1. A method, comprising:

  • testing a touch-sensitive surface of a touchscreen device by;

    receiving at the touch-sensitive surface a contact;

    detecting the contact by both a first sensor part of the touch-sensitive surface and a second sensor of a test apparatus, the second sensor being an acoustic sensor, the first sensor being a type other than acoustic, the touch-sensitive surface not containing an acoustic sensor usable to detect the contact, and the second sensor being separate and distinct from the touchscreen device and not used by the touchscreen device to detect the contact;

    sending first data from the touchscreen device to the test apparatus, the first data describing the contact as detected by the first sensor; and

    determining an ability of the touchscreen surface to accurately detect the contact by comparing the first data to second data, the second data describing the contact as detected by the second sensor.
