Plumbing Pressure Test Question

[SpecialK]

Hoping someone can point me in the right direction. I am building my own house and am almost done all the plumbing. The only thing I cannot find (even from our plumbing supplier) is what is used as a final cap/valve with pressure guage to inflate the system to 5 psi for the pressure test. Am I wrong in assuming that there must be something out there that caps off a rough in pipe and also has the valve to hook up a compressor and probably a dial to show the pressure is maintaining? If there is I must not be using the properly terminology to find it. Help please! Thanks in advance.

This says not to do it, though I think they used very high pressures in their demo:

I agree (about the 'not to do it'), however our local Building Inspector demands it so I am kind of stuck doing it.

Air test gauge screws to 3/4 inch NPT. So I guess you could adapt somehow. I have never done it.
