Disclosed is a system and method for testing electronic devices which uses a random pattern for testing electronic devices. In one embodiment there is communicated to a device under test (DUT) a test sequence causing the DUT to exercise certain parameters in a controlled pattern of operation. The test sequence is randomly created. In one embodiment this random creation is controlled by a random looping algorithm which controls both the order of and the magnitude of each parameter. Included, if desired, is the ability to selectively retransmit previously communicated test sequences.
