ZB.MOM.WW.OtOpcUa.Analyzers.Tests

Roslyn analyzer — detect unwrapped driver-capability calls (OTOPCUA0001). Closes task #200 . New netstandard2.0 analyzer project src/ZB.MOM.WW.OtOpcUa.Analyzers registered as an <Analyzer>-item ProjectReference from the Server csproj so the warning fires at every Server compile. First (and only so far) rule OTOPCUA0001 — "Driver capability call must be wrapped in CapabilityInvoker" — walks every InvocationOperation in the AST + trips when (a) the target method implements one of the seven guarded capability interfaces (IReadable / IWritable / ITagDiscovery / ISubscribable / IHostConnectivityProbe / IAlarmSource / IHistoryProvider) AND (b) the method's return type is Task, Task<T>, ValueTask, or ValueTask<T> — the async-wire-call constraint narrows the rule to the surfaces the Phase 6.1 pipeline actually wraps + sidesteps pure in-memory accessors like IHostConnectivityProbe.GetHostStatuses() which would trigger false positives AND (c) the call does NOT sit inside a lambda argument passed to CapabilityInvoker.ExecuteAsync / ExecuteWriteAsync / AlarmSurfaceInvoker.*. The wrapper detection walks up the syntax tree from the call site, finds any enclosing InvocationExpressionSyntax whose method's containing type is one of the wrapper classes, + verifies the call lives transitively inside that invocation's AnonymousFunctionExpressionSyntax argument — a sibling "result = await driver.ReadAsync(...)" followed by a separate invoker.ExecuteAsync(...) call does NOT satisfy the wrapping rule + the analyzer flags it (regression guard in the 5th test). Five xunit-v3 + Shouldly tests at tests/ZB.MOM.WW.OtOpcUa.Analyzers.Tests: direct ReadAsync in server namespace trips; wrapped ReadAsync inside CapabilityInvoker.ExecuteAsync lambda passes; direct WriteAsync trips; direct DiscoverAsync trips; sneaky pattern — read outside the lambda + ExecuteAsync with unrelated lambda nearby — still trips. Hand-rolled test harness compiles a stub-plus-user snippet via CSharpCompilation.WithAnalyzers + runs GetAnalyzerDiagnosticsAsync directly, deliberately avoiding Microsoft.CodeAnalysis.CSharp.Analyzer.Testing.XUnit because that package pins to xunit v2 + this repo is on xunit.v3 everywhere else. RS2008 release-tracking noise suppressed by adding AnalyzerReleases.Shipped.md + AnalyzerReleases.Unshipped.md as AdditionalFiles, which is the canonical Roslyn-analyzer hygiene path. Analyzer DLL referenced from Server.csproj via ProjectReference with OutputItemType=Analyzer + ReferenceOutputAssembly=false — the DLL ships as a compiler plugin, not a runtime dependency. Server build validates clean: the analyzer activates on every Server file but finds zero violations, which confirms the Phase 6.1 wrapping work done in prior PRs is complete + the analyzer is now the regression guard preventing the next new capability surface from being added raw. slnx updated with both the src + tests project entries. Full solution build clean, analyzer suite 5/5 passing.

