PURPOSE:To point out plural comparative error generating instructions, which can occur in a random test sequence at the time of comparative error generation, by repeatedly executing the random test sequence at the time of comparative error generation within the upper limit of the number of times for generating comparative error while successively changing the number of instructions. CONSTITUTION:A main storage device stores a random test task 20, random test program generated by the random test task 20 and operating system 10, and an information processor 1 to be tested is connected to the main storage device. The random test task 20 is provided with a comparative error generation time upper limit setting means 21, random test program generating means 22, expected value generating means 23, test instruction executing means 24, executed result judging means 25, test re-executing means 26, and comparative error detecting instruction point-out means 27. |
