From d48099f0d023d652c99a9e9c96c96305acb02dda Mon Sep 17 00:00:00 2001 From: Joseph Doherty Date: Sun, 24 May 2026 03:20:40 -0400 Subject: [PATCH] Resolve Tests-025..026 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tests-025 (Conventions): Extracted the previously-duplicated NullDashboardEventBroadcaster into TestSupport/NullDashboardEventBroadcaster.cs (singleton Instance, private ctor). The two nested copies in EventStreamServiceTests and GatewayEndToEndFakeWorkerSmokeTests were removed; both files now use the shared type via 'using ZB.MOM.WW.MxGateway.Tests.TestSupport;'. The Server-041 regression test's ThrowingDashboardEventBroadcaster is intentionally left nested — single-file usage doesn't warrant promotion to TestSupport. The third copy in IntegrationTests/WorkerLiveMxAccessSmokeTests was handled by IntegrationTests-024 in its own commit. Tests-026 (Testing coverage): Added a new RecordingDashboardEventBroadcaster test double in TestSupport — a thread-safe (ConcurrentQueue) recorder. New fixture StreamEventsAsync_PublishesEachEventToDashboardBroadcaster in EventStreamServiceTests pushes two events through the fake session and asserts the broadcaster received both with the correct sessionId and WorkerSequence. TDD red→green confirmed: the deliberately-wrong "Expected 3, Actual 2" red phase proved the recording fake was actually invoked by the production code path. Verification: 486/486 server tests passing (485 previous + 1 new).

This mirrors the duplication pattern Tests-007 and Tests-021 already consolidated for `TestServerCallContext` / `RecordingServerStreamWriter` / `AllowAllConstraintEnforcer` / `ManualTimeProvider` into `src/MxGateway.Tests/TestSupport/`; the same pattern should apply here. **Recommendation:** Extract `NullDashboardEventBroadcaster` to `src/ZB.MOM.WW.MxGateway.Tests/TestSupport/NullDashboardEventBroadcaster.cs` (or a single `DashboardTestDoubles.cs`), delete both nested copies, and update the two `using`-bearing files to import from `TestSupport`. -**Resolution:** _(empty until closed)_ +**Resolution:** 2026-05-24 — Extracted the shared no-op broadcaster to `src/ZB.MOM.WW.MxGateway.Tests/TestSupport/NullDashboardEventBroadcaster.cs` (single `public sealed` class with the singleton `Instance` field and a private constructor — matches the Tests-007 / Tests-021 consolidation pattern). Deleted both nested duplicates (`EventStreamServiceTests.cs:319-323` and `GatewayEndToEndFakeWorkerSmokeTests.cs:417-421`); the latter already imported `ZB.MOM.WW.MxGateway.Tests.TestSupport` so `NullDashboardEventBroadcaster.Instance` resolves against the shared type. `EventStreamServiceTests.cs` gained a `using ZB.MOM.WW.MxGateway.Tests.TestSupport;`. The integration-tests copy in `src/ZB.MOM.WW.MxGateway.IntegrationTests/WorkerLiveMxAccessSmokeTests.cs` was left alone (different module, per scope). Server-041's `ThrowingDashboardEventBroadcaster` remains nested in `EventStreamServiceTests` (single-file usage, no consolidation needed).

The unit tests inject `NullDashboardEventBroadcaster.Instance`, so the broadcaster invocation is never observed — a regression that silently dropped the `Publish` call (e.g. an `if` accidentally added around it, or removing the broadcaster ctor parameter) would not be caught by any test in this module. The hub-registration tests (`DashboardHubsRegistrationTests`) verify the endpoints exist but not the producer-side hook. **Recommendation:** Add a fixture to `EventStreamServiceTests` named e.g. `StreamEventsAsync_PublishesEachEventToDashboardBroadcaster`: inject a recording fake that captures `(sessionId, mxEvent)` calls, push two events through the fake session, and assert the broadcaster received both with the correct session id and matching `WorkerSequence`.

Added `StreamEventsAsync_PublishesEachEventToDashboardBroadcaster` to `EventStreamServiceTests`: pushes two events (`WorkerSequence` 7 / `OnDataChange` and 8 / `OnWriteComplete`) through the fake session, drains the stream, and asserts the recording broadcaster captured exactly two publishes with the matching `SessionId`, `WorkerSequence`, and `Family` for each. TDD red/green confirmed: a deliberate "expected 3 captures" failed (`Expected: 3, Actual: 2`) before flipping to the correct count; the green run passes deterministically. The fixture would have caught a regression that drops or wraps `dashboardEventBroadcaster.Publish` at `EventStreamService.cs:133`.
