/** @file test-dummy-mobject.hpp
|
||
|
|
** A hierarchy of simple dummy-Media-Objects for easy unit testing.
|
||
|
|
** Normally, the creation of MObjects and corresponding Placements is defined to be
|
||
|
|
** very restricted. Any MObjects are supposed to be created by the MObjectFactory,
|
||
|
|
** which provided very specialised factory functions. When writing unit tests to
|
||
|
|
** check the basic MObject properties and behaviour, this can be an obstacle.
|
||
|
|
** Thus we create a separate branch in the MObject hierarchy with relaxed
|
||
|
|
** requirements and some dummy/test API functions.
|
||
|
|

|
|
** @see mobject::session::BuilderTool_test

** @see mobject::session::PlacementHierarchy_test
