Issue:
【TabBar】测试覆盖率提升
> 目前正在推进 mobile-vue 的组件测试覆盖率提升。

## 任务要求
- **行覆盖率达 80%+**
- **分支覆盖率 80%+**
- **语句覆盖率 80%+**
- 有交互的组件，需要覆盖所有场景，**要求函数覆盖率 80+%**

## 单元测试指引
 [mobile-vue 的单元测试指引文档](https://github.com/Tencent/tdesign-mobile-vue/wiki/mobile-vue%EF%BC%9A%E5%8D%95%E5%85%83%E6%B5%8B%E8%AF%95%E6%8C%87%E5%BC%95)

> **目前每个组件都拥有自己的测试用例文件，我们可以先通过`npm run test:unit-coverage`生成测试覆盖率报告，查看该组件的单元测试覆盖率情况，然后针对性的补充测试用例**

#### Tips
- Vitest 单元测试框架：[文档](https://cn.vitest.dev/guide/)
- 若开发工具为 vscode ，可以安装 Vitest 插件

## 激励

参与共建的开发者，将可以获得 [TDesign 周边](https://github.com/Tencent/tdesign/wiki/TDesign-%E5%91%A8%E8%BE%B9)（贴纸、鼠标垫、工卡套等）；

成为核心贡献者，将会拥有 TDesign 专属头像。
