The present disclosure provides an apparatus and system for testing a touch screen, and an apparatus for controlling test of a touch screen. The apparatus for testing a touch screen comprises: a processor, a test signal collection interface unit, and an external communication interface unit, wherein the processor is connected to the test signal collection interface unit, and is configured to, after touch information is collected by the test signal collection interface unit, convert the collected touch information into a format which is recognizable by an intelligent device, and transmit the converted touch information to the intelligent device through the external communication interface unit. The apparatus for testing a touch screen according to the present disclosure enables the touch information to be correspondingly processed and displayed by a processor and a display of the intelligent device, respectively. In this way, as the processor of the apparatus for testing a touch screen per se needs not to perform corresponding data processing and analysis processes, a processor with low performance may be used to facilitate reducing the manufacturing cost of the apparatus for testing a touch screen.