ZB.MOM.WW.OtOpcUa.Client.CLI.Tests

Client rename residuals: lmxopcua-cli → otopcua-cli + LmxOpcUaClient → OtOpcUaClient with migration shim. Closes task #208 (the executable-name + LocalAppData-folder slice that was called out in Client.CLI.md / Client.UI.md as a deliberately-deferred residual of the Phase 0 rename). Six source references flipped to the canonical OtOpcUaClient spelling: Program.cs CliFx executable name + description (lmxopcua-cli → otopcua-cli), DefaultApplicationConfigurationFactory.cs ApplicationName + ApplicationUri (LmxOpcUaClient + urn:localhost:LmxOpcUaClient → OtOpcUaClient + urn:localhost:OtOpcUaClient), OpcUaClientService.CreateSessionAsync session-name arg, ConnectionSettings.CertificateStorePath default, MainWindowViewModel.CertificateStorePath default, JsonSettingsService.SettingsDir. Two consuming tests (ConnectionSettingsTests + MainWindowViewModelTests) updated to assert the new canonical name. New ClientStoragePaths static helper at src/ZB.MOM.WW.OtOpcUa.Client.Shared/ClientStoragePaths.cs is the migration shim — single entry point for the PKI root + pki subpath, runs a one-shot legacy-folder probe on first resolution: if {LocalAppData}/LmxOpcUaClient/ exists + {LocalAppData}/OtOpcUaClient/ does not, Directory.Move renames it in place (atomic on NTFS within the same volume) so trusted server certs + saved connection settings persist across the rename without operator action. Idempotent per-process via a Lock-guarded _migrationChecked flag so repeated CertificateStorePath getter calls on the hot path pay no IO cost beyond the first. Fresh-install path (neither folder exists) + already-migrated path (only canonical exists) + manual-override path (both exist — developer has set up something explicit) are all no-ops that leave state alone. IOException on the Directory.Move is swallowed + logged as a false return so a concurrent peer process losing the race doesn't crash the consumer; the losing process falls back to whatever state exists. Five new ClientStoragePathsTests assert: GetRoot ends with canonical name under LocalAppData, GetPkiPath nests pki under root, CanonicalFolderName is OtOpcUaClient, LegacyFolderName is LmxOpcUaClient (the migration contract — a typo here would leak the legacy folder past the shim), repeat invocation returns false after first-touch arms the in-process guard. Doc-side residual-explanation notes in docs/Client.CLI.md + docs/Client.UI.md are dropped now that the rename is real; replaced with a short "pre-#208 dev boxes migrate automatically on first launch" note that points at ClientStoragePaths. Sample CLI invocations in Client.CLI.md updated via sed from lmxopcua-cli to otopcua-cli across every command block (14 replacements). Pre-existing staleness in SubscribeCommandTests.Execute_PrintsSubscriptionMessage surfaced during the test run — the CLI's subscribe command has long since switched to an aggregate "Subscribed to {count}/{total} nodes (interval: ...)" output format but the test still asserted the original single-node form. Updated the assertion to match current output + added a comment explaining the change; this is unrelated to the rename but was blocking a green Client.CLI.Tests run. Full solution build 0 errors; Client.Shared.Tests 136/136 + 5 new shim tests passing; Client.UI.Tests 98/98; Client.CLI.Tests 52/52 (was 51/52 before the subscribe-test fix).

2026-04-20 19:22:45 -04:00

ZB.MOM.WW.OtOpcUa.Core.Abstractions.Tests

AB CIP PR 1 — extract shared PollGroupEngine into Core.Abstractions so the AB CIP driver (and any other poll-based driver — S7, FOCAS, AB Legacy) can reuse the subscription loop instead of reimplementing it. Behaviour-preserving refactor of ModbusDriver: SubscriptionState + PollLoopAsync + PollOnceAsync + ModbusSubscriptionHandle lifted verbatim into a new PollGroupEngine class, ModbusDriver's ISubscribable surface now delegates Subscribe/Unsubscribe into the engine and ShutdownAsync calls engine DisposeAsync. Interval floor (100 ms default) becomes a PollGroupEngine constructor knob so per-driver tuning is possible without re-shipping the loop. Initial-data push semantics preserved via forceRaise=true on the first poll. Exception-tolerant loop preserved — reader throws are swallowed, loop continues, driver's health surface remains the single reporting path. Placement in Core.Abstractions (not Core) because driver projects only reference Core.Abstractions by convention (matches OpcUaClient / Modbus / S7 csproj shape); putting the engine in Core would drag EF Core + Serilog + Polly into every driver. Module has no new dependencies beyond System.Collections.Concurrent + System.Threading, so Core.Abstractions stays lightweight. Modbus ctor converted from primary to explicit so the engine field can capture this for the reader + on-change bridge. All 177 ModbusDriver.Tests pass unmodified (Modbus subscription suite, probe suite, cap suite, exception mapper, reconnect, TCP). 10 new direct engine tests in Core.Abstractions.Tests covering: initial force-raise, unchanged-value single-raise, change-between-polls, unsubscribe halts loop, interval-floor clamp, independent subscriptions, reader-exception tolerance, unknown-handle returns false, ActiveSubscriptionCount lifecycle, DisposeAsync cancels all. No changes to driver-specs.md nor to the server Hosting layer — engine is a pure internal building block at this stage. Unblocks AB CIP PR 7 (ISubscribable consumes the engine); also sets up S7 + FOCAS to drop their own poll loops when they re-base.

