Claim 15:
16. A method of operating a pressure testing assembly to perform a pneumatic pressure test on a test subject, the pressure testing assembly comprising:
a manifold comprising:
a pneumatic pressure testing path comprising a plurality of piping components configured to join, in gaseous fluid communication,
a regulator having a high-pressure gauge, a low-pressure gauge, and a source gas inlet,
a ball valve,
system test gauge,
a vent valve,
a system test port, and
a system relief valve;

a hydrostatic pressure testing path comprising a subset of the plurality of piping components configured to join, in liquid fluid communication,
a spare port,
the system test gauge,
the vent valve,
the system test port,
the system relief valve, and
the ball valve; and

a case configured to mechanically carry the manifold;

the method comprising the steps of:
receiving, using a cartridge valve coupling, the system relief valve;
closing the ball valve;
connecting in gaseous fluid communication the system test port to the test subject;
receiving, using the source gas inlet of the regulator, an input gas;
iteratively increasing, by a step pressure, a cumulative pressure of the input gas at the system test gauge until
upon leak detection at the cumulative pressure using the system test gauge, reducing the cumulative pressure by a percentage of the cumulative pressure, and
upon the cumulative pressure equaling a test pressure, holding the test pressure for a time step.
