From 83dc8c837014e53f93e8feaeef418db148c24026 Mon Sep 17 00:00:00 2001 From: Teng Lin Date: Wed, 25 Feb 2026 12:09:55 -0500 Subject: [PATCH 12/33] fix: strengthen promise flush and fix test title in reconnect-policy coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace two Promise.resolve() flushes with four flushPromises() calls imported from src/testing/cli-message-factories.ts; the relaunchStaleSessions chain has multiple async hops (timer → relaunch reject → Promise.allSettled → result iteration → logger.warn) that require more than two microtask turns - Rename idempotency test title to accurately describe the guard that fires: "stop() is idempotent — second call exits early because reconnectTimer is already null" (the reconnectTimer null-check in stop(), not the teardownDomainSubscriptions empty-array guard) - Update inline comment to clarify teardownDomainSubscriptions is not reached on the second stop() call --- .../consumer-gatekeeper-coverage.test.ts | 78 ++----- .../policies/idle-policy-coverage.test.ts | 166 +++----------- .../reconnect-policy-coverage.test.ts | 50 ++--- ...ssion-runtime-commands.integration.test.ts | 126 +++-------- ...-runtime-orchestration.integration.test.ts | 209 +++++------------- 5 files changed, 165 insertions(+), 464 deletions(-) diff --git a/src/core/consumer/consumer-gatekeeper-coverage.test.ts b/src/core/consumer/consumer-gatekeeper-coverage.test.ts index a63dda0..42dc6e6 100644 --- a/src/core/consumer/consumer-gatekeeper-coverage.test.ts +++ b/src/core/consumer/consumer-gatekeeper-coverage.test.ts @@ -32,11 +32,17 @@ function makeIdentity(role: "participant" | "observer" = "participant"): Consume return { userId: "u1", displayName: "Alice", role };

Set this to `50` in `makeDeps` so fake timers can advance past it with `vi.advanceTimersByTime(100)`. - -### makeDeps reuse -Each test file needs its own `makeDeps`. Do not extract to a shared file unless it already exists in `src/testing/`. Prefer keeping test files self-contained. - -### Verifying real reducer effects -These are **integration** tests — they should NOT mock the `sessionReducer`. The reducer runs for real. Spy on `broadcaster.broadcast` / `broadcaster.broadcastToParticipants` to observe effects. Only mock the deps that represent external I/O (backendConnector.sendToBackend, store.persist, etc.). - -### Command interface shapes -Check `src/core/interfaces/runtime-commands.ts` for the exact fields of each inbound command type before writing tests. Key commands: -- `user_message`: `{ type, content, session_id, images?, traceContext? }` -- `queue_message`: `{ type, content, session_id }` -- `update_queued_message`: `{ type, content, session_id }` -- `cancel_queued_message`: `{ type, session_id }` -- `presence_query`: `{ type, session_id }` -- `set_adapter`: `{ type, adapter_name, session_id }` -- `permission_response`: `{ type, request_id, behavior, ... }` -- `slash_command`: `{ type, command, session_id }` From 59639fc291ad627b23fe2c550ddaa1f5797be787 Mon Sep 17 00:00:00 2001 From: Teng Lin Date: Wed, 25 Feb 2026 12:39:24 -0500 Subject: [PATCH 26/33] test: add coverage for prometheus-metrics-collector uncovered branches --- ...metheus-metrics-collector-coverage.test.ts | 65 +++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 src/adapters/prometheus-metrics-collector-coverage.test.ts diff --git a/src/adapters/prometheus-metrics-collector-coverage.test.ts b/src/adapters/prometheus-metrics-collector-coverage.test.ts new file mode 100644 index 0000000..5537a95 --- /dev/null +++ b/src/adapters/prometheus-metrics-collector-coverage.test.ts @@ -0,0 +1,65 @@ +import { describe, expect, it } from "vitest";
