测试反应材料-UI 图标菜单.模拟.单击不工作

Question

我正在使用"react-addons-test-utils"使用material-ui为反应组件编写一个测试用例。由于某种原因，我无法获得模拟.click来为IconMenu工作，并且不确定我做错了什么。我正在尝试模拟单击图标按钮，以便我可以循环访问弹出窗口并获取菜单项并检查长度，但由于某种原因，我不确定我做错了什么。我还注意到，当单击IconButton时，在"提供程序"标签之后的DOM中附加了一个"PopoverDefaultAnimation"。谢谢！

这是我的组件，渲染良好

import React, {PropTypes} from 'react'
/** material-ui **/
import IconMenu from 'material-ui/IconMenu'
import IconButton from 'material-ui/IconButton'
import MenuItem from 'material-ui/MenuItem'
import Divider from 'material-ui/Divider'
import Help from 'material-ui/svg-icons/action/help-outline'
import getMuiTheme from 'material-ui/styles/getMuiTheme'

    export default class MndyHelp extends React.Component{
    constructor(props) {
        //console.log('Main: constructor()');
        super(props);
    }
     static childContextTypes = {
        muiTheme: React.PropTypes.object
    }
    getChildContext() {
        return {
            muiTheme: getMuiTheme()
        }
    }
    render(){
    var urlLink = "https://www.google.com";
        return(
            <IconMenu
                iconButtonElement={
                      <IconButton style={ {padding: 0, width: "auto", height: "auto", right: 44, top: 4 } } iconStyle={{ height: 30, width: 30, fill: "#304954"}}><Help/></IconButton>}>
                <MenuItem onTouchTap={() => {window.open(urlLink, '_blank');}} primaryText='Item1'/>
                <MenuItem onTouchTap={() => {window.open(urlLink, '_blank');}} primaryText='Item2'/>
            </IconMenu>
        );
    }
}

这是我的单元测试：

import React from 'react'
import {renderIntoDocument,
    scryRenderedDOMComponentsWithTag,
    scryRenderedComponentsWithType,
    Simulate
} from 'react-addons-test-utils'
import chai from 'chai'
import ReactDOM from 'react-dom'
import IconButton from 'material-ui/IconButton'
import IconMenu from 'material-ui/IconMenu'
import MenuItem from 'material-ui/MenuItem'
import Popover from 'material-ui/Popover';
import Help from 'material-ui/svg-icons/action/help-outline'
var should = chai.should(),
    expect = chai.expect;
import MndyHelp from './MndyHelp.jsx';
describe('<MndyHelp/>', () => {
    //render kndyhelp
    //get the iconbutton
    //get the popover
    //click the icon button
    it('should have 2 menuItems', () => {
        var domElement  = renderIntoDocument(<MndyHelp/>),
            buttons     = scryRenderedComponentsWithType(domElement,IconButton),
            firstButton = ReactDOM.findDOMNode(buttons[0]);
            Simulate.click(firstButton);
            var popOver = scryRenderedComponentsWithType(domElement,Popover);
            var menuItem = scryRenderedComponentsWithType(domElement,MenuItem);
            //make sure popover is open i.e. true
            expect(popOver[0].props.open).to.equal(true);
            //Make sure menu items exist
            expect(menuItem.length).to.not.equal(0);
            expect(menuItem.length).to.equal(2);
    });
});

您无法模拟单击，因为没有可单击的内容。

您有一个onTouchTap事件，很遗憾您无法使用Simulate。

事实上，你正在使用的插件会阻止点击发生：

当点击发生时，浏览器会发送触摸开始和触摸结束，然后在 300 毫秒后发送点击事件。如果单击事件之前有触摸事件（在最后一次触摸事件的 750 毫秒内），则此插件将忽略该事件。
