A recording medium has a program recorded to operate a testing apparatus for testing an electronic device. The program causes the testing apparatus to perform functions as a comparing unit for comparing an output signal from the electronic device with an expected value, a timing generating unit for generating a rate signal and providing the comparing unit with the rate signal, wherein the rate signal determines timing at which the comparing unit compares the output signal with the expected value, a fail memory for saving the comparison results obtained by comparing the output signal with the expected value successively according to the rate signal to different addresses, and a period calculating unit for calculating a period of the output signal based on the comparison results stored successively in the fail memory, when executing a test for measuring the period of the output signal.
