type the command 'dmesg' after the test or inspect the file /var/log/messages 
(as root)

There is a mix of old and new tests. The old ones do not necesarily produce 
output, but PASS means that :

a) the module could be loaded
b) things did not crash

Actually, any standard test should only notify that it has been loaded and 
unloaded with or without error so that the user is not overloaded by unneeded 
messages.

you need to do this ALWAYS in init_module if you want to use C++ programs. It 
makes that you can use global variables or static class members. The function 
calls their constructors.

look in the files InitFramework.cpp, moduleStartStop.c RunFramework.cpp

it initialises/destroys the threads that will be used in the realtime system. 
RunFramework.cpp will start and stop them.

rtos_printf( "\nCore loaded\n\n" ); <-- this text doesn't

do a 'dmesg' command and you should see the output. dmesg is a key tool for 
inspecting messages from the realtime system
