+
+### Decision 5: AppHost.Tests CI-Safety Pattern
+
+**Status:** ✅ Implemented  
+**Date:** 2026-07-20  
+**Author:** Aragorn (Lead / Architect Review)
+
+#### Context
+
+Fan-out review of `src/AppHost/` and `tests/AppHost.Tests/`. Five defects corrected.
+
+#### Decision: Null-safe DisposeAsync in all IAsyncLifetime fixtures
+
+When a fixture's `InitializeAsync` has an early-return path (e.g., `IsCI` guard), any
+disposable members initialized inside that method **must** be null-checked in `DisposeAsync`.
+The safe pattern is:
+
+```csharp
+public async ValueTask DisposeAsync()
+{
+    await (App?.DisposeAsync() ?? ValueTask.CompletedTask);
+}
+```
+
+`ClearCommandAppFixture` was calling `App.DisposeAsync()` unconditionally while `App` was
+declared `null!` and never assigned in CI — causing a `NullReferenceException` that masked
+the real skip intent.
+
+**Rule:** Every `IAsyncLifetime` (or `IAsyncDisposable`) fixture that has a guarded
+`InitializeAsync` must use null-safe disposal. Code review gate: reject fixtures
+with non-null-safe disposal where initialization can be skipped.
+
+#### Decision: Playwright AppHost tests are skip-in-CI, not skip-with-flag
+
+All Playwright E2E tests carry `[SkipInCIFact]` or `[SkipInCITheory]`. The `AspireManager`
+and `ClearCommandAppFixture` detect `CI=true` and skip their heavy DCP initialization.
+This is the accepted architectural pattern. Do not attempt to run these tests in CI
+without a proper DCP/Docker environment.
+
+#### Defects Corrected
+
+| # | Severity | File | Issue | Fix |
+|---|----------|------|-------|-----|
+| 1 | Critical | `ClearCommandAppFixture.cs` | `NullReferenceException` in `DisposeAsync` when CI=true | Null-safe `App?.DisposeAsync()` |
+| 2 | Minor | 10 test files | Copyright header: `Solution Name : IssueManager` | Corrected to `MyBlog` |
+| 3 | Minor | `WebPlaywrightTests.cs` | Doc comment said "IssueTrackerApp" | Corrected to "MyBlog web resource" |
+| 4 | Minor | `LayoutAuthenticatedTests.cs` | Vacuous assertion `>= 0` | Changed to `>= 1` |
+| 5 | Minor | `AspireManager.cs` | Log said "/3" but MaxRetryAttempts=5 | Updated to "/5" |
+
+#### Verification
+
+- ✅ `dotnet test tests/AppHost.Tests/AppHost.Tests.csproj --configuration Release --no-restore` → 61/61 tests passed (1 skipped)
+- ✅ `dotnet build MyBlog.slnx --configuration Release --no-restore` → Build succeeded
+
+#### Impact
+
+- Fixes critical runtime bug preventing safe CI test execution
+- Establishes code review gate for fixture disposal safety
+- Clears copyright and documentation hygiene issues across test suite
+- AppHost.Tests now CI-safe and ready for full integration testing

-  - `tests/Unit.Tests/Components/RazorSmokeTests.cs` — Component rendering smoke tests
+- **Automated UI coverage** — two complementary layers:
+  - **bUnit** (`tests/Web.Tests.Bunit`) — component rendering, auth states, JS interop mocks
+  - **Playwright E2E** (`tests/AppHost.Tests`) — full AppHost boot, real browser, MongoDB + Redis integration
+
+- **AppHost.Tests project** (Playwright + Aspire) lives at `tests/AppHost.Tests/`:
+  - `Layout/` — anonymous and authenticated nav, theme toggle persistence, color scheme picker
+  - `Pages/` — home page, 404 page
+  - `Auth/` — login fallback, /test/login cookie endpoint
+  - `MongoSeed/Clear/StatsIntegrationTests` — real MongoDB container via ClearCommandAppFixture
+  - Tests are **skipped in CI** via `[SkipInCIFact]` / `[SkipInCITheory]`; run locally with `dotnet test tests/AppHost.Tests`
+
+### AppHost.Tests Infrastructure Patterns
+
+#### ClearCommandAppFixture — MongoDB integration fixture
+
+```csharp
+[Collection("MyDomainIntegration")]
+public sealed class MyIntegrationTests(ClearCommandAppFixture fixture)
+{
+    [SkipInCIFact]
+    public async Task Something_Works()
+    {
+        using var client = new MongoClient(fixture.MongoConnectionString);
+        // ... test against live MongoDB container
+    }
+}
+```
+
+**Critical rules for ClearCommandAppFixture:**
+
+1. **No pre-warm**: Never call `PreWarmDcpAsync()` before starting MongoDB. The pre-warm
+   starts the AppHost (including MongoDB), stops it, and leaves the WiredTiger journal dirty.
+   Across multiple sequential collection fixtures sharing `mongo-data-v7`, this accumulates
+   to MongoDB exit-code-100 (unrecoverable storage engine). The retry policy is sufficient.
+
+2. **StopAsync before DisposeAsync**: `DisposeAsync` must call `App.StopAsync()` before
+   `App.DisposeAsync()` so MongoDB flushes the WiredTiger journal cleanly. Without this,
+   the next collection fixture finds a dirty volume and MongoDB exits immediately.
+
+3. **WaitForResourceAsync inside retry**: `App.ResourceNotifications.WaitForResourceAsync()`
+   for MongoDB must be inside the Polly retry boundary (not after it). MongoDB exit-code-100
+   fires an `OperationCanceledException` from that call, and only the retry policy can
+   recover from it.
+
+#### BasePlaywrightTests — ERR_NETWORK_CHANGED
+
+Playwright tests can encounter transient `ERR_NETWORK_CHANGED` on the first navigation
+(DHCP renewal, routing table update). `BasePlaywrightTests.RetryOnNetworkChangedAsync`
+wraps the entire page interaction with up to 3 retries. All `InteractWithPageAsync` and
+`InteractWithRolePageAsync` calls already use it — no per-test retry code needed.
+
+```csharp
+// In your test:
+await InteractWithPageAsync("web", async page =>
+{
+    await page.GotoAsync("/");  // ERR_NETWORK_CHANGED auto-retried by base class
+    // ...
+});
+```
+
+#### Theme toggle tests — trustworthy interactive state
+
+`ThemeToggleTestRuntime.WaitForThemeStateAsync` polls until Blazor is interactive
+(`window.themeManager` + `window.Blazor` present) before asserting. If never reached
+within 10 s, the test calls `Assert.Skip(...)` rather than failing — this is correct
+behavior for a slow-start CI-like environment.
+
+
   - `tests/Unit.Tests/Features/UserManagement/ProfileTests.cs` — Profile component claim assertions
   - bUnit tests use `BunitContext` (base class from bUnit; test-specific helpers in `TestAuthorizationService.cs`)

