The contracts between the components and the container are violated by the modules, but this is not detected by the specs
// containers/form_container.js
import Form from '../components/form_component';
// The container passes a 'username' prop (type: string) to Form
export const mapStateToProps = state => ({ username: state.username });
export connect(mapStateToProps)(Form);
