How can I set props and update a rendered component?

import React from 'react'
import { mount } from 'enzyme'

// Define your component
const Headline = (props) => <h1>{props.message}</h1>

// Confirm component displays the original message
const prevProps = { message: 'hello world' }
const component = mount(<Headline {...prevProps} />)
expect(component.text()).toBe(prevProps.message)

// Confirm component displays the revised message
const nextProps = { message: 'bye-bye world' }
component.setProps(nextProps).update()
expect(component.text()).toBe(nextProps.message)