+
+2. INITIAL FAILURES
+   Command: dotnet build MyBlog.slnx --configuration Release --no-restore
+   Status: FAILED
+   Errors:
+   - 12 x LOGGEN012 in src/AppHost/MongoDbResourceBuilderExtensions.cs because

+   - Updated nullable-sensitive bUnit Arg.Is predicates to use null-safe
+     comparisons.
+   - Added tests/Web.Tests.Bunit/Testing/TestSender.cs to provide deterministic
+     MediatR request handling for mixed query/command bUnit scenarios that now
+     collide under newer NSubstitute behavior.
+   - Switched the affected bUnit tests to TestSender and registered the needed
+     query/command responses, including sequential query responses.

+
+3. DEFECTS FOUND AND FIXED
+
+   BUG-1 (CRITICAL): ClearCommandAppFixture.DisposeAsync NullReferenceException
+   - File: tests/AppHost.Tests/Infrastructure/ClearCommandAppFixture.cs
+   - Root cause: When CI=true, InitializeAsync returns early leaving App=null!.
+     DisposeAsync called App.DisposeAsync() unconditionally → NullReferenceException.
+   - Fix: Changed to null-safe pattern: await (App?.DisposeAsync() ?? ValueTask.CompletedTask)
+     (matches the safe pattern already used in AspireManager.DisposeAsync)
+
+   BUG-2 (MINOR): 10 files had wrong "Solution Name : IssueManager" in copyright headers
+   - Files: BasePlaywrightTests.cs, WebPlaywrightTests.cs, EnvVarTests.cs,
+     Infrastructure/AppHostTestCollection.cs, Infrastructure/AspireManager.cs,
+     Infrastructure/PlaywrightManager.cs, Layout/LayoutAnonymousTests.cs,
+     Layout/LayoutAuthenticatedTests.cs, Pages/HomePageTests.cs, Pages/NotFoundPageTests.cs
+   - Fix: Corrected all 10 headers to "Solution Name : MyBlog"
+
+   BUG-3 (MINOR): Doc comment in WebPlaywrightTests referenced "IssueTrackerApp"
+   - Fix: Updated to "MyBlog web resource"
+
+   BUG-4 (MINOR): Vacuous assertion in LayoutAuthenticatedTests.Layout_NavMenu_ContainsExpectedLinks
+   - Assertion: linkCount.Should().BeGreaterThanOrEqualTo(0) — always passes, tests nothing.
+   - Fix: Changed to BeGreaterThanOrEqualTo(1) — a nav must have at least one link.
+
+   BUG-5 (MINOR): AspireManager Polly retry log message said "(attempt {Attempt}/3)"
+     but MaxRetryAttempts = 5.
+   - Fix: Updated log template to "(attempt {Attempt}/5)"
+
+4. FINAL VERIFICATION
+   Command: dotnet test MyBlog.slnx --configuration Release --no-build (non-Playwright suite)
+   Status: SUCCESS
+   - Domain.Tests:           68/68  passed
+   - Architecture.Tests:     19/19  passed
+   - AppHost.Tests (model):  22/22  passed
+   - Web.Tests:             261/261 passed
+   - Web.Tests.Bunit:       112/112 passed
+   - Web.Tests.Integration:  36/36  passed
+   Total: 518 tests, 0 failures.
+
+   Note: Playwright/live-Aspire tests (39 tests) are skipped in CI by design
+   ([SkipInCIFact]/[SkipInCITheory]) and require local DCP+Docker+Playwright
