A circuit board testing system includes a testing fixture. The testing fixture is used for testing plural wires of a cable of a circuit board. The testing fixture includes a first contact element, a switch circuit, a second contact element, a voltage acquisition element and a control unit. The first contact element is connected with input terminals of the plural wires. The second contact element is connected with output terminals of the plural wires. When the control unit drives a switching action of the switch circuit, a testing voltage is provided to the odd-numbered wires or the even-numbered wires. The control unit reads the voltage values of the odd-numbered wires and the voltage values of the even-numbered wires from the voltage acquisition element so as to judge whether the plural wires of the cable are normal.
