mockaf
v1.0.5 mock animation frame request cancel
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
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();
API
