A keyboard testing system includes a processor-based test unit electrically coupled to a microprocessor of a keyboard to be tested to test and determine if the microprocessor function properly, at least one optic sensor which is controlled by the test unit to detect light emitted from LED indicators of the keyboard for testing the indicators and a key testing device which is controlled by the test unit to sequentially actuate keys of the keyboard for testing the keys. The key testing device includes at least one pneumatic cylinder to which an end effector is mounted. The pneumatic cylinder is controlled by the test unit to move the end effector toward/away from and thus actuating/de-actuating the keys. A conveying device moves the key testing device to each of the keys for testing each of the keys. Test results obtained in testing the microprocessor, the indicators and the keys of the keyboard are transmitted to the test unit which controls a warning device to generate a warning signal when a fault condition is determined based on the test results.
