            ).exists(<h1>Test page</h1>)
import { connect } from 'react-redux'

// Use named export for unconnected component (for tests)
export class App extends Component { /* ... */ }
// Use default export for the connected component (for app)
export default connect(mapStateToProps)(App)

import { App } from './App'
import ConnectedApp, { App } from './App'
import App from './App'
