A keyboard testing apparatus includes a housing inside which two clamping members spaced from each other at an adjustable distance for receiving a keyboard to be tested therebetween. A retaining device includes a pneumatic cylinder for applying force to the keyboard for firmly retaining the keyboard in position. An indicator testing device includes several optic sensors for detecting light emitted from indicators of the keyboard. A key testing device includes several key actuators capable to sequentially actuate/de-actuate the keys of the keyboard. A conveying device drives the key actuators relative to the keyboard in order to position the key actuators with respect to each key of the keyboard. A control unit, preferably a processor-based device, controls the operation of the key testing apparatus and receives test signals from the keyboard and the optic sensors to determine if the keyboard function normally. The control unit generates a warning signal via a warning device when the keyboard is abnormal. The control unit also stores information of the test result for further processing.
