Keep the doc in sync if Analyzers-001 is fixed. **Resolution:** Resolved 2026-05-23 — Rewrote the analyzer's `` into five precise paragraphs: (1) guarded-call detection uses symbol identity, (2) DIM handling (covers Analyzers-005), (3) wrapper-lambda detection matches both containing-type symbol AND method name, with the lambda-not-bound-to-callSite-parameter limitation called out explicitly, (4) why `AlarmSurfaceInvoker` is not a wrapper home (covers Analyzers-002 narrative), (5) the existing capability-argument-not-enforced caveat.

The diff from `76d35d1` to `7286d320` is entirely the collection of prior-round fixes plus a migration of the test project's Roslyn package references to central package management (removing explicit `5.3.0` pins that conflicted with the SDK-shipped `5.0.0` compiler on this machine — correct change). + +| # | Category | Result | +|---|---|---| +| 1 | Correctness & logic bugs | No new issues | +| 2 | OtOpcUa conventions | No issues found | +| 3 | Concurrency & thread safety | No issues found | +| 4 | Error handling & resilience | No issues found | +| 5 | Security | No issues found | +| 6 | Performance & resource management | No issues found | +| 7 | Design-document adherence | No issues found | +| 8 | Code organization & conventions | No issues found | +| 9 | Testing coverage | Analyzers-008 | +| 10 | Documentation & comments | No issues found | + +### Analyzers-008 + +| Field | Value | +|---|---| +| Severity | Low | +| Category | Testing coverage | +| Location | `tests/Tooling/ZB.MOM.WW.OtOpcUa.Analyzers.Tests/UnwrappedCapabilityCallAnalyzerTests.cs` | +| Status | Resolved | + +**Description:** The 26-test suite added in the previous round covers most guarded-interface methods but leaves three async methods on guarded interfaces with no test at all and one wrapped-path (pass-clean) test missing: + +- `ISubscribable.UnsubscribeAsync` — no positive-trip test, no wrapped-pass test. +- `IAlarmSource.UnsubscribeAlarmsAsync` — no positive-trip test, no wrapped-pass test. +- `IAlarmSource.AcknowledgeAsync` — no positive-trip test, no wrapped-pass test. +- `IHistoryProvider.ReadEventsAsync` wrapped inside `CapabilityInvoker.ExecuteAsync` — DIM trip is tested (`Direct_ReadEventsAsync_OnConcreteDriverInheritingDIM_TripsDiagnostic`), but the corresponding pass-clean case (wrapped DIM call) is absent, leaving the suppression path for `ReadEventsAsync` unexercised. + +The analyzer is interface-typed and applies the same logic uniformly to every guarded-interface member, so these gaps do not hide a latent bug in the current code. However, missing positive-trip tests for three async guarded methods means a future regression (e.g. accidentally removing a metadata name from `GuardedInterfaceMetadataNames`) would not be caught by the test suite for those methods. + +**Recommendation:** Add one positive-trip test and one pass-clean test for each of the three untested async methods, and one wrapped pass-clean test for `ReadEventsAsync`. All four methods already appear in `StubSources` so no stub changes are required. + +**Resolution:** Resolved 2026-06-19 (SHA blank) — Added five regression tests: `Direct_UnsubscribeAsync_Call_TripsDiagnostic`, `Direct_UnsubscribeAlarmsAsync_Call_TripsDiagnostic`, `Direct_AcknowledgeAsync_Call_TripsDiagnostic`, `Wrapped_UnsubscribeAsync_InsideCapabilityInvokerLambda_PassesCleanly`, and `Wrapped_ReadEventsAsync_DIM_InsideCapabilityInvokerLambda_PassesCleanly`. All five pass against the existing analyzer with no source changes. diff --git a/tests/Tooling/ZB.MOM.WW.OtOpcUa.Analyzers.Tests/UnwrappedCapabilityCallAnalyzerTests.cs b/tests/Tooling/ZB.MOM.WW.OtOpcUa.Analyzers.Tests/UnwrappedCapabilityCallAnalyzerTests.cs index a6eaf861..0fcaab12 100644 --- a/tests/Tooling/ZB.MOM.WW.OtOpcUa.Analyzers.Tests/UnwrappedCapabilityCallAnalyzerTests.cs +++ b/tests/Tooling/ZB.MOM.WW.OtOpcUa.Analyzers.Tests/UnwrappedCapabilityCallAnalyzerTests.cs @@ -833,6 +833,129 @@ namespace ZB.MOM.WW.OtOpcUa.Server { diags.ShouldBeEmpty(); } + // ======================================================================= + // Analyzers-008 — missing