PURPOSE: A hydraulic test apparatus is provided to improve usage efficiency of the hydraulic test apparatus by previously performing operation test of a large hydraulic test apparatus. CONSTITUTION: A hydraulic test apparatus includes an oil storage tank(100), a pump(110), a pressure adjusting part, a solenoid valve(130), an oil supplying part, and an oil retrieving path. The oil storage tank(100) stores oil. The pump performs pumping with respect to oil stored in the oil storage tank. The pressure adjusting part controls the pressure of oil pumped from the pump by dividing a pressure state into plural different pressure states. The solenoid valves controls the supply of oil through the pressure adjusting part. The oil supplying part(130) supplies oil to a targeted device in different pressure states according to the operation of the solenoid valve.
