### Test project reorganization
Splits the integration- vs unit-test boundary along **project
boundaries**
and introduces a runtime-tier split for subscription tests so the
mainline
CI no longer drags in stress / durable suites.
**New projects:**
- `Opc.Ua.Stress.Tests` ΓÇö cross-area stress tier (designed to
absorb
session / channel / pub-sub stress in future). Seeded with the 6
subscription stress classes (`SubscriptionDepthTests`,
`SubscriptionBasicDepthTests`, `MonitoredItemDepthTests`,
`SubscriptionTransferDepthTests`, `SubscriptionPublishTooManyTests`,
`SubscriptionMultipleTests`). **Excluded from mainline CI; runs
nightly.**
- `Opc.Ua.Subscriptions.Durable.Tests` ΓÇö durable-subscription tier
(needs `DurableSubscriptionsEnabled` + storage-backed lifetime).
Receives `SubscriptionDurableTests` plus the migrated
`DurableSubscriptionTest` and `DurableSubscriptionTestDebug`.
**Excluded from mainline CI; runs nightly.**
- `Opc.Ua.Features.Tests` ΓÇö cross-feature integration tier.
Receives the
`[OneTimeSetUp]`-bootstraps-its-own-server integrations for AliasNames
(Part 17), Roles (Part 18), FileSystem (Part 5 §C / Part 20), and
NodeCache. Also absorbs the misplaced
`Tests/Opc.Ua.History.Tests/FileSystemTests.cs`.
**Client.Tests cleanup (~28 files moved):**
- `Opc.Ua.Sessions.Tests` (existing) gains 10 session integration files
plus the 4 session benchmark files inline (`LoadTest`,
`RequestHeaderTest`, `TraceableRequestHeaderTest`,
`SecurityPolicyBenchmarks`).
- `Opc.Ua.Subscriptions.Tests` (existing) gains 4 subscription
integration files plus `PooledNotificationBenchmarks` inline.
- `Opc.Ua.Client.ComplexTypes.Tests` (existing) gains all
`ComplexTypes/*` integration files. The Client.Tests copy of
`TypeSystemClientTest.cs` (a stale near-duplicate) is removed.
- Benchmarks **stay inline** as `[Test]` + BenchmarkDotNet dual-use; no
new benchmark project (per the approved plan).
**CI pipeline:**
- `.azurepipelines/test.yml` now filters
`TestCategory!=LongRunning&TestCategory!=Stress` on the mainline run.
- `-ExcludeFileName` now accepts a comma-separated list. The mainline
matrix excludes the 3 nightly-tier project files alongside the
existing `Opc.Ua.Aot.Tests.csproj`.
- `get-matrix.ps1` enhanced to support multi-pattern excludes.
`InternalsVisibleTo` extended on `Opc.Ua.Client` and `Opc.Ua.Server` to
grant the new test projects access. All affected projects build clean
(`0 Error`) for `net10.0`.
### Fix 8 skipped tests flagged as suspected bugs
Triage of every `[Ignore]` / `[Explicit]` test in `Tests/**` surfaced 8
entries labelled as suspected production bugs. After inspection:
- **1 real production bug** ΓÇö the
`CancellationTokenSource.CancelAsync`
polyfill for netstandard2.0 / netfx was running cancellation callbacks
inline on the caller's thread, deadlocking dispose paths
(`SubscriptionManager.DisposeAsync`, etc.) when a callback awaits on
the caller's `SynchronizationContext`. Fixed at the polyfill root by
hoisting `Cancel()` onto the ThreadPool via `Task.Run`, matching real
.NET 8+ semantics. Caveat (deferred `IsCancellationRequested`
transition) documented inline; all in-repo callers use
`await cts.CancelAsync()` so the deviation is invisible. Test
`DrainAsyncWaitsForInFlightPublishToCompleteAsync` un-ignored ΓÇö
verified passes on net48 (943 ms) and net10.0 (1 s).
- **2 flaky tests stabilized** ΓÇö both
`ValidateMetaDataUpdateTimeNonZeroIsSentPeriodically` (MQTT JSON &
UADP) now use `Stopwatch.GetTimestamp()` instead of `DateTime.Now`,
compute deviation against the **median** interval (not the configured
cadence, so a startup hiccup doesn't skew the run), and use a
proportional `max(interval / 4, 50 ms)` tolerance. `[Ignore]` removed,
`[Category("LongRunning")]` retained.
- **1 mis-labelled "bug"** ΓÇö
`UnorderedMessagesWouldBeLostForSequentialPublishingAsync` asserts the
*documented* lossy trade-off of strict sequential publishing.
`[Explicit]`
removed and renamed to
`OldMessagesAbandonedAfterRepublishTimeoutInSequentialModeAsync`; it's
now a CI-verified regression test for the WAI behavior.
- **4 false positives** ΓÇö `JsonEncoderTestsOld.cs` (16 kLOC) was
excluded from compilation via `<Compile Remove>` and never reached the
runner. The 4 `[Ignore("ProductionBugSuspected")]` markers inside were
orphaned source from a previous JsonEncoder API. Active coverage lives
in `JsonEncoderTests.cs` and `JsonValidationData` fixtures. Deleted
the orphan file and the now-redundant `<Compile Remove>` line.
