Patent ID: 7165001

Claim:
An operation testing method, comprising: a processing operation execution step of causing a processing apparatus to be tested to carry out a predetermined processing operation in a predetermined processing condition; a processing load factor measurement step of measuring a processing load factor in the processing apparatus for when the predetermined processing operation is carried out in the processing apparatus; a processing load factor comparison step of comparing the measured processing load factor with a predetermined target processing load factor range; a processing condition adjustment step of adjusting the predetermined processing condition such that the measured processing load factor falls within the predetermined target processing load factor range; and an operation verification step of carrying out operation verification of the apparatus in a condition where the measured processing load factor falls within the target processing load factor range, and wherein: the processing operation execution step, the processing load factor measurement step, the processing load factor comparison step, the processing condition adjustment step, and the operation verification step are repeated while the target processing load factor range is changed in a predetermined manner.
