A test system for testing a capacitive touch sensor is provided. The test system includes a resistor, a signal generator and a micro controller. A first end of the resistor is electrically connected to a sensing port of the capacitive touch sensor. The signal generator provides a test voltage to a second end of the resistor according to control information. In this way, the resistor generates a test current according to the test voltage, and the capacitive touch sensor provides a voltage difference to the sensing port according to a plurality of switching signals, and converts the test current into test information. The micro controller generates the control information according to a test table, and compares the test information according to the test table, so as to determine whether an operation of the capacitive touch sensor is normal.
