You can remove it and have a mechanic test if its bad, many auto parts stores will test it for free or for a small fee. If the alternator is completely busted the car will start and quickly sputter and quit very quickly because the battery can't run the car very long before it's completely drained. If you get a jump start the car runs great and once the cables are removed the car quits after a few minutes or less. Best way to be sure, have a mechanic look at it.
- I've found in most situations once the car is started either by jump starting or a new battery is to disconnect one of the battery leads while the engine is running. If the engine stalls/dies immediately on disconnection then it's a sure bet the alternator isn't putting out any power.
Another way is to use a multimeter across the battery terminals when the engine is running and measure the voltage, if the voltage is dropping below 11 volts then it's also a sure sign the alternator isn't working.
I'd says both these options are a lot easier to test then removing the alternator from the car.

Typically you know your alternator is out when you have to jump start your car numerous times. A way you can test it is by turning on your car and while it's running discount the + terminal.
