PROBLEM TO BE SOLVED: To provide a test device suitable for automatically performing durability test. SOLUTION: A sensor is attached to a work (engine) (S1) to start the durability test (S2). After a fixed period has elapsed, the endurance test is once stopped (S3). The sensing data obtained are transferred to a determination algorithm forming means in a testing device 10 (S4). If it is an initial state, it is inferred as being a normal state. The determination algorithm forming means forms a standard space and a determination model which are numeralized as the normal wave form data and are specified the normal region and are registered to the determination algorithm (S5). A threshold for determining abnormality from the determination model is set (S6). Then, the durability test is resumed (S7). The engine is made to rotate over a long period. The sensing data, obtained during the endurance test on each sensor are given to the determination algorithm inside the testing device, a state determination is performed in real time (S8); and if the threshold is exceeded, a stoppage instruction will be output to the durability testing machine instantaneously (S9).
