[Object] Provided is a test system operable with a simplified structure. [Solution] A test system (10) includes a test device (20) and a test device (30) each of which transports and tests a sample. The test device (20) includes a master control unit (25) which performs assignment of samples to the test device (20) and the test device (30), and control of a transport operation of the sample assigned to the test device (20). The test device (30) includes a slave control unit (35) which controls a transport operation of the sample assigned to the test device (30) by the master control unit (25).
