Error: "jQuery requires a window with a document" with mocha and typescript?

Question

我有一些 typescript mocha 单元测试运行；我已成功导入 jquery，但出现错误：

import * as $ from 'jquery';  // or maybe this should be in beforeEach() ?

...
it('should append a div', function() {
   $("body").append("div");  // ERROR: Causes "jQuery requires a window with a document"

});

我读了一篇 similar question，其中 node.js 中的解决方案是：

var $ = require('jquery')(require("jsdom").jsdom().parentWindow);

但我尝试使用 typings 安装 jsdom，但我收到了一个不同的错误，表明我没有使用正确的源...

$ typings search jsdom

而且作者似乎已经放弃了node.js in favor of io.js

我应该使用 jsdom 以外的其他东西吗？

Answer 1

此问题与有关。

未能在我的问题中说明我使用的是以下版本：

node.js v4.2.6
打字 2.1.1
npm 3.5.2
jquery^3.2.1
jdom ^3.1.2
@types/jsdom^2.0.30

是否做了以下事情（有不雅之处请告知）

// ...chai and mocha imports...
import * as jsdom from 'jsdom';
import * as jq from 'jquery';

// Import code to test...
import MeCode from './pirates/MeCode';
// ..

// testing inits
chai.use(chaiAsPromised);
const expect = chai.expect;
const assert = chai.assert;
const should = chai.should();

let mc,$ = null;
let someId = "yarId";

describe('Main Hooks', () => {
    // ..
    beforeEach(function() {
       // Initialize jQuery with a DOM it can work on....
       $ = jq(jsdom.jsdom().parentWindow);

       // Initialize the object I'm testing...
       mc = new MeCode($, someId);
    });

    afterEach(function() {
       // clean up
       // ...
    });
    // ..

    it('should generate html', function() {
       ($("#" + someId).length).should.be.equal(1);
    });
});
