# Phase 10 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | xUnit 2.9.3 + Moq 4.20.72 |
| **Config file** | `SharepointToolbox.Tests/SharepointToolbox.Tests.csproj` |
| **Quick run command** | `dotnet test --filter "Category=Unit" --no-build` |
| **Full suite command** | `dotnet test` |
| **Estimated runtime** | ~15 seconds |

---

## Sampling Rate

- **After every task commit:** Run `dotnet test --filter "Category=Unit" --no-build`
- **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 |
|---------|------|------|-------------|-----------|-------------------|-------------|--------|
| 10-01-01 | 01 | 1 | BRAND-01 | unit | `dotnet test --filter "FullyQualifiedName~BrandingRepositoryTests" --no-build` | ❌ W0 | ⬜ pending |
| 10-01-02 | 01 | 1 | BRAND-06 | unit | `dotnet test --filter "FullyQualifiedName~BrandingServiceTests" --no-build` | ❌ W0 | ⬜ pending |
| 10-01-03 | 01 | 1 | BRAND-03 | unit | `dotnet test --filter "FullyQualifiedName~ProfileServiceTests" --no-build` | ✅ extend | ⬜ pending |
| 10-02-01 | 02 | 1 | UDIR-02 | unit | `dotnet test --filter "FullyQualifiedName~GraphUserDirectoryServiceTests" --no-build` | ❌ W0 | ⬜ pending |

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

## Wave 0 Requirements

- [ ] `SharepointToolbox.Tests/Services/BrandingRepositoryTests.cs` — stubs for BRAND-01 persistence round-trip
- [ ] `SharepointToolbox.Tests/Services/BrandingServiceTests.cs` — stubs for BRAND-06 magic bytes, compression, rejection
- [ ] `SharepointToolbox.Tests/Services/GraphUserDirectoryServiceTests.cs` — stubs for UDIR-02 pagination
- [ ] Extend `SharepointToolbox.Tests/Services/ProfileServiceTests.cs` — add BRAND-03 `ClientLogo` round-trip test

*Existing infrastructure covers test framework setup.*

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| MSP logo survives app restart | BRAND-01 | Requires full app lifecycle (start, import, close, reopen) | 1. Run app, import MSP logo 2. Close app 3. Reopen app 4. Verify logo still present in branding.json |
| Client logo isolated between tenants | BRAND-03 | Requires multi-profile JSON inspection | 1. Import logo for Tenant A 2. Verify Tenant B profile has no logo field 3. Delete Tenant A logo 4. Verify Tenant B unaffected |

---

## 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
