Modeling and Testing Multi-Threaded Asynchronous Systems with Creol

Modeling concurrent systems and testing multi-threaded implementations against the model is an exciting field of study. This paper presents work done on constructing and executing test cases for an industrial-size multi-threaded application against a model written in the Creol modeling language. Models written in Creol, an object-oriented, concurrent modeling language, can be structurally similar to the finished implementation; we show how to keep this desirable property when re-using Creol models as test oracles. Also, a conformance relation between model and system under test that needs less controllability than other relations that are based on automata is presented.
