# Phase 1 — Validation Strategy

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

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | xUnit 2.x |
| **Config file** | none — Wave 0 installs |
| **Quick run command** | `dotnet test --filter "Category=Unit" --no-build` |
| **Full suite command** | `dotnet test --no-build` |
| **Estimated runtime** | ~30 seconds |

---

## Sampling Rate

- **After every task commit:** Run `dotnet test --filter "Category=Unit" --no-build`
- **After every plan wave:** Run `dotnet test --no-build`
- **Before `/gsd:verify-work`:** Full suite must be green
- **Max feedback latency:** 30 seconds

## Wave 0 Requirements

- [ ] `SharepointToolbox.Tests/SharepointToolbox.Tests.csproj` — xUnit test project; packages: xunit, xunit.runner.visualstudio, Moq, Microsoft.NET.Test.Sdk
- [ ] `SharepointToolbox.Tests/Services/ProfileServiceTests.cs` — covers FOUND-02, FOUND-10
- [ ] `SharepointToolbox.Tests/Services/SettingsServiceTests.cs` — covers FOUND-12
- [ ] `SharepointToolbox.Tests/Auth/MsalClientFactoryTests.cs` — covers FOUND-03
- [ ] `SharepointToolbox.Tests/Auth/SessionManagerTests.cs` — covers FOUND-04
- [ ] `SharepointToolbox.Tests/ViewModels/FeatureViewModelBaseTests.cs` — covers FOUND-05, FOUND-06
- [ ] `SharepointToolbox.Tests/Localization/TranslationSourceTests.cs` — covers FOUND-09
- [ ] `SharepointToolbox.Tests/Integration/LoggingIntegrationTests.cs` — covers FOUND-08

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| Global exception handler shows MessageBox on unhandled exception | FOUND-07 | UI dialog cannot be asserted in xUnit without a WPF test harness | Launch app; trigger an unhandled exception via debug; verify MessageBox appears and log is written |

---

## 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 < 30s
- [ ] `nyquist_compliant: true` set in frontmatter

**Approval:** pending
