Usage testing of military simulation systems

Scalability and input domain explosion make it impossible to exhaustively test simulation systems. Improved methods such as statistical usage testing are needed to provide quantitative support for test planning and test management. This paper describes the challenges and the state! of the practice of testing simulation systems. A brief introduction to statistical usage testing is provided. An approach to developing an abstract usage model structure appropriate for testing military simulation systems is suggested and illustrated. This approach supports the creation and analysis of test scenarios that are flexible enough to handle a wide range of uses in military simulations.
