SX Chips Tested?

I noticed on the Parallax website that all the 250 SX48 chips in a tray are tested before shipping.
How are they tested? Is there a special test jig that can connect to all the pins without soldering?

The memory, RAM, I/O pins, internal oscillator are all tested at different operating voltages.
A Propeller chip is programmed for this task.
