Unit Testing Model Management Operations

A model management workflow typically consists of a number of interdependent model-management tasks such as model validation, transformation, merging, comparison and text generation. As such workflows are becoming more and more complex, errors in individual tasks are likely to be propagated to subsequent tasks and eventually compromise the operation of the entire workflow. Therefore, building confidence about the correctness of each individual task before integrating them is becoming increasingly important. In this paper we present an approach to uniform unit-testing of individual model management operations and a prototype for specifying and executing test-cases, implemented atop the infrastructure provided by the Epsilon model management platform.
