酶修饰的组件TypeError：无法读取未定义的属性'contextTypes'

Question

I am testing a component decorated with JSCC with enzyme and jest, but I receive the following error:

TypeError: Cannot read property 'contextTypes' of undefined

How to test this styled component?

 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()) }) }) 

The component is decorated as:

 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 } })
