Testing with Jest: Tip #7

App-test.jsx

import renderer from 'react-test-renderer'
import App from '../App'

// Generated snapshot is exactly like the previous example
// while it's possible to override the default mock
// by using the same jest.mock command as before
// if this test need a different behavior than the
// glboal mock.

it('should render correctly', () => {
  const component = renderer.create(<App />)
  expect(component.toJSON()).toMatchSnapshot()
})

react-router-dom.jsx

export const Router = ({ children, ...props }) =>
  typeof children === 'function'
    ? children({ match: path === '/somewhere' })
    : createElement('Route', props)

export const Link = 'Link'
