/** @file abstract-tangible-test.cpp
 ** Verify the common base shared by all interface elements of relevance.
 ** This test is not so much a test, than a test of the test support for testing
 ** [primary elements][gui::model::Tangible] of the Lumiera GTK UI. Any such element
 ** is connected to the [UI-Bus][gui::UiBus] and responds to some generic actions and
 ** interaction patterns. This is the foundation of any presentation state recording
 ** and restoration, and it serves to invoke any persistent action on the
 ** [Session] through a single channel and access point.
 ** 
 ** What is covered here is actually a **test mock**. Which in turn enables us
 ** to cover interface interactions and behaviour in a generic fashion, without
 ** actually having to operate the interface.
 ** 
 ** @note as of 11/2015 this is a draft into the blue...

       * to this mocked interface. And since this mock element embodies an

       * of expected events, invocations and responses.
