Testing touch events using your mouse

If you aren't running xCode then you can test touch events using this bookmarklet

Also Chrome has added some useful touch/device features.
1) Open your developer tools F12
2) Click the bottom right cog to open the settings panel
3) Click 'Emulate touch events' to make Chrome fire Touch Events (note it doesn't emulate page scroll)
4) Click 'Override User Agent' to choose a mobile device and emulate its user agent settings and screen width/height
