+# UI测试迁移指南
+
+## 概述
+
+本文档说明了UI测试从旧版本迁移到新React前端的主要变更。
+
+## 主要变更
+
+### 1. 输出目录变更
+
+**旧版本:**
+```
+dockerapp/test_playlists/{playlist_name}/
+```
+
+**新版本:**
+```
+output_playlists/{playlist_name}/
+```
+
+### 2. 服务器端口变更
+
+**旧版本:**
+- 测试服务器: `http://localhost:8000`
+
+**新版本:**
+- Docker映射端口: `http://localhost:8888`
+- 容器内端口: `8080`
+
+### 3. UI架构变更
+
+**旧版本:**
+- 传统的HTML模板 (Jinja2)
+- 选择器: `#addRuleBtn`, `select[name='mode']`, `input[name='pattern']`
+
+**新版本:**
+- React + TypeScript + Vite
+- 策略选择器: 中间位置的圆形按钮下拉菜单
+- 正则规则在StrategySelector组件中管理
+- 选择器: `button[title='Add Rule']`, `input[placeholder='Regex Pattern']`
+
+### 4. 测试文件修改
+
+#### `conftest_ui.py`
+- 更新BASE_URL为`http://localhost:8888`
+- 修改server fixture为仅验证服务器运行状态
+- 要求手动启动Docker Compose服务
+
+#### `test_ui_case_mix.py`
+- 添加`SyncStrategy`枚举类
+- 实现`_open_strategy_selector()`和`_close_strategy_selector()`辅助函数
+- 更新策略选择逻辑以适配React UI
+- 更新正则规则添加逻辑
+- 修改输出路径为`output_playlists/case_mix/`
+
+#### `test_ui_regex_rules.py`
+- 完全重写所有测试用例以适配React UI
+- 添加辅助方法`_open_strategy_selector()`和`_close_strategy_selector()`
+- 更新所有选择器以匹配新UI结构
+- 适配Toast通知验证
+
+## 运行测试
+
+### 前提条件
+
+1. **启动Docker Compose服务:**
+   ```powershell
+   docker compose up -d
+   ```
+
+2. **验证服务运行:**
+   ```powershell
+   # 在浏览器中访问
+   # http://localhost:8888
+   ```
+
+3. **安装测试依赖:**
+   ```powershell
+   pip install pytest-playwright requests
+   playwright install
+   ```
+
+### 运行测试
+
+**显示浏览器模式 (调试用):**
+```powershell
+pytest tests/test_ui_case_mix.py --headed
+pytest tests/test_ui_regex_rules.py --headed
+```
+
+**无头模式 (CI/CD):**
+```powershell
+pytest tests/test_ui_case_mix.py
+pytest tests/test_ui_regex_rules.py
+```
+
+**运行所有UI测试:**
+```powershell
+pytest tests/test_ui_*.py --headed
+```
+
+## 新UI元素定位
+
+### 策略选择器
+
+- **触发按钮:** `button` with SVG icon (圆形按钮)
+- **下拉菜单:** `div.absolute.top-14`
+- **策略选项:** `div:has-text('{strategy_label}')` with SVG
+
+### 正则规则
+
+- **添加按钮:** `button[title='Add Rule']` 或 `button:has-text('Add Rule')`
+- **删除按钮:** `button[title='Delete Rule']`
+- **模式输入:** `input[placeholder='Regex Pattern']`
+- **替换输入:** `input[placeholder='Replacement']`
+- **保存按钮:** `button:has-text('Save Changes')`
+- **重置按钮:** `button:has-text('Revert')`
+
+### Toast通知
+
+- **成功通知:** `div:has-text('Regex preprocessing rules have been saved')`
+- **策略保存:** `div:has-text('Selected strategy "{label}" has been saved')`
+
+## 策略映射
+
+| UI显示名称 | SyncStrategy枚举 | 旧版mode值 | 预期输出文件 |
+|-----------|-----------------|-----------|-------------|
+| Local Overwrite | LOCAL_OVERWRITE | local_force | case_mix_local_force.m3u |
+| Cloud Overwrite | CLOUD_OVERWRITE | remote_force | case_mix_remote_force.m3u |
+| Two-way Merge (Local Priority) | MERGE_LOCAL | merge_local_primary | case_mix_merge_local_primary.m3u |
+| Two-way Merge (Cloud Priority) | MERGE_CLOUD | merge_remote_primary | case_mix_merge_remote_primary.m3u |
+
+## 已知问题和注意事项
+
+1. **同步触发:** 新UI需要通过API显式触发同步操作。测试中使用 `POST /api/sync` 端点:
+   ```python
+   import requests
+   sync_response = requests.post(
+       f"{BASE_URL}/api/sync",
+       json={"mode": None}  # 使用当前配置的策略
+   )
+   ```
+
+2. **Toast通知:** Toast通知有动画效果，需要适当的等待时间 (300-500ms)。
+
+3. **下拉菜单:** 策略选择器的下拉菜单需要通过ESC键关闭，或点击外部区域。
+
+4. **测试隔离:** 每个测试应该清理自己添加的规则，避免影响后续测试。
+
+## 故障排除
+
+### 服务器未运行
+```
+错误: 无法连接到测试服务器: http://localhost:8888
+解决: docker compose up -d
+```
+
+### 元素未找到
+```
+错误: Timeout waiting for locator('button[title="Add Rule"]')
+解决: 检查策略选择器是否已打开，确保调用了_open_strategy_selector()
+```
+
+### 输出文件未生成
+```
+错误: AssertionError: {strategy_label}: local_result.m3u8 未生成
+解决: 
+1. 检查output_playlists/case_mix/目录是否存在
+2. 验证Docker volume映射配置
+3. 检查后端日志: docker compose logs
+```
+
+## 更新日期
+
+2024-11-29 - 初始迁移完成
