New project tests/ZB.MOM.WW.OtOpcUa.Driver.TwinCAT.IntegrationTests/ with four pieces. TwinCATXarFixture — TCP probe against the ADS-over-TCP port 48898 on the host from TWINCAT_TARGET_HOST env var, requires TWINCAT_TARGET_NETID for the target AmsNetId, optional TWINCAT_TARGET_PORT for runtime 2+ (default 851 = PLC runtime 1). Doesn't own a lifecycle — XAR can't run in Docker because it bypasses the Windows kernel scheduler to hit real-time cycles, so the VM stays operator-managed. Explicit skip reasons surface the setup steps (start VM, set env vars, reactivate trial license) instead of a confusing hang. TwinCATFactAttribute + TwinCATTheoryAttribute — xunit skip gate matching AbServerFactAttribute / OpcPlcCollection patterns. TwinCAT3SmokeTests — three smoke tests through the real AdsTwinCATClient + real ADS over TCP. Driver_reads_seeded_DINT_through_real_ADS reads GVL_Fixture.nCounter, asserts >= 1234 (MAIN increments every cycle so an exact match would race). Driver_write_then_read_round_trip_on_scratch_REAL writes 42.5 to GVL_Fixture.rSetpoint + reads back, catches the ADS write path regression that unit tests can't see. Driver_subscribe_receives_native_ADS_notifications_on_counter_changes validates the #189 native-notification path end-to-end — AddDeviceNotification fires OnDataChange at the PLC cycle boundary, the test observes one firing within 3 s. All three gated on TWINCAT_TARGET_HOST + NETID; skip via TwinCATFactAttribute when unset, verified in this commit with 3 clean [SKIP] results. TwinCatProject/README.md — the tsproj state the smoke tests depend on. GVL_Fixture with nCounter:DINT:=1234 + rSetpoint:REAL:=0.0 + bFlag:BOOL:=TRUE; MAIN program with the single-line ladder `GVL_Fixture.nCounter := GVL_Fixture.nCounter + 1;`; PlcTask cyclic @ 10 ms priority 20; PLC runtime 1 (AMS port 851). Explains why tsproj over the compiled bootproject (text-diffable, rebuildable, no per-install state). Full XAR VM setup walkthrough — Hyper-V Gen 2 VM, TC3 XAE+XAR install, noting the AmsNetId from the tray icon, bilateral route configuration (VM System Manager → Routes + dev box StaticRoutes.xml), project import, Activate Configuration + Run Mode. License-rotation section walks through two options — scheduled TcActivate.exe /reactivate via Task Scheduler (not officially Beckhoff-supported, reportedly works on current builds) or paid runtime license (~$1k one-time per runtime per CPU). Final section shows the exact env-var recipe + dotnet test command on the dev box. docs/drivers/TwinCAT-Test-Fixture.md — flipped TL;DR from "there is no integration fixture" to "scaffolding lives at tests/..., remaining operational work is VM + tsproj + license rotation". "What the fixture is" gains an Integration section describing the XAR VM target. "What it actually covers" gains an Integration subsection listing the three named smoke tests. Follow-up candidates rewritten — the #1 item used to be "TwinCAT 3 runtime on CI" as a speculative option; now it's concrete "XAR VM live-population" with a link to #221 + the project README for the operational walkthrough. License rotation becomes #2 with both automation paths. Key fixture / config files list adds the three new files + the project README. docs/drivers/README.md coverage-map row updated from "no integration fixture" to "XAR-VM integration scaffolding". Solution file picks up the new tests/ZB.MOM.WW.OtOpcUa.Driver.TwinCAT.IntegrationTests entry alongside the existing TwinCAT.Tests. xunit CollectionDefinition added to TwinCATXarFixture after the first build revealed the [Collection("TwinCATXar")] reference on TwinCAT3SmokeTests had no matching registration. Build 0 errors; 3 skip-clean test outcomes verified. #221 stays open as in_progress until the VM + tsproj land. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
