description	The invention provides an oil-well pump testing method, an oil-well pump testing device and an oil-well pump testing machine which are different from the prior art. A connector is changed into the outer circumference for sealing an oil-well pump; the efficiency is improved, the problems caused by the original connection pressure test joint test are avoided, and the link of fixing the tested oil well pump is added after sealing in order to overcome the defect that the sealing outer circumference cannot achieve the fixing effect; according to the oil well pump testing device, a large-gap sealing ring is adopted to seal the outer circumference of an oil well pump, a limiting ring comprising two semi-rings is designed to fix the oil well pump, it is guaranteed that the oil well pump is fixed in a test and convenient to enter and exit, a limiting seat is designed to assist limiting, the limiting ring is tightly attached to the limiting seat, axial force is borne by the limiting seat, and possible deformation and d
