GNOME Desktop Testing new framework

Eitan Isaacson and Ara Pulido had discussion about a new design for gnome desktop testing and the initial version of code is available here and the spec of the same is available here. Soon it will be merged back to main line.

We welcome all your suggestions.

Ara will be publishing templates of writing new test scripts and also planing to create a new VM with latest gnome and all required settings for automation.
