ZombieBox extension for Pixel Perfect testing.

Usage

Instantiate the controller class (Controller) and attach it to the application:

``js
import PixelPerfectController from 'pixelperfect/controller';
import BaseApplication from 'generated/zb/base-application';

/**
*/
export default class Application extends BaseApplication {
/**
*/
onReady() {
this._pixelPerfectController = new PixelPerfectController();
this._pixelPerfectController.attachToApp(this);
}
}
`

Let the controller to intercept processing of the remote:

`js
import PixelPerfectController from 'pixelperfect/controller';
import BaseApplication from 'generated/zb/base-application';

/**
*/
export default class Application extends BaseApplication {
/**
* @override
*/
processKey(zbKey, opt_e) {
if (this._pixelPerfectController.processKey(zbKey, opt_e)) {
return true;
}

return super.processKey(zbKey, opt_e);
}
}
`

Implement interface IMarkupProvider by the scene which is supposed to be tested.

`js
import AbstractCuteScene from 'cutejs/layers/abstract-scene';
import IMarkupProvider from 'pixelperfect/i-markup-provider';

/*
* @implements {IMarkupProvider}
*/
class Home extends AbstractCuteScene {
/**
* @override
*/
getMarkupImage() {
return [
'http://zombiebox.tv/home-markup-reference.png',
'web/markup-references/home.png'
];
}
}
`
