Question

我需要一些帮助。我正在尝试使用Mocha在react / readux应用程序中进行测试。不幸的是，将代码编译为es5似乎存在问题，因为我收到了这个错误：

Unexpected token (13:15)
  11 |   switch (action.type) {
  12 |     case types.ADD_USER:
> 13 |       return { ...state, list: [ ...state.list, action.payload ] };
     |                ^
  14 | 
  15 |     case types.DELETE_USER:
  16 |       let deletedState = state.list.filter(user => user.id !== action.payload);
    at Parser.pp$5.raise

我密切关注此博客条目以设置测试环境：http://jamesknelson.com/testing-in-es6-with-mocha-and-babel-6/

另外，我用这个条目创建了一个.babelrc：

"presets": ["es2015", "react"]

这是我的package.json：

  "version": "0.1.1",

    "test": "mocha --compilers js:babel-core/register",
    "test:watch": "npm test -- --watch",
    "eject": "react-scripts eject"
  }
}

我绝对不知道我做错了什么。任何意见都非常欢迎。

修改我在重复的线程中尝试了解决方案并安装了以下包：

齐的jquery 巴贝尔-插件变换对象，其余的扩频巴别预置级-2

并将我的.babelrc更改为

{
  "presets": ["es2015", "react", "stage-2"],
  "plugins": ["transform-object-rest-spread"]
}

我现在在尝试运行npm test时收到此错误消息：

global.document = _jsdom2.default.jsdom('<!doctype html><html><body></body></html>');
                                  ^

TypeError: _jsdom2.default.jsdom is not a function
    at Object.<anonymous>

尝试使用Mocha进行测试时，Babel不会将es6编译为es5
