A test system for testing electrostatic testers, is used to test at least one electrostatic tester each including a voltage test terminal and a connection test terminal. The test system includes at least one optical coupler circuit and a chip. Each optical coupler circuit is coupled the voltage test terminal and the connection test terminal of one corresponding electrostatic tester, and each optical coupler circuit converts voltages of the voltage test terminal and the connection test terminal respectively to a voltage test signal and a connection test signal. The chip is couple to the at least one optical coupler circuit, and receives the connection test signal and the voltage test signal produced by the at least one optical coupler circuit, and determines whether the corresponding electrostatic tester connected to each optical coupler circuit is worked normally according to the connection test signal and the voltage test signal.
