This paper extends dynamic symbolic execution to distributed and concurrent systems. Dynamic symbolic execution can be used in software testing to systematically identify equivalence classes of input values and has been shown to scale well to large systems. Although mainly applied to sequential programs, this scalability makes it interesting to consider the technique in the distributed and concurrent setting as well. In order to extend the technique to concurrent systems, it is necessary to<span class="external-identifiers"> <a target="_blank" rel="external noopener noreferrer" href="https://doi.org/10.1007/978-3-642-02949-3_9">doi:10.1007/978-3-642-02949-3_9</a> <a target="_blank" rel="external noopener" href="https://fatcat.wiki/release/ky5eoxobxfg6he6zf3w6a2hbea">fatcat:ky5eoxobxfg6he6zf3w6a2hbea</a> </span>

Creol, a modeling language for distributed concurrent objects, solves this problem by abstracting from a particular scheduling policy but explicitly defining scheduling points. This provides sufficient control to apply the technique of dynamic symbolic execution for model based testing of interleaved processes. The technique has been formalized in rewriting logic, executes in Maude, and applied to nontrivial examples, including an industrial case study. This research was carried out as part of the EU FP6 project Credo: Modeling and analysis of evolutionary structures for distributed services (IST-33826).
