From 4ce67a021200d8b3d8b42e7c51bd25f7414b75b6 Mon Sep 17 00:00:00 2001 From: quality Date: Tue, 6 Oct 2026 04:22:22 -0400 Subject: [PATCH 1/3] test(bundle): drive the sweep cron's empty-window, failed-listing and blunderbuss-freshness arms through dist/index.js __tests__/bundle/sweepArms.test.ts runs the schedule sweep job against the fake GitHub for the arms of src/cronJobs/sweep.ts that no bundle test reached: the zero-candidate return, the pulls.list failure, and requestReviewersIfFresh's three early returns (opened before the window, draft or already requested, already reviewed), plus the pass-through case. npm run test:coverage:e2e on main @ 3fc21f2: sweep.ts 67/76 -> 75/76 statements; only the enqueued arm (line 75) remains.
