Abstract

Testing or model-checking an open reactive system often requires generating a model of the environment. We describe a static analysis for Java that computes a partition of a system's inputs: inputs in the same equivalence class lead to identical behavior. The partition provides a basis for generation of code for a most general environment of the system, i.e., one that exercises all possible behaviors of the system. The partition also helps the generated environment avoid exercising the same behavior multipletimes. Many distributed systems with security requirements can be regarded as open reactive systems whose environment is an adversary-controlled network. We illustrate our approach by applying it to a fault-tolerant and intrusion-tolerant distributed voting system and model-checking the system together with the generated environment.
