# Phase 05 Plan 03: Cable Test Station UI Summary
Three-panel Cable Test Station page at /test with SSE live readout, TanStack Query recent-tests list, Print & Next mutation workflow, and full Vitest unit test coverage.
## Tasks Completed
| # | Name | Commit | Files |
|---|------|--------|-------|
| 1 | API helpers + Cable Test Station page | 499dbb9 | web/src/api/test.ts, CableTestPage.tsx, router.tsx, TopBar.tsx |
| 2 | Unit tests for CableTestPage | 4e5a354 | CableTestPage.test.tsx, vitest.config.ts, src/test/setup.ts, package.json |
## What Was Built
`web/src/api/test.ts` exports three typed helpers:
- `submitCableTest(result)` — POST /api/test/cable, returns SubmitResponse
- `getRecentTests()` — GET /api/test/recent, returns TestResult[]
- `streamTestEvents(onReading, onError?)` — opens EventSource at /api/test/events, returns instance for caller-controlled close
`web/src/pages/CableTestPage.tsx` — three-column layout (single col on mobile via `grid-cols-1 lg:grid-cols-3`):
- Left: `ReadoutPanel` — displays live voltage/current/power/protocol from SSE state, or "No tester connected"
- Center: `LabelPanel` — controlled form for all TestResult fields, cable type toggle (USB/DP/HDMI), Print & Next button (bg-[#faff69]) that calls useMutation → submitCableTest, resets form on success
- Right: `RecentTestsPanel` — useQuery with 5s refetchInterval, renders up to 20 rows with cable type icon, HW ID, continuity chip, speed
SSE lifecycle: `useEffect` opens EventSource on mount via `streamTestEvents`, cleanup calls `es.close()` on unmount (mitigates T-05-08).
All values rendered via React JSX (no dangerouslySetInnerHTML) — mitigates T-05-07.
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Installed missing Vitest test framework**
- **Found during:** Task 2
- **Issue:** Plan stated "Vitest + RTL already in the project from Phase 3" but package.json had no test framework
- **Fix:** Installed vitest, @testing-library/react, @testing-library/user-event, @testing-library/jest-dom, jsdom; created vitest.config.ts and src/test/setup.ts
- **Files modified:** web/package.json, web/package-lock.json (new: vitest.config.ts, src/test/setup.ts)
- **Commit:** 4e5a354
**2. [Rule 1 - Bug] Mocked AppShell in tests to prevent TanStack Router crash**
- **Found during:** Task 2 (first test run)
- **Issue:** AppShell renders TopBar which uses TanStack Router `Link` — requires router context that throws in test environment
- **Fix:** Added `vi.mock('@/components/layout/AppShell')` rendering children-only div; added `window.matchMedia` stub for react-hot-toast Toaster
- **Files modified:** CableTestPage.test.tsx, src/test/setup.ts
- **Commit:** 4e5a354
## Verification
```
npm run build # exits 0 — CableTestPage-283Afuy4.js 13.20 kB
npm test -- --run CableTestPage # 4/4 tests passed
```
## Known Stubs
- **Live readout pre-population:** SSE readings update the readout panel display only. Form fields (speed_gbps, max_watts etc.) are NOT auto-populated from live readings — real driver parsing is not yet implemented (per plan: "the test fields remain manual until real driver parsing is implemented"). The form starts blank and requires manual entry.