Phase 7 Stream A.3 — ScriptLoggerFactory + ScriptLogCompanionSink. Third of 3 increments closing out Stream A. Adds the Serilog plumbing that ties script-emitted log events to the dedicated scripts-*.log rolling sink with structured-property filtering AND forwards script Error+ events to the main opcua-*.log at Warning level so operators see script failures in the primary log without drowning it in Debug/Info script chatter. Both pieces are library-level building blocks — the actual file-sink + logger composition at server startup happens in Stream F (Admin UI) / Stream G (address-space wiring). This PR ships the reusable factory + sink + tests so any consumer can wire them up without rediscovering the structured-property contract.

AB CIP Logix Emulate golden-box tier — scaffold the code + docs so the L5X + Emulate PC drop in without fixture-code changes. Closes the initial design question the user raised; the actual Emulate-side work (author project, commit L5X, install Emulate on the dev box) is tracked as #223 . Scaffolding ships everything that doesn't need the live Emulate instance: tier-gated test classes that skip cleanly when AB_SERVER_PROFILE is unset, the profile gate helper, the LogixProject/README.md documenting the exact project state the tests expect, the fixture coverage doc's new §Logix Emulate tier section with the when-to-trust table extended from 3 columns to 4, and the dev-environment.md integration-host row.

FOCAS Tier-C PR A — Driver.FOCAS.Shared MessagePack IPC contracts. First PR of the 5-PR #220 split (isolation plan at docs/v2/implementation/focas-isolation-plan.md). Adds a new netstandard2.0 project consumable by both the .NET 10 Proxy and the future .NET 4.8 x86 Host, carrying every wire DTO the Proxy <-> Host pair will exchange: Hello/HelloAck + Heartbeat/HeartbeatAck + ErrorResponse for session negotiation (shared-secret + protocol major/minor mirroring Galaxy.Shared); OpenSessionRequest/Response + CloseSessionRequest carrying the declared FocasCncSeries so the Host picks up the pre-flight matrix; FocasAddressDto + FocasDataTypeCode for wire-compatible serialization of parsed addresses (0=Pmc/1=Param/2=Macro matches FocasAreaKind enum order so both sides cast (int)); ReadRequest/Response + WriteRequest/Response with MessagePack-serialized boxed values tagged by FocasDataTypeCode; PmcBitWriteRequest/Response as a first-class RMW operation so the critical section stays Host-side; Subscribe/Unsubscribe/OnDataChangeNotification for poll-loop-pushes-deltas model (FOCAS has no CNC-initiated callbacks); Probe + RuntimeStatusChange + Recycle surface for Tier-C supervision. Framing is [4-byte BE length][1-byte kind][body] with 16 MiB body cap matching Galaxy; FocasMessageKind byte values align with Galaxy ranges so an operator reading a hex dump doesn't have to context-switch. FrameReader/FrameWriter ported from Galaxy.Shared with thread-safe concurrent-write serialization. 24 new unit tests: 18 per-DTO round-trip tests covering every field + 6 framing tests (single-frame round-trip, clean-EOF returns null, oversized-length rejection, mid-frame EOF throws, 20-way concurrent-write ordering preserved, MessageKind byte values locked as wire-stable). No driver changes; existing 165 FOCAS unit tests still pass unchanged. PR B (Host skeleton) goes next.

Modbus exception-injection profile — closes the end-to-end test gap for exception codes 0x01/0x03/0x04/0x05/0x06/0x0A/0x0B. pymodbus simulator naturally emits only 0x02 (Illegal Data Address on reads outside configured ranges) + 0x03 (Illegal Data Value on over-length); the driver's MapModbusExceptionToStatus table translates eight codes, but only 0x02 had integration-level coverage (via DL205's unmapped-register test). Unit tests lock the translation function in isolation but an integration test was missing for everything else. This PR lands wire-level coverage for the remaining seven codes without depending on device-specific quirks to naturally produce them.

