[英]Error: “jQuery requires a window with a document” with mocha and typescript?
我有一些正在运行的打字稿摩卡单元测试; 我已经成功导入了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"
});
我读到一个类似的问题 ,node.js中的解决方案在哪里:
var $ = require('jquery')(require("jsdom").jsdom().parentWindow);
但我试图用typings
安装jsdom
,我得到一个不同的错误表明我没有使用正确的源...
$ typings search jsdom

此外,似乎作者已放弃了node.js,转而使用io.js
我是否应该使用除jsdom以外的其他东西?
这个问题与另一个问题有关 。
无法在我的问题中声明我正在使用以下版本:
npm 3.5.2
jQuery ^ 3.2.1
jdom ^ 3.1.2
@ types / jsdom ^ 2.0.30
是否进行了以下操作(请告诉我它是否不美观)
// ...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);
});
});
