Sprint 8 retrospective (#181)#187
Conversation
## 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.

## 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`.

ThemeComponents_ShouldResideIn_ThemeNamespace currently filters to types that already reside in MyBlog.Web.Components.Theme, then asserts they reside in that same namespace. This makes the rule effectively tautological and it won’t catch theme components placed in the wrong namespace (and may still pass when there are zero matching types). Consider selecting theme components by a different predicate (name/base type/interface) and asserting they reside in the Theme namespace, or assert that all components outside the Theme namespace do not match the theme component criteria.

The comment says "BlogPosts slice should not reference UserManagement and vice versa", but the test only checks one direction (BlogPosts → UserManagement). Either add the inverse dependency check (UserManagement → BlogPosts) or adjust the comment so the intent matches the assertion.

This code fence doesn’t specify a language. The repo’s markdown rules expect fenced code blocks to declare a language (use e.g. text here) to satisfy validators and keep formatting consistent.

There was a problem hiding this comment.
The versions listed here don’t match the repo’s centralized package versions. Directory.Packages.props currently sets xunit.runner.visualstudio to 3.1.5 (not 3.1.1). Please update the document so it reflects the actual versions in use.

| ## Next Steps & Recommendations | ||
|
|
||
| ### Should Blazor.Tests adopt xUnit v3 next? | ||
|
|
||
| **Yes — recommended for Sprint 9.** The two projects with the most complex | ||
| migration surface are `Unit.Tests` and `Blazor.Tests`. `Blazor.Tests` uses | ||
| bUnit which has explicit xUnit v3 support. Migrating it next would complete | ||
| the pilot phase and establish the bUnit + xUnit v3 pattern. | ||
|
|
||
| **Suggested Sprint 9 scope:** | ||
| - Wave 1 (Boromir): Update `Blazor.Tests` packages | ||
| - Wave 2 (Gimli): Migrate test code, confirm bUnit compatibility | ||
| - Wave 3 (Pippin): ADR, (Aragorn): Retrospective | ||
|
|
||
| ### Should Unit.Tests be migrated alongside or after Blazor.Tests? | ||
|
|
||
| `Unit.Tests` and `Blazor.Tests` can potentially be done in the same sprint | ||
| in parallel waves if CI capacity allows. If sequenced, do `Blazor.Tests` first | ||
| (higher value, more interesting migration surface) and `Unit.Tests` second. |

The repo doesn’t have a tests/Blazor.Tests project (the bUnit test project is tests/Web.Tests.Bunit). Update the rollout recommendations to use the correct project name so the migration plan is actionable and doesn’t point to a non-existent path.
