Model Abstraction for Testing of Physical Systems
In: Eigth International Workshop on Qualitative Reasoning (QR-94), Nara, Japan, 1994.
We present a formal theory of model-based testing and an algorithm for test generation based on it, and outline how testing is implemented by a diagnostic engine. The key to making the complex task of test generation feasible for systems with continuous domains is the use of model abstraction. Tests can be generated using manageable finite models and then mapped back to a detailed level. We state conditions for the correctness of this approach and discuss the preconditions and scope of applicability of the theory.
