-### 配置容器时区
-
-本项目支持通过 `docker-compose.yml` 的环境变量 `TZ` 配置容器运行时区（需要使用有效的 IANA 时区名，例如 `Asia/Shanghai`、`UTC`、`America/New_York`）。
-
-- 临时指定（当前终端会话生效）：
-
-```bash
-TZ=UTC docker compose up --build
-```
-
-- 或在项目根目录创建 `.env`：
-
-```env
-TZ=Asia/Shanghai
-```
-
 - 默认会以 `--reload` 模式启动，监听本地 8080 端口，可在浏览器访问 `http://localhost:8080`。
 - 通过 `./app/config.json` 保存的 Plex 配置信息会在主机和容器间共享，便于调试时保留登录 token 等数据。
 - 如需自定义端口或其他参数，可在 `docker-compose.yml` 中调整。

+r"C:\Music\track.mp3" → r"D:\Audio\track.mp3"
+```
+
+### 捕获组
+```python
+rules = [{"pattern": r"/(\d+)/", "replacement": r"/year-\1/"}]
+"/music/2024/track.mp3" → "/music/year-2024/track.mp3"
+```
+
+### NAS 路径转换（真实场景）
+```python
+rules = [
+    {"pattern": r"\\\\nas\\Music", "replacement": r"N:\\Music"},

+```
+
+## 🔧 配置选项
+
+### pytest.ini 配置
+
+```ini
+[pytest]
+# Playwright 配置
+addopts = 
+    --browser=chromium
+    --headed
+    --slowmo=100
+```
+
+### 环境变量
+
+```bash
+# 设置测试服务器地址
+export TEST_SERVER_URL="http://localhost:8000"
+
+# 设置浏览器类型
+export BROWSER=chromium  # 或 firefox, webkit
+```
+
+## 🐛 调试技巧
+
+### 1. 使用有头模式
+
+```bash
+pytest tests/test_ui_regex_rules.py --headed
+```
+
+### 2. 使用慢速模式
+
+```bash
+pytest tests/test_ui_regex_rules.py --headed --slowmo=1000
+```
+
+### 3. 截图调试
+
+在测试中添加截图:
+
+```python
+def test_something(page: Page):
+    page.screenshot(path="debug_screenshot.png")
+```
+
+### 4. 使用 Playwright Inspector
+
+```bash
+# 启动调试模式
+PWDEBUG=1 pytest tests/test_ui_regex_rules.py::test_add_single_rule
+```
+
+### 5. 查看追踪
+
+```python
+# 在 conftest.py 中添加
+@pytest.fixture
+def context(browser):
+    context = browser.new_context()
+    context.tracing.start(screenshots=True, snapshots=True)
+    yield context
+    context.tracing.stop(path="trace.zip")
+```
+
+然后查看:
+```bash
+playwright show-trace trace.zip
+```
+
+## 📝 编写新的 UI 测试
+
+### 基本模板
+
+```python
+def test_my_feature(page: Page):
+    """测试我的功能"""
+    # 1. 导航到页面
+    page.goto("http://localhost:8000")
+    
+    # 2. 与元素交互
+    button = page.locator("#myButton")
+    button.click()
+    
+    # 3. 验证结果
+    expect(page.locator("#result")).to_have_text("Success")
+```
+
+### 等待策略
+
+```python
+# 等待元素可见
+page.wait_for_selector("#element", state="visible")
+
+# 等待网络空闲
+page.wait_for_load_state("networkidle")
+
+# 等待特定时间（尽量避免）
+page.wait_for_timeout(1000)  # 1 秒
+```
+
+### 选择器策略
+
+```python
+# 推荐: 使用 data-testid
+page.locator("[data-testid='add-rule-btn']")
+
+# 通过文本
+page.locator("button:has-text('保存规则')")
+
+# 通过 ID
+page.locator("#addRuleBtn")
+
+# 通过 CSS 类
+page.locator(".rule-row")
+
+# 组合选择器
+page.locator(".rule-row input[name='pattern']")
+```
+
+## 🎨 最佳实践
+
+### 1. 使用 Page Object 模式
+
+```python
+class RulesPage:
+    def __init__(self, page: Page):
+        self.page = page
+        self.add_button = page.locator("#addRuleBtn")
+        self.save_button = page.locator("button:has-text('保存规则')")
+    
+    def add_rule(self, pattern: str, replacement: str):
+        self.add_button.click()
+        self.page.wait_for_timeout(100)
+        
+        patterns = self.page.locator("input[name='pattern']")
+        replacements = self.page.locator("input[name='replacement']")
+        
+        patterns.last.fill(pattern)
+        replacements.last.fill(replacement)
+    
+    def save(self):
+        self.save_button.click()
+        self.page.wait_for_load_state("networkidle")
+
+# 使用
+def test_with_page_object(page: Page):
+    rules_page = RulesPage(page)
+    rules_page.add_rule(r"/old/", r"/new/")
+    rules_page.save()
+```
+
+### 2. 使用 Fixtures 清理状态
+
+```python
+@pytest.fixture
+def clean_rules(page: Page):
+    """清除所有规则"""
+    page.goto("http://localhost:8000")
+    while page.locator(".rule-row").count() > 0:
+        page.locator(".rule-row button[title='删除此规则']").first.click()
+        page.wait_for_timeout(50)
+    yield
+```
+
+### 3. 避免硬编码等待时间
+
+```python
+# ❌ 不好
+page.wait_for_timeout(2000)
+
+# ✅ 好
+page.wait_for_selector("#element", state="visible")
+page.wait_for_load_state("networkidle")
+```
+
+### 4. 使用断言而非 if 判断
+
+```python
+# ❌ 不好
+assert page.locator("#element").count() > 0
+
+# ✅ 好
+expect(page.locator("#element")).to_be_visible()
+```
+
+## 🔄 CI/CD 集成
+
+### GitHub Actions 示例
+
+```yaml
+name: UI Tests
+
+on: [push, pull_request]
+
+jobs:
+  ui-tests:
+    runs-on: ubuntu-latest

+
+## 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
+```
