/** @file test/nexus.hpp
|
||
|
|
** A generic interface element instrumented for unit testing.
|
||
|
|
** All relevant building blocks within the Lumiera GTK UI are based on
|
||
|
|
** gui::model::Tangible, meaning that any generic effect of interface interactions
|
||
|
|
** can be expressed in terms of this interface contract. As far as the UI participates
|
||
|
|
** in interactions with the lower layers, like e.g. command invocation, structure updates
|
||
|
|
** and state notifications, these processes can be modelled and verified with the help
|
||
|
|
** of a specially prepared Tangible instance. This gui::test::MockElm provides the
|
||
|
|
** necessary instrumentation to observe what has been invoked and received.
|
||
|
|
**
|
||
|
|
** @todo initial draft and WIP-WIP-WIP as of 11/2015
|
||
|
|
**
|
||
|
|
** @see abstract-tangible-test.cpp
|
