abstract = {Formal specifications provide strong bases for testing and bring powerful techniques and
technologies. Expressive formal specification languages combine large data domain and behavior. Thus,
symbolic methods have raised particular interest for test generation techniques. Integrating formal
testing in proof environments such as Isabelle/HOL is referred to as "theorem-prover based testing".
Theorem-prover based testing can be adapted to a specific specification language via a representation
of its formal semantics, paving the way for specific support of its constructs. The main challenge of
this approach is to reduce the gap between pen-and-paper semantics and formal mechanized theories. In
this paper we consider testing based on the Circus specification language. This language integrates
the notions of states and of complex data in a Z-like fashion with communicating processes inspired
from CSP. We present a machine-checked formalization in Isabelle/HOL of this language and its testing
theory. Based on this formal representation of the semantics we revisit the original associated
testing theory. We discovered unforeseen simplifications in both definitions and symbolic
computations. The approach lends itself to the construction of a tool, that directly uses semantic
definitions of the language as well as derived rules of its testing theory, and thus provides some
powerful symbolic computation machinery to seamlessly implement them both in a technical environment.
