在运行摩卡测试时使用不同的babel预设 [英] use different babel preset when running mocha tests

问题描述

我的npm软件包构建使用babel运行，并且我在package.json中使用

My npm package build runs with babel and I configured a babel preset in my package.json with

"babel": { "presets": ["es2015"] }

我还配置了一个摩卡测试脚本

I also configured a mocha test script with

"test": "mocha --compilers js:babel-core/register"

但是，我想使用不同于为构建指定的babel预设运行测试.

However, I would like to run my tests using a different babel preset than that one specified for my build.

有可能吗?我会实现吗?

Is it possible? I would you achieve that?

推荐答案

您可以创建一个名为babel-hook.js的文件并将其放入:

You could create a file named babel-hook.js and put in it:

require("babel-register")({
  presets: [ /* whatever values you want here */ ],
});

然后像这样运行Mocha:

then run Mocha like this:

mocha --require babel-hook

这将注册Babel，您可以使用任何配置选项您想要的它，与package.json中的任何内容分开.

This will register Babel and you can use any configuration option you want with it, separate from anything in package.json.
