# Phase 3 — Validation Strategy

> Per-phase validation contract for feedback sampling during execution.

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest 4.0.18 + @testing-library/react + jsdom |
| **Config file** | `frontend/vite.config.ts` (test section) |
| **Quick run command** | `cd frontend && bun vitest run --reporter=verbose` |
| **Full suite command** | `cd frontend && bun vitest run` |
| **Estimated runtime** | ~20 seconds |

---

## Sampling Rate

- **After every task commit:** Run `cd frontend && bun vitest run --reporter=verbose`
- **After every plan wave:** Run `cd frontend && bun vitest run && bun run build`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 20 seconds

## Wave 0 Requirements

- [ ] `frontend/src/components/BudgetSetup.test.tsx` — stubs for IXTN-01 (budget form spinner)
- [ ] `frontend/src/pages/CategoriesPage.test.tsx` — stubs for IXTN-05 (delete confirmation), STATE-02 (empty state)
- [ ] `frontend/src/pages/DashboardPage.test.tsx` — stubs for STATE-01 (dashboard empty state)
- [ ] `frontend/src/components/BillsTracker.test.tsx` — stubs for STATE-03 (tinted skeleton)

**Existing tests to extend (no Wave 0 needed):**
- `LoginPage.test.tsx` — add IXTN-01 spinner assertion
- `RegisterPage.test.tsx` — add IXTN-01 spinner assertion
- `InlineEditCell.test.tsx` — add IXTN-02 pencil icon + IXTN-03 flash callbacks

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Pencil icon hover animation feels smooth | IXTN-02 | CSS transition quality | Hover over editable cells; pencil should fade in smoothly ~150ms |
| Save flash color is visually pleasant | IXTN-03 | Color perception | Edit and save a value; row should flash soft green, not harsh |
| Error flash + revert feels natural | IXTN-03 | Interaction quality | Trigger a save error; row should flash red briefly, value reverts |
| Empty state looks balanced and inviting | STATE-01/02 | Visual composition | View dashboard with no budgets; icon + text + CTA should feel balanced |
| Skeleton tinting matches section colors | STATE-03 | Visual consistency | Observe loading state; skeleton pulse colors should match their section |

---

## Validation Sign-Off

- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
- [ ] Wave 0 covers all MISSING references
- [ ] No watch-mode flags
- [ ] Feedback latency < 20s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
