Design and Application of a Response-Driven Adaptive Test System

Unlike the traditional paper-and-pencil tests, computer adaptive testing (CAT) presents the next item based on his or her past responses, which is more appropriate for a particular individual. However, it is rarely seen in a smaller-scale scenario, such as in classrooms or business, because of the complexity of Item Response Theory (IRT) and the possible usages of services may not be known or may increase due to the development of new services. Our approach to this problem is self-adaptive functional testing, which is a combination of monitoring and active testing at runtime. We present a Response-Driven Adaptive Test System (RDATS) to get userpsilas response data which has been detected during monitoring, existing test cases are adapted automatically to the specific situation and applied afterwards based on userpsilas response at runtime. In this paper, we discuss the structure and functionality of the system with particular emphasis on adaptive test Mechanisms and SQL database design. Finally, we discuss some practical issues related to the application of the system and its future works.
