Just checking-- are you ok with your new test being Aura-only?

[wjmaclean, 2017/01/13 21:59:22]

I think so ... the existing touch-test is Aura only, and RenderWidgetHostViewMac
doesn't (so far as I'm aware) provide support for touchscreen touch events. This
test should presumably run Linux/CrOS and Windows, just leaving Android. It
would be nice to add that later, but for now I'm going for the low-hanging
fruit.

 // Browser process hit testing is not implemented on Android, and this test
 // requires Aura for RenderWidgetHostViewAura::OnTouchEvent().

   SurfaceHitTestReadyNotifier notifier(

nit: Add blank line after.