trip + pass-clean tests for ISubscribable.UnsubscribeAsync, + // IAlarmSource.UnsubscribeAlarmsAsync, IAlarmSource.AcknowledgeAsync, and the wrapped + // (pass-clean) path for IHistoryProvider.ReadEventsAsync (DIM). + // ======================================================================= + + /// Verifies that a direct UnsubscribeAsync call trips the diagnostic. + [Fact] + public async Task Direct_UnsubscribeAsync_Call_TripsDiagnostic() + { + const string userSrc = """ +using System.Threading; +using System.Threading.Tasks; +using ZB.MOM.WW.OtOpcUa.Core.Abstractions; + +namespace ZB.MOM.WW.OtOpcUa.Server { + public sealed class BadUnsubscribe { + public async Task DoIt(ISubscribable driver, ISubscriptionHandle handle) { + await driver.UnsubscribeAsync(handle, CancellationToken.None); + } + } +} +"""; + var diags = await Compile(userSrc); + diags.Length.ShouldBe(1); + diags[0].GetMessage().ShouldContain("UnsubscribeAsync"); + } + + /// Verifies that a wrapped UnsubscribeAsync call inside a CapabilityInvoker lambda passes cleanly. + [Fact] + public async Task Wrapped_UnsubscribeAsync_InsideCapabilityInvokerLambda_PassesCleanly() + { + const string userSrc = """ +using System.Threading; +using System.Threading.Tasks; +using ZB.MOM.WW.OtOpcUa.Core.Abstractions; +using ZB.MOM.WW.OtOpcUa.Core.Resilience; + +namespace ZB.MOM.WW.OtOpcUa.Server { + public sealed class GoodUnsubscribe { + public async Task DoIt(ISubscribable driver, ISubscriptionHandle handle, CapabilityInvoker invoker) { + await invoker.ExecuteAsync(DriverCapability.AlarmSubscribe, "h1", + async ct => await driver.UnsubscribeAsync(handle, ct), + CancellationToken.None); + } + } +} +"""; + var diags = await Compile(userSrc); + diags.ShouldBeEmpty(); + } + + /// Verifies that a direct UnsubscribeAlarmsAsync call trips the diagnostic. + [Fact] + public async Task Direct_UnsubscribeAlarmsAsync_Call_TripsDiagnostic() + { + const string userSrc = """ +using System.Threading; +using System.Threading.Tasks; +using ZB.MOM.WW.OtOpcUa.Core.Abstractions; + +namespace ZB.MOM.WW.OtOpcUa.Server { + public sealed class BadAlarmUnsubscribe { + public async Task DoIt(IAlarmSource source, IAlarmSubscriptionHandle handle) { + await source.UnsubscribeAlarmsAsync(handle, CancellationToken.None); + } + } +} +"""; + var diags = await Compile(userSrc); + diags.Length.ShouldBe(1); + diags[0].GetMessage().ShouldContain("UnsubscribeAlarmsAsync"); + } + + /// Verifies that a direct AcknowledgeAsync call trips the diagnostic. + [Fact] + public async Task Direct_AcknowledgeAsync_Call_TripsDiagnostic() + { + const string userSrc = """ +using System.Collections.Generic; +using System.Threading; +using System.Threading.Tasks; +using ZB.MOM.WW.OtOpcUa.Core.Abstractions; + +namespace ZB.MOM.WW.OtOpcUa.Server { + public sealed class BadAcknowledge { + public async Task DoIt(IAlarmSource source) { + await source.AcknowledgeAsync(new List(), CancellationToken.None); + } + } +} +"""; + var diags = await Compile(userSrc); + diags.Length.ShouldBe(1); + diags[0].GetMessage().ShouldContain("AcknowledgeAsync"); + } + + /// Verifies that a wrapped ReadEventsAsync DIM call inside a CapabilityInvoker lambda passes cleanly. + [Fact] + public async Task Wrapped_ReadEventsAsync_DIM_InsideCapabilityInvokerLambda_PassesCleanly() + { + // ReadEventsAsync is a DIM — the wrapped path must not trip the diagnostic. + const string userSrc = """ +using System; +using System.Threading; +using System.Threading.Tasks; +using ZB.MOM.WW.OtOpcUa.Core.Abstractions; +using ZB.MOM.WW.OtOpcUa.Core.Resilience; + +namespace ZB.MOM.WW.OtOpcUa.Server { + public sealed class GoodHistoryEvents { + public async Task DoIt(IHistoryProvider provider, CapabilityInvoker invoker) { + _ = await invoker.ExecuteAsync(DriverCapability.Read, "h1", + async ct => await provider.ReadEventsAsync(null, DateTime.MinValue, DateTime.MaxValue, 0, ct), + CancellationToken.None); + } + } +} +"""; + var diags = await Compile(userSrc); + diags.ShouldBeEmpty(); + } + private static async Task> CompileWithoutStubs(string userSource) { var syntaxTrees = new[] { CSharpSyntaxTree.ParseText(userSource) };
