Method and system for testing machine top box based on serial port communication

Abstract

The invention relates to a method and a system for testing a machine top box based on serial port communication. The method comprises the following steps: (a) constructing an independent monitoring line range; (b) constructing annular queues which are connected from the beginning to the end and storing the input testing information; (c) starting a machine top box, initializing and communicating with a computer by a serial port; (d) referring the serial port to output aid prompting information, setting a testing item by operating a remote controller, recording the input key value and the inputkey time by the monitoring line range of the serial port and forming a testing path which is placed in the annular queues; (e) inputting a command of 'starting automatic testing' by the serial port, carrying out sequence circulation scanning on each node of the whole queue after receiving and affirming the command by the monitoring line range, and delivering the scanned key value sequentially intothe system of the machine top box according to the calculated time interval; (f) monitoring the testing information input by keys by the system of the machine top box and running a corresponding function module to the testing path set by the testing personnel by different received testing information; and (g) outputting a testing result to a computer screen by the serial port. The invention can carry out automatic testing, has simple operation and is beneficial to discovering a latent defect existing in software and enhancing the stability of a product.

Description

technical field [0001] The invention relates to a test system of a set-top box, in particular to a set-top box test method and system based on serial communication. Background technique [0002] With the increasing development of digital TV services, the functions of set-top boxes are becoming more and more complex, and customers have higher and higher requirements for the quality of set-top box products. Therefore, the quality testing and control of software products is gradually becoming the core of the survival and development of software companies. [0003] At present, testers mainly rely on manual testing of set-top box products. According to customer requirements, testers manually operate the remote control to verify whether the functions of the set-top box are normal according to the requirements specification. Sometimes according to needs, the set-top box will be placed under a specific program for continuous playback, and a long-term aging test will be carried out. ...

Problems solved by technology

[0004] Analyzing the above-mentioned existing testing methods, it is found that there are several disadvantages as follows: Many manual testing methods are used, and their testing strength and flexibility have great limitations. Even if a long-term aging testing strategy is adopted, it is only for It is a kind of static test for program playback function. This manual test method is far from enough in terms of test intensity, and it is not easy to find potential defects in the software. Moreover, its test efficiency is not high; some existing automatic tests This method has certain technical requirements for operators, and there are many disadvantages in its portability and flexibility in actual operation.
