Description

Implementation of a fake UI backbone for testing.

This compilation unit provides the actual setup for running a faked user interface from unit tests. Test code is assumed to access those features through the front-end, while the actual implementation instances are placed as singletons

This test setup will mostly treat messages similar to the real UI-Bus hub, with additional logging. Since the TestNexus runs as singleton, there is a single shared "nexus-log", which can be accessed or even cleared through the static front-end. But there is no connection to any core services, so neither commands nor state marks will be processed in any way. In case the unit tests need to integrate with or verify these handling operations, we provide the ability to install custom handler functions.
