1. A system for automated testing of a stylus, the system comprising:

  • a holder to receive the stylus;

    a detector to detect that the stylus is disposed in the holder;

    an actuator to move the holder;

    a touch panel to generate position data for a plurality of points of contact between the stylus and a surface of the touch panel; and

    a processing device coupled to the detector, the touch panel and the actuator, the processing device to;

    receive a detector signal from the detector indicating that the stylus is disposed in the holder;

    in response to receiving the detector signal, send a first actuator signal to the actuator to move the holder and the stylus across the surface of the touch panel along a linear path;

    receive position data from the touch panel for the plurality of points of contact between the stylus and the touch panel along the linear path; and

    determine that the position data corresponds to the linear path created by the actuator; and

    a mass fixture including one or more masses that are attachable to at least one of the holder or the stylus, wherein the processing device is further to;

    send a second actuator signal to the actuator to position the stylus beneath the mass fixture;

    send a mass fixture signal to the mass fixture to place the one or more masses onto the stylus; and

    receive pressure data from the touch panel indicative of a pressure applied by the stylus to the touch panel responsive to the one or more masses.
