On a headless ARM system that hence can't run Lazarus, I completely did 
and tested the application on a Linux PC, with everything that is not 
available on the target (in that case among other stuff everything GUI 
related including timers) in a "simulation" unit that provides Stimuli 
and Debug outputs is appropriate classes. That can nicely be done in a 
completely Object oriented way using Events (callbacks), properties and 

So the complex "business logic" could be decently tested. Only a rather 
simple dedicated "embedded" unit replacing the "simulation" unit 
(providing the same classes) was done to have it compile and run on the 
On the GUI-less target this could be tested with some simple "writeline" 
Debug outputs.
