Why is it important to verify/validate model transformations? The motivation is to improve the quality of the transformations, and therefore the quality of the generated software artifacts. Verified/validated model transformations make it possible to ensure certain properties of the generated software artifacts. In this way, verification/validation methods can guarantee different requirements stated by the actual domain against the generated/modified/optimized software products. For example, a verified/ validated model transformation can ensure the preservation of certain properties during the model-to-model transformation. This paper emphasizes the necessity of methods that make model transformation verified/validated, discusses the different scenarios of model transformation verification and validation, and introduces the principles of a novel test-driven method for verifying/validating model transformations. We provide a solution that makes it possible to automatically generate test input models for model transformations. Furthermore, we collect and discuss the actual open issues in the field of verification/validation of model transformations.

A worthy contribution of this paper is for that strategic target. The field of verification and validation is quite hot in software building community because undetected software bugs cost typically a huge amount of money and time for businesses. Not only to nip in the budding stage, but also to substantially increase the quality of transformation through effective verification and validation procedures. Here too, the need for automation is being mandated in order to easily and quickly do verification and validation tasks. Authors discussed the model transitions very clearly and deeply, emphasized the necessity of viable and value-adding methods that make model transformation verified/validated, discussed the different scenarios of model transformation verification and validation, and finally introduced the principles of a test-driven method for verifying/validating graph rewriting-based model transformations.
