网络测试工具

工具介绍：

这是一个功能完整的网络测速工具，可以测试网络的下载速度、上传速度和延迟。

功能特点：

1. 速度测试

   - 下载速度测试

   - 上传速度测试

   - Ping延迟测试

   - 自动选择最佳服务器

2. 实时显示

   - 进度条显示测试进度

   - 实时显示测试状态

   - 清晰的数据展示

3. 历史记录

   - 保存测试历史

   - 显示最近6次测试结果

   - 支持导出历史记录

使用要求：

- Python 3.6+

- 需要安装的库：

  python -m pip install speedtest-cli

使用方法：

1. 安装依赖：

   - 首先安装必要的库

   - 确保网络连接正常

2. 开始测速：

   - 点击"开始测速"按钮

   - 等待测试完成（约1-2分钟）

   - 查看测试结果

3. 历史记录：

   - 自动保存每次测试结果

   - 查看最近的测试历史

   - 可导出完整历史记录
