From be7645623c53aafb0bc8cbca3d5094a99505cca5 Mon Sep 17 00:00:00 2001 From: gonzaloriestra <14979109+gonzaloriestra@users.noreply.github.com> Date: Sat, 23 May 2026 00:13:31 +0000 Subject: [PATCH 1/2] [Tests] Remove filesystem mocks in dev-override.test.ts Refactor `packages/theme/src/cli/services/dev-override.test.ts` to remove global `vi.mock('@shopify/cli-kit/node/fs')` and use real filesystem operations in temporary directories.
