In the domain of concurrent reactive systems, much work has been devoted to (semi-)automatically validating a system's correctness. In this paper a novel approach to the automated generation of test sequences is presented. It may be used for both glass box testing a specification and black box testing an implementation (software/hardware). Finite system models specified within the CASE tool AUTOFOCUS as well as user-friendly test case specifications are automatically translated into propositional logic and fed into the propositional solver SATO. Results are interpreted as input/output traces (test sequences) of the system, and may be displayed as message sequence charts. A small example illustrates the basic ideas as well as the method's advantages and shortcomings. The testing process is integrated into an overall development process. Main contributions include the implementation of a tool for graphical specification of test cases and the description of an efficient method to compute test sequences fully automatically as well as its integration into the same CASE tool.
