Abstract

This chapter explores the relationship between testing and refinement. In particular, it looks at how tests for a refinement can be derived from tests for the abstract system. We discuss both how to derive tests from a formal specification, and also how tests can be refined for use with an implementation. We also consider how concrete tests can be calculated from abstract ones for refinements which are downward or upward simulations.
