Question

我正在尝试执行一个酶/ mocha / chai测试来模拟在一个materialUI Checkbox标签中将checked的状态从true更改为false，该标签由redux-form字段包装并呈现。我能够模拟嵌套在Field标签内的本机组件（复选框等）的点击，但是在嵌套时无法模拟材质UI标签上的点击。我可以访问Checkbox标签上的其他属性，但无法模拟事件。

UserForm.jsx   

renderCheckbox(props) {
  return (
   <Checkbox
      label={props.label}
      value={props.input.value}

// working code in the app:
      onChange={ event => {
      this.props.actions.toggleSuperAdmin(props.input.value)}}

// test code, not able to simulate even this click in Enzyme, 
// tried to break function down into simplest event I could think of, 
// and still not functioning in the test:               
      onCheck={() => console.log("onClick in UserForm.jsx")}

      {...props.input}
   />
  )
}

在我的渲染函数内部，有一段调用renderCheckbox

的代码块

    UserForm.jsx  

    render() {
        return (
          <Paper zDepth={0} rounded={false}>
            <form id='user-form' onSubmit=
    {this.props.handleSubmit(this.handleUserSubmit.bind(this))}>
              <Field name='is_super_admin' 
                component={this.renderCheckbox} 
                label='Work Institute Employee / Super Admin'/>
            </form>
          </Paper>

这是我的测试 - 我甚至不担心期望，我只是想尝试在UserForm.jsx中触发的click事件登出我的控制台。但是我包含了几行已注释掉的代码，所以你可以看到我试图用它去的地方最终我可以在Checkbox中嵌入的Click事件中嵌入字段来注销。我不确定问题是否与酶，还原形式或材料UI有关，但两者之间的相互作用不允许我模拟酶中的事件。

import ConnectedUserForm, { UserForm } from '../../../www/components/UserForm'
import { expect, shallow, render, React, sinon, mount } from '../../_utils'
import jwt from 'jsonwebtoken'
import getMuiTheme from 'material-ui/styles/getMuiTheme'
import { Field } from 'redux-form/immutable'
import Checkbox from 'material-ui/Checkbox';
import Paper from 'material-ui/Paper'  
import { reducer as formReducer } from 'redux-form'
import { createStore, combineReducers } from 'redux'
import { Provider } from 'react-redux'
import jsdom from 'jsdom'

global.document = jsdom.jsdom('<!doctype html><html><body></body></html>')
global.window = document.defaultView

it('toggleSuperAdmin function should fire when checkbox is checked', () => {
props.user.is_super_admin = 1

let store = createStore(combineReducers({ form: formReducer }))
const userForm = mount(
  <Provider store={store}>
     <ConnectedUserForm {...props} />
  </Provider>, options)

const checkB = userForm.find(Checkbox)

checkB.simulate('check')

// console.log("checkB1", checkB.getNodes()[0].props);

// checkB.simulate('change', {target: { isInputChecked: true }})

// console.log("checkB2", checkB.getNodes()[0].props);

//    expect(props.actions.toggleSuperAdmin.calledOnce).to.be.true
  })

谢谢！

我遇到了同样的问题并在此处找到答案：https://github.com/callemall/material-ui/blob/master/src/Checkbox/Checkbox.spec.js

  const input = wrapper.find('input');
  input.node.checked = !input.node.checked;
  input.simulate('change');

当嵌套在redux-form字段标签
