How do I programmatically create a TouchEvent in Chrome 41?

Question

I am trying to create a touch event for a unit test. After reading https://developer.mozilla.org/en-US/docs/Web/API/TouchEvent, I expected that I would be able to do:

I'm guessing the only way to do it without throwing an exception is to be more explicit in the type of event you wish to create:

var evt = document.createEvent('UIEvent');

evt.initUIEvent('touchstart', true, true);

The TouchEvent is a subclass of UIEvent.

Update

As mentioned above, while on an actual device (or emulating a device), one can easily create a TouchEvent using the standard document.createEvent method.

So perhaps a try/catch would be in order:

try {

  document.createEvent('TouchEvent');

} catch (e) {

  console.log('No touching!');

}
