UI design's exporting should support UI testing

I want to specify the detail infos of UI element,such as:value type,max,min,format(by regexpr),length…,so this info can be sent to testing team as acceptance testing input.And the second,these infos should be shown close to UI specific element when senting to testing team,and hide when is used to check with customer.so a global switcher:“show/hide element specifiction” is needed.This fuction will make UI design more engineering friendly.
