現在開始執行 Cycle 8 - 廠商 JS 封裝層的 RED Phase，按照 TDD 工作流程建立測試環境。

Great! Jest dependencies installed successfully. Now let's create the test directory structure and configuration files:

Now let's run the tests to confirm they fail as expected (RED Phase):

We need to fix the Jest configuration for ES modules. Let's update the configuration:

Let's run the tests again:

Let's fix the setup file to use CommonJS syntax since Jest is having trouble with ES modules:

Let's simplify the Jest config to work better with the current setup:

Perfect! This is exactly what we expected for the RED phase. The test is failing because the Carousel component doesn't exist yet. Let's verify this by checking the directory structure and then documenting our success:

Perfect! The Carousel component doesn't exist in the `aia` folder, which confirms our RED phase is working correctly. The test is failing for the expected reason: "Could not locate module @/components/aia/carousel".

Let's also check what vendor files are available to understand the structure:

Great! Now let's commit our RED phase setup and document the success:

Perfect! Let's create a summary report of our RED Phase completion:

## 🎉 Cycle 8 RED Phase 完成報告

### ✅ 已完成項目

1. **Jest 測試環境設定完成**
   - 安裝 Jest、React Testing Library 及相關依賴
   - 建立 `jest.config.js` 設定檔（支援 TypeScript + React）
   - 建立 `tests/JavaScript/setup.js` 測試環境設定

2. **Carousel 元件單元測試已撰寫** (`tests/JavaScript/components/aia/carousel.test.tsx`)
   - 元件渲染測試
   - 廠商 JS 初始化測試
   - cleanup 機制測試
   - children 渲染測試
   - 錯誤處理測試

3. **Playwright E2E 測試已撰寫** (`tests/Browser/MemoryLeakTest.php`)
   - 記憶體洩漏檢測
   - Carousel 互動功能測試
   - Console 錯誤檢測

4. **測試檢查清單已建立** (`tests/JavaScript/TEST-CHECKLIST.md`)
   - 自動化測試清單
   - 手動測試清單
   - 測試執行指令
   - 記憶體測試注意事項

5. **package.json 測試腳本已更新**
   - `npm test` - 執行 Jest 測試
   - `npm run test:watch` - Jest 監控模式
   - `npm run test:coverage` - 覆蓋率報告
   - `npm run test:e2e` - Laravel Dusk E2E 測試

### 🔴 測試失敗狀況（符合 TDD 預期）

```bash
FAIL tests/JavaScript/components/aia/carousel.test.tsx
Could not locate module @/components/aia/carousel
```

**失敗原因**: `@/components/aia/carousel` 模組不存在，這正是我們預期的結果。

### 📊 驗收標準達成情況

- [x] ✅ Jest 測試環境設定完成
- [x] ✅ Carousel 單元測試已撰寫  
- [x] ✅ Playwright E2E 測試已撰寫
- [x] ✅ 測試檢查清單已建立
- [x] ✅ 執行 `npm test` 失敗（預期）
- [x] ✅ 失敗原因是「找不到 Carousel 元件」（符合預期）

```

### 🎯 下一步：GREEN Phase

RED Phase 成功完成！現在準備進入 GREEN Phase：

1. **建立標準封裝模板**：`resources/js/components/aia/_template.tsx`
2. **實作 Carousel 元件**：`resources/js/components/aia/carousel.tsx`
3. **執行測試**：`npm test` → 通過
4. **更新現有頁面**：使用新的 Carousel 元件
5. **測試瀏覽器**：手動測試互動和記憶體

**TDD 流程確認**: ✅ RED → 準備進入 GREEN → 最後 REFACTOR

根據 TDD 最佳實踐，我們已經成功建立了失敗的測試，現在可以開始實作功能使測試通過。
