Actually to see if the alternator has failed in this manner [say you are driving a long distance], you would need to stop the car periodically, shut it off, then turn the key switch on to see if the Batt light does not come on when first starting the engine!
One way to solve this lack of notification of a problem is to install a voltmeter. They also make voltmeters which plug into a cigarette lighter.
