## Summary Closes #176 Working as **Boromir** (DevOps Engineer) Mirrors the Sprint 7 Domain.Tests xUnit v3 pilot by upgrading Architecture.Tests from xunit 2.x to xunit.v3 3.2.2. ## Changes - **`tests/Architecture.Tests/Architecture.Tests.csproj`** - Replaced `<PackageReference Include="xunit"/>` with `<PackageReference Include="xunit.v3"/>` (version 3.2.2 centralized in `Directory.Packages.props`) - Added `<PackageReference Include="xunit.analyzers"/>` (version 1.27.0 centralized) - Added `xunit.runner.json` as `Content` item (matching Domain.Tests pattern) - **`tests/Architecture.Tests/xunit.runner.json`** — new file matching Domain.Tests Sprint 7 configuration ## Sprint 7 Pilot Context `Directory.Packages.props` already contained `xunit.v3 3.2.2`, `xunit.v3.assert`, `xunit.v3.extensibility.core`, and `xunit.analyzers 1.27.0` from the Sprint 7 Domain.Tests pilot. This PR wires up Architecture.Tests to use those centralized entries. ## NuGet Policy Compliance ✅ All versions remain in `Directory.Packages.props` — no version pins in `.csproj` ## Local Validation - `dotnet build`: ✅ 0 errors - `dotnet test tests/Architecture.Tests`: ✅ 11/11 passed - `dotnet test tests/Domain.Tests`: ✅ 42/42 passed (pilot unaffected) Co-authored-by: Boromir <boromir@squad.dev> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary Closes #177 Working as **Boromir** (DevOps Engineer) Validates CI passes cleanly with xUnit v3 packages in Architecture.Tests (from #176) and Domain.Tests (Sprint 7 pilot). ## CI Validation Findings ### Local Build & Test Results | Step | Result | Notes | |------|--------|-------| | `dotnet restore` | ✅ PASS | All packages resolved | | `dotnet build --configuration Release` | ✅ PASS | 0 errors, 306 pre-existing warnings (CA2007/CA1707 in integration tests — not xunit-related, pre-existing) | | `dotnet test tests/Architecture.Tests` | ✅ PASS | 11/11 tests passed | | `dotnet test tests/Domain.Tests` | ✅ PASS | 42/42 tests passed | ### Workflow Assessment | Workflow | Behaviour | Status | |----------|-----------|--------| | `squad-ci.yml` | Build-only gate on PR to dev/main | ✅ No changes needed | | `squad-preview.yml` | Full test suite on push to dev | ⚠️ Domain.Tests was missing — **added** | ### Workflow Change **`squad-preview.yml`** — Added `dotnet test tests/Domain.Tests` to the test matrix. The Sprint 7 Domain.Tests pilot was missing from CI gate despite being the reference implementation. Architecture.Tests was already present and now validates with xunit.v3. ## No Adjustments Needed xUnit v3 3.2.2 works drop-in with `Microsoft.NET.Test.Sdk 18.5.0` and `xunit.runner.visualstudio 3.1.5` (already centralized in `Directory.Packages.props`). No runner configuration changes required beyond the `xunit.runner.json` added in #176. ⚠️ This task was flagged as "needs review" — please have a squad member review before merging (CI workflow changes affect all contributors). --------- Co-authored-by: Boromir <boromir@squad.dev> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary Migrates Architecture.Tests test methods to xUnit v3 API conventions, following the Sprint 7 Domain.Tests pilot pattern. Closes #178 **Working as Gimli (Tester)** --- ## What Changed All 4 test files updated with proper xUnit v3 migration conventions: | File | Tests | Change | |------|-------|--------| | `DomainLayerTests.cs` | 4 | AAA comments + extract `assembly` variable for clean Arrange/Act split | | `VsaLayerTests.cs` | 3 | AAA comments + extract `domainAssembly` variable | | `ThemeLayerTests.cs` | 2 | AAA comments | | `CachingLayerTests.cs` | 2 | AAA comments | **Total: 11 tests migrated** ## xUnit v3 API Observations - `[Fact]` attribute is **identical** in xUnit v2 and v3 — no attribute changes required - No async/await patterns in architecture tests — no lifecycle changes needed - No `IClassFixture` / `ICollectionFixture` — stateless tests, no collection changes needed - FluentAssertions `.Should()` works unchanged with xUnit v3 - Parallelization via `xunit.runner.json` was already configured in Wave 1 (#182) ## Pattern Reference (Sprint 7 Domain.Tests Pilot) Followed the same approach as the Sprint 7 Domain.Tests migration: - xUnit v3 meta-package via `<PackageReference Include="xunit.v3"/>` ✅ (Wave 1) - `xunit.runner.json` with `parallelizeAssembly: true` ✅ (Wave 1) - Gimli Rule #3: AAA comments on all test methods ✅ (this PR) - Gimli Rule #6: File headers present on all files ✅ (pre-existing) ## Test Results ``` Passed! - Failed: 0, Passed: 11, Skipped: 0, Total: 11 — Architecture.Tests.dll Passed! - Failed: 0, Passed: 42, Skipped: 0, Total: 42 — Domain.Tests.dll ``` Zero failures. Ready to merge to `sprint/8-xunit-v3-pilot`. Co-authored-by: Boromir <boromir@squad.dev> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary Post-migration validation for Architecture.Tests xUnit v3 migration. No failures found. Closes #179 **Working as Gimli (Tester)** --- ## Findings After applying the xUnit v3 migration in PR #184, all 11 architecture tests pass with zero failures: ``` Passed! - Failed: 0, Passed: 11, Skipped: 0, Total: 11 — Architecture.Tests.dll (72ms) ``` **No fixes required.** The Architecture.Tests migration in Wave 2 is clean. ## Root Cause Analysis xUnit v3 is fully backward-compatible for all patterns used in Architecture.Tests: - `[Fact]` — identical in v2 and v3 ✅ - FluentAssertions `.Should()` — unchanged ✅ - NetArchTest.Rules builder chain — unchanged ✅ - No `IClassFixture` / `ICollectionFixture` patterns in use ✅ - No xUnit lifecycle overrides (`IAsyncLifetime`, `SetupAttribute`) ✅ The only migration work was Gimli Rule #3 compliance (AAA comments), which is purely cosmetic and cannot introduce test failures. ## Deliverables - ✅ Validated: 11 tests pass with xUnit v3 3.2.2 - ✅ Appended Sprint 8 Wave 2 learnings to `.squad/agents/gimli/history.md` - ✅ Drafted `gimli-xunit-v3-migration-pattern.md` decision (in local decisions inbox for Scribe) ## Prerequisite This PR should merge after #184 is merged to `sprint/8-xunit-v3-pilot`.

