From aa92ac448ff885d167eeb6c5332367d9527e19c5 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-FE Date: Mon, 11 May 2026 06:23:20 +0000 Subject: [PATCH] fix(canvas/test): isolate ApprovalBanner tests from ActivityTab mock pollution ApprovalBanner.test.tsx was using vi.spyOn(api, "get").mockResolvedValueOnce() which was failing when run after ActivityTab.test.tsx in the full suite: ActivityTab's beforeEach sets a mockResolvedValue([]) default that persisted across ApprovalBanner tests. Fix: remove vi.restoreAllMocks() from afterEach so queued mockResolvedValueOnce values survive between tests. Also fix "POST fails" tests to use vi.mocked(api.post).mockRejectedValueOnce() instead of vi.spyOn(api, "post") to avoid overwriting the beforeEach spy.
