Problems solved by technology

However, if the testers are inexperienced, or often because the display speed on the screen is too fast, the abnormality of the video graphics array output cannot be detected in a short time or the problem cannot be found at all.
[0004] This kind of manual testing method needs to be operated repeatedly according to the instructions and judged by the naked eye. Not only is the efficiency low, but it is also more likely to affect the test results due to human operation and judgment errors, thus increasing the test time or making the test coverage unable to improve. Production cost and product quality

Abstract

The invention relates to testing equipment with multiple testing ports and a testing method thereof. The testing equipment comprises a device to be tested and with an application program for product function testing, a micro-control unit platform, a universal sequence bus interface, a first video graphics array interface and a PS / 2 interface, wherein the universal sequence bus interface, the firstvideo graphics array interface and the PS / 2 interface are used for communicating the device to be tested with the micro-control unit platform. A testing signal sent by the application program for product function testing is transmitted to the micro-control unit platform to detect, and then a detection result of the micro-control unit platform is returned to the application program for product function testing.

Description

technical field [0001] The present invention relates to a multi-test port testing machine and its testing method, and in particular to a testing machine and its method for testing the output function of a video graphic array and the output / input function of a PS / 2 connection port. Background technique [0002] The peripheral devices of the computer can communicate with the host computer through respective connection protocols. Among them, the monitor can communicate with the host computer through the video graphics array (video graphics array; VGA) connection port, and the mouse and keyboard can communicate with the second generation system connection port (Personal System / 2 port; PS / 2 port) of the personal computer. Communicate with the host computer. [0003] In the manufacturing process, the output function test of the video graphics array and the output / input function test of the PS / 2 connection port mostly adopt the human-computer interaction test. Taking the video gr...