…181) - Creates docs/sprint-8-xunit-v3-pilot-retro.md with full retrospective - Covers Wave 1-3 delivery, what went well, improvements, learnings - Documents 11 arch tests + 42 domain tests passing (53+ combined) - Records key decisions from Boromir and Gimli inbox entries - Includes xUnit v3 rollout recommendations for Sprint 9+ - Updates Aragorn history.md with Sprint 8 learnings Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Features_Should_Not_Reference_Each_Other (and the comment "and vice versa") implies enforcing both directions, but the test only checks that MyBlog.Web.Features.BlogPosts does not depend on ...UserManagement. Either add the reciprocal assertion (UserManagement should not depend on BlogPosts) or rename/update the test/comment to match the single-direction rule being enforced.

+No individual `.csproj` version pins. See `.squad/decisions/inbox/boromir-xunit-v3-package-strategy.md`.


This retrospective references decision files under .squad/decisions/inbox/..., but that directory is gitignored, so readers of the repo won't be able to find these documents. Consider linking to the canonical .squad/decisions/decisions.md entries instead, or include the referenced decision docs in a tracked location.

 ### Learnings
 1. For MyBlog test coverage, a `ConfigureAwait(false)` cleanup in a MediatR pipeline behavior is non-observable unless tests explicitly assert synchronization-context behavior.
-2. Scope discipline matters here: do not churn nearby tests for unrelated convention gaps when the requested review is only about async continuation configuration.

Missing a blank line between the numbered list and the following ## heading. As written, many Markdown renderers treat the heading as part of list item 2, which breaks document structure.
