# Phase 17 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | xUnit + Moq (existing) |
| **Config file** | SharepointToolbox.Tests/SharepointToolbox.Tests.csproj |
| **Quick run command** | `dotnet test --filter "Category!=Integration"` |
| **Full suite command** | `dotnet test` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `dotnet test --filter "Category!=Integration"`
- **After every plan wave:** Run `dotnet test`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 15 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 17-01-01 | 01 | 1 | RPT-01, RPT-02 | unit | `dotnet test --filter "SharePointGroupResolver"` | ❌ W0 | ⬜ pending |
| 17-02-01 | 02 | 2 | RPT-01 | unit | `dotnet test --filter "HtmlExportService"` | ✅ | ⬜ pending |
| 17-02-02 | 02 | 2 | RPT-01 | unit | `dotnet test --filter "HtmlExportService"` | ✅ | ⬜ pending |

*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

---

## Wave 0 Requirements

- [ ] `SharepointToolbox.Tests/Services/SharePointGroupResolverTests.cs` — stubs for RPT-01, RPT-02
- [ ] Test fixtures for `ResolvedMember` and mock group data

*If none: "Existing infrastructure covers all phase requirements."*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Click group pill expands member list in browser | RPT-01 | Requires rendered HTML + browser interaction | Export HTML, open in browser, click group pill, verify member sub-row appears |
| "members unavailable" label renders on resolution failure | RPT-01 | Visual verification in browser | Export with mocked failure, verify italic label appears |

---

## 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 < 15s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
