Testing an open source suite for open queuing network modelling using metamorphic testing technique

Queuing network modelling is a modelling technique for capacity planning studies of computer and communication systems. Due to complexity of the technique, it is very difficult to know from the computed outputs whether the computation of the modelling software is correct. It is necessary to have an effective testing technique to address this problem. Recently, it has been noticed that metamorphic testing is an effective technique for this kind of problem. In this paper, we study the technique of metamorphic testing in testing queuing network modelling through a set of testing experiments in the Java Modelling Tool - a popular open source queuing network modelling suite.
