From 25c1b3eeac21d67d29070704cdd2996e6b68f9d7 Mon Sep 17 00:00:00 2001 From: gonzaloriestra <14979109+gonzaloriestra@users.noreply.github.com> Date: Mon, 18 May 2026 00:53:19 +0000 Subject: [PATCH] [Tests] Remove filesystem mocks in bundle-ui-step.test.ts Refactor executeBundleUIStep tests to use real temporary directories instead of global filesystem mocks. This ensures tests verify actual file operations and handle path resolution nuances correctly. --- .jules/tester.md | 4 + .../build/steps/bundle-ui-step.test.ts | 94 +++++++++++++------ 2 files changed, 67 insertions(+), 31 deletions(-) create mode 100644 .jules/tester.md diff --git a/.jules/tester.md b/.jules/tester.md new file mode 100644 index 00000000000..848c235367c --- /dev/null +++ b/.jules/tester.md @@ -0,0 +1,4 @@ +## 2026-05-18 - [Replace FS mocks with real temp dirs in bundle-ui-step.test.ts] +**Gap:** The test was using `vi.mock('@shopify/cli-kit/node/fs')`, which prevents verifying actual filesystem side effects and can lead to implementation-coupled tests. +**Learning:** Functions like `resolvePath` and `dirname` behave differently on real paths compared to mocked strings, especially when dealing with relative segments like `./`. Using real temp dirs caught these nuances. +**Action:** Always prefer `inTemporaryDirectory` and real FS utilities (`mkdir`, `writeFile`, `fileExists`) over global FS mocks. diff --git a/packages/app/src/cli/services/build/steps/bundle-ui-step.test.ts b/packages/app/src/cli/services/build/steps/bundle-ui-step.test.ts index 1a7a7a0cddf..a722d6f9eec 100644 --- a/packages/app/src/cli/services/build/steps/bundle-ui-step.test.ts +++ b/packages/app/src/cli/services/build/steps/bundle-ui-step.test.ts @@ -4,9 +4,9 @@ import * as buildExtension from '../extension.js' import {BundleUIStep, BuildContext} from '../client-steps.js' import {ExtensionInstance} from '../../../models/extensions/extension-instance.js' import {describe, expect, test, vi, beforeEach} from 'vitest' -import * as fs from '@shopify/cli-kit/node/fs' +import {inTemporaryDirectory, mkdir, writeFile, fileExists} from '@shopify/cli-kit/node/fs' +import {joinPath} from '@shopify/cli-kit/node/path' -vi.mock('@shopify/cli-kit/node/fs') vi.mock('../extension.js') vi.mock('./include-assets/generate-manifest.js') @@ -38,44 +38,76 @@ describe('executeBundleUIStep', () => { } test('copies when local and bundle output directories differ', async () => { -
