Description

verify integrated functionality of command dispatch through the SessionCommand facade.

operate lifecycle of the supporting components, similar to activating the »session subsystem«
generate command messages similar to what is received from the UI-Bus
us the handler mechanism from stage::ctrl::CoreService to talk to the facade
have a specially rigged command function to observe invocation
wait for the session loop thread to dispatch this command
verify that commands are really executed single-threaded

◆ startDispatcher()

void startDispatcher ( )

inline

Test:: start the session loop thread, similar to what the »session subsystem« does

Note: we are not actually starting the subsystem itself, but we indeed start the »session loop thread«

Test:

invoke a command in the same way as CoreService does when handling command messages from the UI-Bus

build a command message, similar to what the generic UI element does
use the contents of this message at the SessionCommand facade, similar to what CoreService does

Test:

massively multithreaded torture test to verify that commands are properly enqueued and executed one by one

create several threads to send random command messages
verify that, after executing all commands, the internal state variable reflects the result of a proper sequential calculation and summation
