javascript - 警告 : Failed prop type: The prop open is marked as required in Snackbar, 但其值未定义

Question

我正在尝试为我的应用引入 jest 快照测试。

LoginForm 组件

render() {
    return (
    ...
    <DynamicSnack
        dialogOpen={this.props.dialogOpen}
        snackOpen={this.props.snackOpen}
        snackTimer={this.props.snackTimer}
        snackMessage={this.props.snackMessage}
    />
    )
}

DynamicSnack 组件

import Snackbar from 'material-ui/Snackbar';

render() {
    let { snackOpen, snackTimer, snackMessage } = this.props

    return (
        <Snackbar
            open={snackOpen}
            message={snackMessage}
            autoHideDuration={snackTimer}
            onRequestClose={this.closeSnack}
        />
    )
}

LoginForm.spec.js

import React from 'react'
import renderer from 'react-test-renderer'
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';

import LoginForm from '../../app/components/loginComponents/loginForm'

describe('LoginForm', () => {
    it('should render snapshot', () => {
        const component = renderer.create(
            <MuiThemeProvider>
                <LoginForm />
            </MuiThemeProvider>
        )
        const tree = component.toJSON()
        expect(tree).toMatchSnapshot()
    })
})

警告:

Warning: Failed prop type: The prop message is marked as required in Snackbar, but its value is undefined.
Warning: Failed prop type: The prop open is marked as required in Snackbar, but its value is undefined.

我尝试直接导入 DynamicSnack 组件甚至 Snackbar 并手动添加属性 open={false} message={'w00f'} 但没有任何变化。

我是单元测试的新手，正在尝试从学习 jest 开始。

我怎样才能摆脱这些警告？

解决方案非常简单，在测试 LoginForm 时，您没有传递 Snackbar 需要的 Prop 。将它们作为

 const component = renderer.create(
        <MuiThemeProvider>
            <LoginForm snackOpen={true}
    snackMessage={'Wrong info'}/>
        </MuiThemeProvider>
    )
