How does one add a "test" pad in eagle PCB?

How does one add a "test pad" of arbitrary size in Eagle PCB design?

Also, does Eagle allow control of what type of via should be built into a multilayer PCB i.e a via sandwitched between layers or open and accessible on top/bottom layers?

Hi,

add a testpoint in the schematic window. Use the options to select size.
You may also adjust size in board window with "change package".

It´s the same as adding a resistor..

In detail it depends on the used library and device.

I assume that a part must exist in the library named "test point" or something along those lines. Is that correct?

If you are planing to use these test points with a bed of nails tester, you should first know what are the constraints that the manufacturer impose for placement of these testpoints. It suffice for determining its diameter and clearance from other testpoints.

In general it is placed on the bottom side of the board.
