Design And Implementation Of The Test Software For LED Information Publishing System

With the continuous development of computer technology, traffic field gradually transform into intelligent transportation. LED information publishing system is a new generation of intelligent transportation products, which combines computer technology, communication technology, image display technology, and achieve a variety of complex transmission control user needs and display requirements, it has very broad application prospects. LED information publishing system is mainly to achieve the timely release of information by writing computer software program, but with the increasing degree of system integration, LED information publishing system software whose size and complexity is growing has become the focus of the project.Now, software test throughout the software development process is also more important. Therefore, the study of the test tool software development technology becomes more important, there are many development model, developers can also choose a variety of scripting languages, and improve the test scripts can reduce test time and increase work efficiency.What I mainly do in this paper, is to design a PC testing software instead of manually editing the sent message information for LED displays in the field of intelligent transportation of LED information publishing system and to implement all functions by code. Specific work is as follows:1. By the means of reviewing literature and reading technical material of current development process of software testing technology, I understand the today’s mainstream software testing techniques and test script language;2. I written test software based on.Net Framework 4.0 using the C# language and implement all functions.describing the functions of classes in details and list key code snippets, reducing the manual testers edit messages test of time;3. Reviewing literature of dynamic link library technology and its application;4. This paper describes the normal arrangement of LED information publishing system, the main equipment and their role, it explains what the protocols with LED contain.Results of this paper has been formed into products, Operational staff provide feedback that the software achieves all intended functions, is easy to use, and works well, meets with no abnormal condition. This software plays a positive role in the operation of stations and next researches..
