ABSTRACT:
There is provided a test apparatus that tests a device under test. The test apparatus includes a control processor that executes a test program for testing the device under test, a test unit that is connected to the device under test and tests the device under test according to an instruction from the control processor, and a relay section that is connected to the control processor and the test unit and relays a control instruction sent from the control processor to the test unit. The relay section includes a polling section that repeatedly reads a status register showing a state of the test unit, which is designated by the control processor, and a process control section that sends the control instruction to be processed by the test unit after a value of the status register becomes an expected value to the test unit according to the fact that the value of the status register becomes the expected value designated by the control processor.
