Abstract: The paper formalizes two types of refinement for finite state machines: OR refinement and p-OR refinement. For each such type of refinement, it shows that, if the implementation is also constructed through a process of refinement, then the application of Chow's W test generation method can be distributed into smaller chunks, thus diminishing the effort devoted to testing and the size of the final test set.
