This resolves a long-standing issue: we could not use proper include paths for test-helper code that was defined alongside the tests. Since some test-helper code must now be relocated into the »Vault«-Layer, I took the opportunity to finally resolve this annoyance. The solution is two-fold * introduce a dedicated test-support library * remove the quirks that were necessary to support some plain-C tests Together, this allows to raise the include-directory by one level, and then to adjust all folder names so that they match the namespace

|

* 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.
