Look analog.com they have something. How they call them: opamp evaluation boards I think.

See their application notes which have schematics in them.

You will need well compensated OP amps other than Device Under Test. And, small voltages such as input offset voltage will be amplified to measure them easily. Small currents such as input offset currents will be directed to flow a large known value of resistance to measure easily, i.e., current is calculated from the voltage drop across the resistor. And, you will need a timer and two analog comparators to measure some timing parameters.

This site help show a go /no go tester

The most important thing is to understand the definition of AC and DC paramter of of OP-amp than you will understand how to set up the test bench. This lengthy document will help you:

Yes it does.
OPAMP is often used as abbreviation for operational amplifier.
You could just have used google instead of asking, it would have been easier!
