the buildsystem will now pick up and link all test cases according to the layer, e.g. backend tests will automatically be linked against the backend + library solely.

* @test basic usage of the Proc-Layer command dispatch system.
|
|
* Shows how to define a simple command inline and how to
|
|
* trigger execution and UNDO. Verifies the command action
|
|
* takes place and is reverted again by the UNDO function.
|
|
*
|
|
* This is a simplified demonstration. Usually, commands would be defined
|
|
* in bulk and without specifying parameters. Later, typically client code
|
|
* accesses a handle by ID, binds to the concrete argument and dispatches
|
|
* the invocation. Note in this example that by using a smart-ptr as
|
|
* argument allows accessing an object by reference and late binding.
