Question

在：

const jsdom = require("jsdom");
const initialVirtualConsole = jsdom.createVirtualConsole();

我明白了：

TypeError: jsdom.createVirtualConsole is not a function
    at Query.<anonymous> (/my_jsdom_script.js:112:55)
    at emitNone (events.js:72:20)
    at Query.emit (events.js:166:7)

我想在本地机器上运行jsdom的测试，看看jsdom在我的本地环境中的表现。

在https://github.com/tmpvar/jsdom/tree/master/test中运行测试时，有没有人可以指导一个菜鸟？

这是beforeEach()块中的内容（我使用mocha over node.js进行测试）

    import jsdom from 'jsdom'
    const virtualConsole = jsdom.createVirtualConsole()
    const document = jsdom.jsdom(undefined, {
        virtualConsole: virtualConsole.sendTo(console)
    })
    virtualConsole.on('log', (...args) => {
        // do something with `args` sent to logs
        // e.g, assign result to a variable and run your assertions over it
    })
    window = document.defaultView
    global.window = window
    global.document = document