ZB.MOM.WW.OtOpcUa.Driver.Modbus.Tests

RMW pass 1 — Modbus BitInRegister + FOCAS PMC Bit write paths. First half of task #181 — the two drivers where read-modify-write is a clean protocol-level insertion (Modbus FC03/FC06 round-trip + FOCAS pmc_rdpmcrng / pmc_wrpmcrng round-trip). Per-driver SemaphoreSlim registry keyed on the parent word address serialises concurrent bit writes so two writers targeting different bits in the same word don't lose one another's update. Modbus — ModbusDriver gains WriteBitInRegisterAsync + _rmwLocks ConcurrentDictionary. WriteOneAsync routes BitInRegister (HoldingRegisters region only) through RMW ahead of the normal encode path. Read uses FC03 Read Holding Registers for 1 register at tag.Address, bit-op on the returned ushort via (current | 1<<bit) for set / (current & ~(1<<bit)) for clear, write back via FC06 Write Single Register. Per-address lock prevents concurrent bit writes to the same register from racing. Rejects out-of-range bits (0-15) with InvalidOperationException. EncodeRegister's BitInRegister branch repurposed as a defensive guard — if a non-RMW caller ever reaches it, throw so an unintended bypass stays loud rather than silently clobbering. FOCAS — FwlibFocasClient gains WritePmcBitAsync + _rmwLocks keyed on {addrType}:{byteAddr}. Driver-layer WriteAsync routes Bit writes with a bitIndex through the new path; other Pmc writes still hit the direct pmc_wrpmcrng path. RMW uses cnc_rdpmcrng + Byte dataType to grab the parent byte, bit-op with (current | 1<<bit) or (current & ~(1<<bit)), cnc_wrpmcrng to write back. Rejects out-of-range bits (0-7, FOCAS PMC bytes are 8-bit) with InvalidOperationException. EncodePmcValue's Bit branch now treats a no-bitIndex case as whole-byte boolean (non-zero / zero); bitIndex-present writes never hit this path because they dispatch to WritePmcBitAsync upstream. Tests — 5 new ModbusBitRmwTests + 4 new FocasPmcBitRmwTests + 1 renamed pre-existing test each covering — bit set preserves other bits, bit clear preserves other bits, concurrent bit writes to same word/byte compose correctly (8-parallel stress), bit writes on different parent words proceed without contention (4-parallel), sequential bit sets compose into 0xFF after all 8. Fake PmcRmwFake in FOCAS tests simulates the PMC byte storage + surfaces it through the IFocasClient contract so the test asserts driver-level behavior without needing Fwlib32.dll. FwlibNativeHelperTests.EncodePmcValue_Bit_throws_NotSupported_for_RMW_gap replaced with EncodePmcValue_Bit_without_bit_index_writes_byte_boolean reflecting the new behavior. ModbusDataTypeTests.BitInRegister_write_is_not_supported_in_PR24 renamed to BitInRegister_EncodeRegister_still_rejects_direct_calls; the message assertion updated to match the new defensive message. Modbus tests now 182/182, FOCAS tests now 119/119; full solution builds 0 errors; AbCip/AbLegacy/TwinCAT untouched (those get their RMW pass in a follow-up since libplctag bit access may need a parallel parent-word handle). Task #181 stays pending until that second pass lands.

