ChatGPT Code Review:

代码审查

1. 在 ParceWatcher Test 中，函数 generateWatcher 的返回值没有类型声明

• 建议添加类型声明增强代码的可读性和可维护性

2. 在 ParceWatcher Test 和 Watch file rename/move/new 中，变量 seed 之前已经声明并初始化为 1，但仍然在函数中通过 seed++ 的方式更改了变量值

• 建议使用新的变量名称，避免混淆和错误，如 newSeed

3. 在 Watch file rename/move/new 中，异步操作没有使用 await 关键字

• 建议补充所有异步操作的 await 关键字以确保异步操作正常执行

代码修改

Refactor: refactor file-watcher test case

• 修改函数 generateWatcher 的代码，添加类型声明
• 修改文件或文件夹的创建方式，添加了 {recursive: true} 参数
• 修改变量 seed 的名称，避免混淆和错误，并在必要时通过进行加 1 操作
• 在 Watch file rename/move/new 中添加 await 关键字来确保异步操作正常执行

提交

feat: refactor FileWatcher test cases and add type definitions for functions

• 对 FileWatcher 的测试用例进行了修改
• 为函数 generateWatcher 和其他相关函数添加了类型定义
• 为异步操作添加了 await 关键字以确保正常执行
