e2e/intel-gpu.spec.ts:59)
Run: PR #38 E2E run 23525917333

Locator: getByRole('heading', { name: /intel gpu.*metrics/i })
Expected: visible
Error: element(s) not found

Fails on both initial run and retry (#1) after 30 seconds total. Tests 1–5 and test 8 all pass. Only this navigation step fails.

E2E progression across branches

Branch E2E failure location Failure type
main nodes (/node/i) Strict mode violation (2 elements matched)
fix/e2e-nodes-heading-selector (PR #36) pods (/pod/i) Strict mode violation
fix/e2e-heading-selectors-pods-metrics-device-plugins (PR #38) metrics Element not found

The progression shows the selector fixes are working for the pages they address. The metrics failure is different in nature — it's not a strict-mode violation but a missing element.

What should be there

MetricsPage.tsx renders:

<SectionHeader title="Intel GPU — Metrics" />

SectionHeader from @kinvolk/headlamp-plugin renders an MUI Typography h1. The regex /intel gpu.*metrics/i should match "Intel GPU — Metrics" (em dash is matched by .*).

Possible root causes to investigate

  1. Context loading delay: MetricsPage returns <Loader> early if ctxLoading is true. If the useIntelGpuContext re-triggers loading on this route (or is slower than 15 seconds), the heading never renders.

  2. Route not registered: The /metrics route may not be properly wiring up MetricsPage, causing a redirect or rendering a different component.

  3. React state cycle: MetricsPage calls setFetching(true) in a useEffect immediately after context resolves. If this causes a brief unmount/remount cycle the heading could disappear during the assertion window (unlikely but possible).

  4. SectionHeader inside flex div: The heading is wrapped in a div with display: flex; justify-content: space-between. This shouldn't affect accessibility role, but worth verifying.

Reproduction steps

  1. Ensure E2E environment is running in privilegedescalation-dev
  2. Run npm run e2e
  3. Observe test 6 (navigation between plugin views works) fail at the metrics assertion

Impact

Blocks PR #38 from being approved. The heading selector fix in PR #38 is otherwise correct — this is a separate underlying issue with the MetricsPage that needs to be fixed for the navigation E2E test to pass.

Fix: PR #43 addresses this by moving SectionHeader outside the ctxLoading guard so the heading renders immediately. Locally verified: 108/108 unit tests pass including updated test asserting heading visible when ctxLoading=true. Awaiting CI approval + Patty E2E validation before PR #43 can be approved.

Update 2026-03-25: CI for PR #43 is now passing. However, E2E still fails due to a circular dependency with PR #44:

  • PR #43 (MetricsPage fix) fails E2E because the test spec on its branch has old broad selectors (/node/i) from main that violate strict mode — this is a pre-existing bug, not introduced by PR #43.
  • PR #44 (E2E selector fixes) fails E2E because MetricsPage heading still behind ctxLoading in the deployed plugin.

Gandalf has been asked (PRI-1019) to either combine these PRs or confirm the merge order. Once resolved, this bug will be closed.

Triaged. PR #43 (fix/metrics-heading-renders-immediately) directly addresses this — renders the heading immediately before ctxLoading resolves. PR #44 also tightens the E2E selectors to avoid strict mode violations. Both PRs assigned to Gandalf for E2E fix-up (PRI-1048).

PR #45 addresses this bug

PR #45 (fix: combine E2E infrastructure fixes) includes the fix for this issue in the MetricsPage heading change:

  • Root cause confirmed: The early return if (ctxLoading) return <Loader /> prevented the heading from ever rendering during the 15s E2E timeout window.
  • Fix: SectionHeader is now rendered outside the ctxLoading guard. The heading appears immediately on page navigation; the <Loader> renders below it while context data loads.

Unit test added confirming heading is visible when ctxLoading=true:

expect(screen.getByText('Intel GPU — Metrics')).toBeInTheDocument(); // ← heading visible
expect(screen.getByTestId('loader')).toHaveTextContent('Loading Intel GPU data...'); // ← loader below it

This issue should close when PR #45 merges. Currently blocked on CI approval gate (GitHub Actions settings).
