STEPS:

1) create QSystemScreenSaver object
QSystemScreenSaver s;

2) check if screen saver is inhibited or not:
bool isInhibited = s.screenSaverInhibited();

Expected result:
false is returned, since right after constructing the object the screen should not be inhibited.

Actual result:
If the device screen is currently on, then true will be returned.
If the device screen is currently off, then false will be returned.
