This code bellow is common to all the tests in the suite. Can we factor it out to a setup function? e.g: https://github.com/aframevr/aframe/blob/master/tests/core/scene/a-scene.test.js#L214
var sceneEl = this.el;
AScene.prototype.resize.restore();
sceneEl.camera = { updateProjectionMatrix: function () {} };
sceneEl.canvas = document.createElement('canvas');
sceneEl.renderer = { setSize: function () {} };

Renderer size should only be updated on desktop in fullscreen mode.
Resizing the browser window while presenting leads to the canvas being resized accordingly, which updates resolution in the headset, causing a bad experience. Since Aframe does not rely on Three.js built-in mechanism for resizing the canvas this needs to be handled explicitly in a-scene.js.
