Automated testing; reflection; metamodel; power- type; REA ontology

Ontologies have more then one level of the abstraction view. This ensures to create a precise model of the subject under study. Different level architecture requires using a specific model techniques such as power-type objects to represents object that exists on more then one level. Complex object structure makes hard to implement unit testing. This paper proposes a new approach to implement unit testing by using object metamodel. That makes unit testing fully automated and increase efficiency. The paper also proposes a required extension to JUnit framework and verifies the approach on the real model.