ZB.MOM.WW.OtOpcUa.Driver.OpcUaClient.IntegrationTests

OpcUaClient integration fixture — opc-plc in Docker closes the wire-level gap (#215 ). Closes task #215 . The OpcUaClient driver had the richest capability matrix in the fleet (reads/writes/subscribe/alarms/history across 11 unit-test classes) + zero wire-level coverage; every test mocked the Session surface. opc-plc is Microsoft Industrial IoT's OPC UA PLC simulator — already containerized, already on MCR, pinned to 2.14.10 here. Wins vs the loopback-against-our-own-server option we'd originally scoped: (a) independent cert chain + user-token handling catches interop bugs loopback can't because both endpoints would share our own cert store; (b) pinned image tag fixes the test surface in a way our evolving server wouldn't; (c) the --alm flag opens the door to real IAlarmSource coverage later without building a custom FakeAlarmDriver. Loss vs loopback: both use the OPCFoundation.NetStandard stack internally so bugs common to that stack don't surface — addressed by a follow-up to add open62541/open62541 as a second independent-stack image (tracked). Docker is the fixture launcher — no PowerShell/Python wrapper like Modbus/pymodbus or S7/python-snap7 because opc-plc ships containerized. Docker/docker-compose.yml pins 2.14.10 + maps port 50000 + command flags --pn=50000 --ut --aa --alm; the healthcheck TCP-probes 50000 so docker ps surfaces ready state. Fixture OpcPlcFixture follows the same shape as Snap7ServerFixture + ModbusSimulatorFixture: collection-scoped, parses OPCUA_SIM_ENDPOINT (default opc.tcp://localhost:50000) into host + port, 2-second TCP probe at init, SkipReason records the failure for Assert.Skip. Forced IPv4 on the probe socket for the same reason those two fixtures do — .NET's dual-stack "localhost" resolves IPv6 ::1 first + hangs the full connect timeout when the target binds 0.0.0.0 (IPv4). OpcPlcProfile holds well-known node identifiers opc-plc exposes (ns=3;s=StepUp, FastUInt1, RandomSignedInt32, AlternatingBoolean) + builds OpcUaClientDriverOptions with SecurityPolicy.None + AutoAcceptCertificates=true since opc-plc regenerates its server cert on every container spin-up + there's no meaningful chain to validate against in CI. Three smoke tests covering what the unit suite couldn't reach: (1) Client_connects_and_reads_StepUp_node_through_real_OPC_UA_stack — full Secure Channel + Session + Read on ns=3;s=StepUp (counter that ticks every 1 s); (2) Client_reads_batch_of_varied_types_from_live_simulator — batch Read of UInt32 / Int32 / Boolean to prove typed Variant decoding, with an explicit ShouldBeOfType<bool> assertion on AlternatingBoolean to catch the common "variant gets stringified" regression; (3) Client_subscribe_receives_StepUp_data_changes_from_live_server — real MonitoredItem subscription on FastUInt1 (100 ms cadence) with a SemaphoreSlim gate + 3 s deadline on the first OnDataChange fire, tolerating container warm-up. Driver ran end-to-end against a live 2.14.10 container: all 3 pass; unit suite 78/78 unchanged. Container lifecycle verified (compose up → tests → compose down) clean, no leaked state. Docker/README.md documents install (Docker Desktop already on the dev box per Phase 1 decision #134 ), run (compose up / compose up -d / compose down), endpoint override (OPCUA_SIM_ENDPOINT), what opc-plc advertises with the current command flags, what's tunable via compose-file tweaks (--daa for username auth tests; --fn/--fr/--ft for subscription-stress nodes), known limitation that opc-plc shares the OPCFoundation stack with our driver. OpcUaClient-Test-Fixture.md updated — TL;DR flipped from "there is no integration fixture" to the new reality; "What it actually covers" gains an Integration section listing the three smoke tests. Follow-up the doc flags: add open62541/open62541 as a second image for fully-independent-stack interop coverage; once #219 (server-side IAlarmSource/IHistoryProvider integration tests) lands, re-run the client-side suite against opc-plc's --alm nodes to close the alarm gap from the client side too.

TwinCAT XAR integration fixture — scaffold the code + docs so the Hyper-V VM + .tsproj drop in without fixture-code changes. Mirrors the AB CIP Logix Emulate scaffold shipped in PR #165 : tier-gated smoke tests that skip cleanly when the VM isn't reachable, a project README documenting exactly what the XAR needs to run, fixture-coverage doc promoting TwinCAT from "no integration fixture" to "scaffolded + needs operational setup". The actual Beckhoff-side work (provision VM, install XAR, author tsproj, rotate 7-day trial) lives in #221 + the new TwinCatProject/README.md walkthrough.
