Abstract:

Recent approaches to automated testing of computerized survey instruments have emphasized model-based testing procedures, where a specific survey is represented graphically as a series of arcs and nodes. Progress through the survey can then be simulated using Markov chain Monte Carlo methods for graphical models. "Intelligent" randomization using this approach greatly improves the efficiency and coverage of the testing process. We discuss our experience with automated model-based testing using NaQuest, survey software that can be used for web and other self-administered survey modes.
