Method for testing keyboard-free and screen-free equipment

Abstract

The invention relates to a method for testing keyboard-free and screen-free equipment. The method comprises the following steps: 1) physically connecting a POS machine with a PC through a serial portline; 2) running a test program, and executing an operation of opening the serial port by the test program; 3) opening serial port tool software, and opening a serial port; 4) when the test code needsto output the information, exeucting a serial port writing operation by the test program, and uploading a test result and the information required in the test process to an output display area of theserial port tool software; and (5) when key input is needed in the test process, inputting characters expected by the test program by the PC keyboard, sending the input characters to the POS machineby the serial port tool software, executing serial port reading operation by the POS terminal, and after the test program reads data, executing corresponding operation according to the read data.

Description

technical field [0001] The invention is applicable to the testing of the equipment without the keyboard and without the screen, and is a testing method proposed for the equipment without the keyboard and without the screen. Background technique [0002] POS machines play a vital role in the payment field, and the quality of POS machines must be strictly checked. With the continuous development of science and technology, the forms of POS machines are becoming more and more diversified, one of which is without a keyboard and without a screen, such as the common code scanning box and iPOS in daily life. [0003] For the test of this kind of device without keyboard and without screen, the difficulty is that when the test program is running on the POS terminal, the tester cannot visually observe the test results on the screen, and cannot control the execution of the test program through key operations. [0004] Currently testing on such a device with no keyboard and no screen, B...
