mockaf

Mocks *AnimationFrame methods.


Motivation

When unit testing, it can sometimes be useful to mock the AnimationFrame methods if the code under test makes use of them. Using mockaf allows us to execute AnimationFrame callbacks in the same tick of the event loop, making the tests a little easier to write.

Installation

``
$ npm install mockaf
`

Example

`js
var mockaf = require('mockaf');

// Mock all window *AnimationFrame methods.
mockaf.install();

// Schedule stuff.
window.requestAnimationFrame(function(){
// ...
});

// Schedule more stuff.
var id = window.requestAnimationFrame(function(){
// ...
});

// Cancel the last callback.
window.cancelAnimationFrame(id);

// Execute any callbacks stored since the last tick.
mockaf.tick();

// Restore original window.*AnimationFrame methods.
mockaf.uninstall();
`

`js
var mockaf = require('mockaf');
