Source Code Online Judging Based On Black-Box Testing

With the fast developing of computer technology and the increasing high requirement of programming level, program design is a required course for college students. In teaching, it is necessary to judge the program quickly and correctly, and then give the result to students. But in the teaching field, the traditional program judging method is manual, which disadvantage is need lots of time. It is not only add the burden of the teacher, but also the student can't get the result in time and don't know whether the program can run correctly or not. The second disadvantage is the factor of people is very large. The same program gets different score which judged by different people. In fact, the same judger may be gave the same program different score with him or hers mood and other factor. In order to advance student's programming level and lighten the burden of teacher, this paper combines the characteristic of black-box testing and advantage of online system, designing a source coder online judging system which is used for aided instruction. This system is applicable for instruction, contest, exam and exercise. This paper introduce the background and status of source code online judging, the meaning of research, the key technology of system implement, including B/S frame, .NET platform, black-box testing and dynamic link library and the whole design and implement of the key parts. In the final the author brings forward a new idea about this system.
