An automated metamorphic testing technique for designing effective metamorphic relations

Abstract

Creation of metamorphic relations, and building up a dynamic system to carry out automated metamorphic testing has been aimed. Modeling notation has been adopted to design and extract metamorphic properties of the system, which have been tested during run time. Real time data for system execution has been used to generate follow up test data. Thus, parallel execution and testing system properties helps to achieve reduction in testing cost and effort. The complete methodology and its effectiveness for testing systems for which no reliable test oracle exists, has been demonstrated with the help of suitable case study, and the results have been verified. © 2012 Springer-Verlag.
