  ✕ renders without crashing (36ms)

The test source code:

import * as React from 'react'
import * as ReactDOM from 'react-dom'
import App from './App'

it('render', () => {
  const div = document.createElement('div')
  ReactDOM.render(<App />, div)
})

Import redux store will solve this problem

import * as React from 'react'
import * as ReactDOM from 'react-dom'
import { Provider } from 'react-redux'

import App from './App'
import configureStore from './configureStore'

const store = configureStore({})
it('render', () => {
  const div = document.createElement('div')
  ReactDOM.render(
    <Provider store={store}>
      <App />
    </Provider>,
    div,
  )
})
