test(integration): migrate Web.Tests.Integration to xUnit v3

[mpaulosky]

Summary

Migrates tests/Web.Tests.Integration from xUnit v2 to xUnit v3 (3.2.2), matching the pattern already established by Web.Tests and Web.Tests.Bunit.

Working as Gimli (Tester)

Closes #199

Changes

File	Change
Web.Tests.Integration.csproj	xunit → xunit.v3; runner JSON item: <None Update> → <Content Include>
IntegrationTest1.cs	Deleted — stale Aspire starter template, all methods commented out
MongoDbFixture.cs / RedisFixture.cs	IAsyncLifetime: async Task → async ValueTask (xUnit v3 requirement); file headers fixed
BlogPostIntegrationCollection.cs / RedisCachingCollection.cs	File headers fixed
MongoDbBlogPostRepositoryTests.cs	File header fixed; all async calls thread TestContext.Current.CancellationToken
BlogPostCacheServiceTests.cs	File header fixed; all async calls thread TestContext.Current.CancellationToken

xUnit v3 migration notes

• IAsyncLifetime now requires ValueTask for InitializeAsync and DisposeAsync — fixtures updated accordingly.
• xUnit1051 (use TestContext.Current.CancellationToken) resolved by threading ct through all repository and cache service calls. All methods already accepted CancellationToken as an optional parameter — no production code changes required.
• Runner JSON settings preserved: parallelizeAssembly: false / parallelizeTestCollections: true kept to avoid Docker container conflicts during parallel collection runs.

Verification

All pre-push gates passed:

• ✅ Release build (0 errors)
• ✅ Unit/arch tests: 241 passed
• ✅ Integration tests: 12/12 passed (MongoDB + Redis via Testcontainers)

Pull request overview

Migrates the tests/Web.Tests.Integration project from xUnit v2 to xUnit v3 to align with the established patterns used in the other test projects, including runner config handling and v3 async/cancellation conventions.

Changes:

• Updated the integration test project to reference xunit.v3 and include xunit.runner.json as copied content.
• Removed the stale Aspire starter/template test file (IntegrationTest1.cs).
• Updated fixtures/tests to match xUnit v3 requirements (IAsyncLifetime ValueTask methods) and to thread TestContext.Current.CancellationToken through async calls.

After deleting IntegrationTest1.cs, the test project no longer appears to use Aspire.Hosting.Testing (or the related entries) and there are no code references to the AppHost project either. Consider removing the unused package/usings and the AppHost project reference to reduce restore/build time and keep the integration suite focused; they can be re-added when Aspire-based tests are introduced again.

Technical Review

Migration correctness — all four v3 requirements applied correctly:

1. xunit → xunit.v3 — correct package swap; xunit.runner.visualstudio retained unchanged (supports both v2 and v3).
2. IAsyncLifetime ValueTask shape — MongoDbFixture and RedisFixture updated from async Task → async ValueTask. Correct fix for the xUnit v3 breaking interface change.
3. xUnit1051 / TestContext.Current.CancellationToken — all async repository and cache service calls now thread ct. Task.Delay(20, ct) is a precise improvement.
4. Runner JSON <Content Include> — correct swap from <None Update>. xUnit v3 requires content-copy semantics; PreserveNewest preserved.

IntegrationTest1.cs deletion — appropriate. Stale Aspire starter template with 100% commented-out methods has no place in the active suite.

Runner settings preserved — parallelizeAssembly: false / parallelizeTestCollections: true is correct for Testcontainers-based integration tests that share Docker containers. Changing this would introduce port conflicts and flaky tests.

File header corrections — Integration.Tests → Web.Tests.Integration fixed in all 6 files. Consistent with the repo copyright-header standard.

Scope — surgical. Nothing outside tests/Web.Tests.Integration/ was touched. No production code changes were needed.
