1. A method of conducting a pressure test on a piping and manifold system configured to provide fluid flow from a plurality of pumping units into a well via a wellhead, comprising:
connecting the plurality of pumping units to a discharge manifold, wherein a fluid outlet on each of the plurality of pumping units is in fluid communication with the discharge manifold via a respective discharge flowline;
connecting the wellhead of the well to the discharge manifold via a wellhead flowline;
isolating the wellhead from the fluid flow into the well to form a closed test system;
operating at least one and less than all of the plurality of pumping units to pump fluid into and pressurize the closed test system to a first predetermined pressure;
upon reaching the first predetermined pressure, halting pumping of fluid by the at least one of the plurality of pumping units;
continuing pumping of fluid into the closed test system with at least one pressure test pump to pressurize the manifold and piping to a final predetermined pressure; and
upon reaching the final predetermined pressure, halting pumping of the fluid by the at least one pressure test pump,
wherein the at least one pressure test pump has a horsepower equal to or less than 1% of a horsepower of each of the plurality of pumping units.
