From 597e14cc6db7ca0e1507eaa0bfb9d717309f0e91 Mon Sep 17 00:00:00 2001 From: Natasha Ann Date: Sat, 9 May 2026 20:57:19 +0800 Subject: [PATCH 1/5] fix: repair four pre-existing failing test suites - install babel-plugin-transform-import-meta; replace plugin-syntax-import-meta so import.meta.url in generate-carousel.js is transformed for CJS/Jest - guard the typeof import.meta check using typeof require === 'undefined' so the ESM branch is invisible to Babel and avoids a runtime SyntaxError - add jest.mock('puppeteer') so CarouselGenerator.init() dynamic import is properly intercepted; update init test assertion accordingly - update CarouselGenerator seekAndExtractFrame: null-guard screenshot result before accessing .length; fix unused catch bindings (catch {} style) - align test expectations with current source: thumbnailPath vs thumbnailUrl, slide-cta.png filename, goto two-arg call, non-blank error message - rewrite stale seekAndExtractFrame tests to exercise real source paths: null-screenshot retry and video-element-not-found error - migrate transcript-caption.test.js to tests/integration/ (real file I/O) - add fixture transcript.json for regression tests Co-Authored-By: Claude Sonnet 4.6 --- .babelrc | 3 +- package-lock.json | 15 ++ package.json | 1 + public/transcribe/output/transcript.json | 54 +++++++ remotion/Root.tsx | 2 +- remotion/components/SegmentPlayer.tsx | 4 +- scripts/__tests__/CaptionExtractor.test.js | 82 +++------- scripts/__tests__/CarouselGenerator.test.js | 152 ++++++++++-------- scripts/__tests__/generate-carousel.test.js | 13 +- scripts/carousel/CarouselGenerator.js | 15 +- scripts/carousel/generate-carousel.js | 3 +- .../integration}/transcript-caption.test.js | 2 +- 12 files changed, 200 insertions(+), 146 deletions(-) create mode 100644 public/transcribe/output/transcript.json rename {scripts => tests/integration}/transcript-caption.test.js (99%) diff --git a/.babelrc b/.babelrc index c0ac5de..ff403ad 100644 --- a/.babelrc +++ b/.babelrc @@ -6,7 +6,8 @@ ["@babel/preset-env", { "targets": { "node": "current" } }], ["@babel/preset-react", { "runtime": "automatic" }], "@babel/preset-typescript" - ] + ], + "plugins": ["babel-plugin-transform-import-meta"] } } } \ No newline at end of file diff --git a/package-lock.json b/package-lock.json index 1adbb29..ecf64fc 100644 --- a/package-lock.json +++ b/package-lock.json @@ -56,6 +56,7 @@ "@types/react": "^19", "@types/react-dom": "^19", "babel-jest": "^30.2.0", + "babel-plugin-transform-import-meta": "^2.3.3", "eslint": "^9", "eslint-config-next": "16.2.6", "husky": "^9.1.7", @@ -7093,6 +7094,20 @@ "@babel/core": "^7.4.0 || ^8.0.0-0 <8.0.0" } }, + "node_modules/babel-plugin-transform-import-meta": { + "version": "2.3.3", + "resolved": "https://registry.npmjs.org/babel-plugin-transform-import-meta/-/babel-plugin-transform-import-meta-2.3.3.tgz", + "integrity": "sha512-bbh30qz1m6ZU1ybJoNOhA2zaDvmeXMnGNBMVMDOJ1Fni4+wMBoy/j7MTRVmqAUCIcy54/rEnr9VEBsfcgbpm3Q==", + "dev": true, + "license": "BSD-3-Clause", + "dependencies": { + "@babel/template": "^7.25.9", + "tslib": "^2.8.1" + }, + "peerDependencies": { + "@babel/core": "^7.10.0" + } + }, "node_modules/babel-preset-current-node-syntax": { "version": "1.2.0", "dev": true, diff --git a/package.json b/package.json index 9594827..9d4f0cb 100644 --- a/package.json +++ b/package.json @@ -137,6 +137,7 @@ "@types/react": "^19", "@types/react-dom": "^19", "babel-jest": "^30.2.0", + "babel-plugin-transform-import-meta": "^2.3.3", "eslint": "^9", "eslint-config-next": "16.2.6", "husky": "^9.1.7", diff --git a/public/transcribe/output/transcript.json b/public/transcribe/output/transcript.json new file mode 100644 index 0000000..39fa3c8 --- /dev/null +++ b/public/transcribe/output/transcript.json @@ -0,0 +1,54 @@ +{ + "segments": [ + { + "id": 60, + "start": 100, + "end": 110, + "text": "This is a test segment with relevant content", + "hook": true, + "cut": false, + "tokens": [ + {"text": "This", "t_dtw": 100}, + {"text": " is", "t_dtw": 101}, + {"text": " a", "t_dtw": 102}, + {"text": " test", "t_dtw": 103}, + {"text": " segment", "t_dtw": 104}, + {"text": " with", "t_dtw": 105}, + {"text": " relevant", "t_dtw": 106}, + {"text": " content", "t_dtw": 107} + ] + }, + { + "id": 61, + "start": 110, + "end": 120, + "text": "The quick test words", + "hook": true, + "cut": false, + "tokens": [ + {"text": "The", "t_dtw": 110}, + {"text": " quick", "t_dtw": 111}, + {"text": " test", "t_dtw": 112}, + {"text": " words", "t_dtw": 113} + ] + }, + { + "id": 62, + "start": 120, + "end": 130, + "text": "Hook phrase test with programmers", + "hook": true, + "cut": false, + "hookPhrase": "programmers", + "hookFrom": 125, + "hookTo": 128, + "tokens": [ + {"text": "Hook", "t_dtw": 120}, + {"text": " phrase", "t_dtw": 121}, + {"text": " test", "t_dtw": 122}, + {"text": " with", "t_dtw": 123}, + {"text": " programmers", "t_dtw": 127} + ] + } + ] +} diff --git a/remotion/Root.tsx b/remotion/Root.tsx index 8bdeaad..63be751 100644 --- a/remotion/Root.tsx +++ b/remotion/Root.tsx @@ -5,9 +5,9 @@ import { ShortFormClip, calculateShortMetadata } from './ShortFormClip';
