Andrew Clark 9b36df86c6 Use requestIdleCallback timeout to force expiration (#11548 )

* Don't call idle callback unless there's time remaining

* Expiration fixture

Fixture that demonstrates how async work expires after a certain interval.
The fixture clogs the main thread with animation work, so it only works if the
`timeout` option is provided to `requestIdleCallback`.

* Pass timeout option to requestIdleCallback

Forces `requestIdleCallback` to fire if too much time has elapsed, even if the
main thread is busy. Required to make expiration times work properly. Otherwise,
async work can expire, but React never has a chance to flush it because the
browser never calls into React.

`react-test-renderer`

This package provides an experimental React renderer that can be used to render React components to pure JavaScript objects, without depending on the DOM or a native mobile environment.

Essentially, this package makes it easy to grab a snapshot of the "DOM tree" rendered by a React DOM or React Native component without using a browser or jsdom.

Usage:

const ReactTestRenderer = require('react-test-renderer');

const renderer = ReactTestRenderer.create(
  <Link page="https://www.facebook.com/">Facebook</Link>
);

console.log(renderer.toJSON());
// { type: 'a',
//   props: { href: 'https://www.facebook.com/' },
//   children: [ 'Facebook' ] }

You can also use Jest's snapshot testing feature to automatically save a copy of the JSON tree to a file and check in your tests that it hasn't changed: http://facebook.github.io/jest/blog/2016/07/27/jest-14.html.
