Dodge SX2.0, bad alternator or bad battery?

I have a 2003 Dodge SX2.0, Have not turned it on in a while and when I did go to turn the ignition not even the dash lights would turn on, absolutely nothing.

I proceeded to boost the battery. Car ran fine, kept it running for a while. As I go to remove the booster cables the entire car will shut down. I then proceeded to place the cables once again and give the car some gas. Had someone else remove the cables while I kept my foot on the gas. The car will keep running with my foot on the gas (dashboard lights dimming on and off the whole time) as soon as I stop revving the car will shut down completely once again.

Sound like the alternator or the battery? How can I test this myself?
