**测试日期:** ${new Date().toLocaleString('zh-CN')}

## 执行摘要

| 指标 | 数值 |
|------|------|
| 通过 | ${passed} |
| 失败 | ${failed} |
| 跳过 | ${skipped} |
| 总计 | ${results.length} |
| 通过率 | ${((passed / results.length) * 100).toFixed(1)}% |

## 详细结果

${results.map(r => `
### ${r.testName}
- **状态:** ${r.status === 'passed' ? '✅ 通过' : r.status === 'failed' ? '❌ 失败' : '⏭️ 跳过'}
- **耗时:** ${r.duration}ms
${r.error ? `- **错误:** ${r.error}` : ''}
${r.screenshot ? `- **截图:** ${r.screenshot}` : ''}
`).join('\n')}

## 测试覆盖范围

### 1. 页面加载与基础功能
- [x] 首页加载
- [x] 控制台错误检查
- [x] 响应式布局

### 2. 聊天功能
- [x] 聊天界面渲染
- [x] 输入框交互
- [x] 消息发送(模拟)

### 3. 导航与路由
- [x] 侧边栏导航
- [x] 页面切换
- [x] 路由状态

### 4. UI组件
- [x] 按钮和交互元素
- [x] 表单输入
- [x] 模态框/对话框

### 5. 状态管理
- [x] Store初始化
- [x] 状态更新

## 发现的问题

${results.filter(r => r.status === 'failed').map(r => `- **${r.testName}**: ${r.error}`).join('\n') || '未发现严重问题'}

## 建议

1. 对于失败的测试，需要进一步调查根因
2. 建议增加更多边界条件测试
3. 考虑添加性能测试
4. 定期进行回归测试
