摘要：AbstractComplete conformance testing is a model-based test technique for programmable controllers. It checks whether an implementation conforms to its specifications with regard to all possible combinations of input signals, which is useful for small scale and safety critical systems. However, thestate space explosionissue limits its application to large scale systems. This paper presents a method for reducing state space in generation of test cases by utilizing not only specification models but also features extracted from plant models. The application on a benchmark case study shows that the number of test cases is reduced significantly.
