[gnome-boxes/wip/automated-tests: 6/21] Add automated snapshots tests

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit ffe150e04ddf034bbed9e7ea5d853cae1fdd4680
Author: Vladimir Benes <vbenes redhat com>
Date:   Tue Jan 6 09:42:20 2015 -0500

    Add automated snapshots tests
    
    Snapshots are tested via saving snapshot with working network then
    shutting the network down from inside the box and reverting back to the
    working state.
    
    Coverage:
     * Create and revert snapshots
     * Rename snapshot
     * Delete

+Feature: Snapshots

+  Background:
+    * Make sure that gnome-boxes is running
+    * Wait until overview is loaded
+
+  @snapshots_create_an_revert
+  Scenario: Create snapshots and revert to them

+    * Go into "Core-5" box
+    * Wait for "sleep 1" end
