how to test a fuel pressure regulator for 1:1 boost

I want to test my fuel pressure regulator for 1:1 boost. so, can I just add pressure on the regulator and see if the fuel pressure follows. I plan on doing this at engine idle...or I guess it doesn't really need to running. Is my thinking correct?

correct. pump on and use a vacuum pump/pressure tester on the vac line to the reg. if base is 42 psi, you add 10 inchs of pressure the fuel pressure should go to 52
