Can you test an O2 sensor?

Basically, I need to know if my O2 is bad. Can a local shop test them? By shop I mean AutoZone or O-Reillys..

Re: Can you test an O2 sensor?

If you have access to a scanner, the mV's will change pretty rapidly around 100mV upwards to 900mV's. I beleive they also take 5V, so you could see if you get 5 volts at the connector that plugs into the o2.
