From 3bea12f5d871217c609bccae76c080b5e8878fa0 Mon Sep 17 00:00:00 2001 From: gsxdsm Date: Wed, 3 Jun 2026 10:48:23 -0700 Subject: [PATCH] test(FN-branch-group): end-to-end planning + mission single-PR flows (U8) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Engine half: real-git E2E covering planning- and mission-sourced groups — members land on the group branch (never main/sibling), completion-gated single PR via injected callback, re-promote idempotency, sync on later landing, abandon→closed, and a self-healing finalize mid-flow staying group-anchored. Core half: real triageFeature stamps the BG- id, member enumeration, and the canonical completion gate flipping on landing. --- .../branch-group-entry-point-e2e.test.ts | 128 ++++++ .../branch-group-single-pr-e2e.test.ts | 393 ++++++++++++++++++ 2 files changed, 521 insertions(+) create mode 100644 packages/core/src/__tests__/branch-group-entry-point-e2e.test.ts create mode 100644 packages/engine/src/__tests__/reliability-interactions/branch-group-single-pr-e2e.test.ts diff --git a/packages/core/src/__tests__/branch-group-entry-point-e2e.test.ts b/packages/core/src/__tests__/branch-group-entry-point-e2e.test.ts new file mode 100644 index 0000000000..1747a4c405 --- /dev/null +++ b/packages/core/src/__tests__/branch-group-entry-point-e2e.test.ts @@ -0,0 +1,128 @@ +import { afterEach, beforeEach, describe, expect, it } from "vitest"; +import { mkdtempSync } from "node:fs"; +import { rm } from "node:fs/promises"; +import { join } from "node:path"; +import { tmpdir } from "node:os"; + +import { TaskStore } from "../store.js"; +import { isBranchGroupComplete } from "../branch-group-completion.js"; + +/** + * U8 (R9): entry-point half of the end-to-end single managed-PR flow. + * + * Composition choice (stated honestly): a single test that drives planning → + * engine → GitHub across the dashboard↔engine↔core package boundaries is + * impractical.
