Method for testing PS/2 interface

Abstract

The invention discloses a method for testing a PS / 2 interface, which comprises the following steps: connecting a test module with the PS / 2 interface and a USB interface of a tested host computer; starting the test module and the tested host computer and initializing the USB interface equipment and PS / 2 interface equipment of the tested host computer; allowing the tested host computer to send a command to the test module through the USB interface to require the test module to simulate the action of the PS / 2 interface equipment; making the test module simulate a PS / 2 protocol according to the command sent by the tested host computer and send a corresponding PS / 2 signal to the PS / 2 interface of the tested host computer; and allowing the tested host computer to receive the corresponding PS / 2 signal through the PS / 2 interface to judge if the communication of the PS / 2 interface is normal. The method can replace the traditional manual test method and improve test efficiency and precision.

Description

technical field [0001] The present invention relates to a testing method of a PS / 2 interface, in particular to a testing method for simulating the action of a PS / 2 interface device through a testing module so as to complete the testing of the PS / 2 interface of a host computer under test. Background technique [0002] At present, the existing PS / 2 interface testing method is done manually. For example, the test program prompts the tester through the screen to operate the specified external PS / 2 interface device according to the screen display, such as clicking the mouse or keyboard input, and then testing the program. Read the appropriate test input to determine if the interface to a PS / 2 interface device such as a keyboard or mouse is functioning properly. [0003] However, the PS / 2 interface testing method in the prior art still has defects, especially the test results are easily affected by the artificial operation of the testers, so the test accuracy is difficult to guara...

AI Technical Summary

Problems solved by technology

[0003] However, the prior art PS / 2 interface test method still has defects, especially the test results are easily affected by the tester's artificial operation, so the test accuracy is difficult to guarantee

[0004] In addition, the testing efficiency of manual operations is not high, and it is difficult to meet the testing requirements in mass production
