javascript - enzyme 修饰组件 TypeError : Cannot read property 'contextTypes' of undefined

Question

我正在使用 enzyme 和 Jest 测试用 JSCC 装饰的组件，但收到以下错误:

TypeError: Cannot read property 'contextTypes' of undefined

如何测试这个样式组件？

import React from 'react'
import { shallow } from 'enzyme'
import { PdfViewer } from './PdfViewer'

const baseProps = {
  location: 'url',
  defaultPage: 1,
  classes: {},
  handlePageChanged: () => {},
}

describe('<PdfViewer />', () => {
  it('should work', () => {
    const wrapper = shallow(<PdfViewer {...baseProps} />)
    console.log(wrapper.debug())
  })
})

该组件被装饰为:

class PdfViewer extends React.Component{}
../
export default withStyles(styleSheet)(PdfViewer)

Answer 1

import { muiTheme } from 'material-ui/styles'  
const wrapper = shallow(<PdfViewer {...baseProps} />, { context: { muiTheme } })
