Artefacts of modelling such as formal specifications and UML diagrams have a propensity to become rapidly and silently obsolete when implementation starts, which means that design traceability is often an early casualty in software engineering projects. JSizzle is a tool and a language, but most importantly an approach, for encoding model-level abstractions that are independent of implementation but allow Java code to be mapped to them using simple Java adapters. This then opens up the possibility of checking whether the code corresponds to the model at runtime and during unit tests. There’s no magic to be found in the principle, to model in a language that compiles down to Java. However there's some trickery in the tool implementation, which will offer tangential interest.

This talk will introduce the concept and the tool with a live demonstration, and show how modelling need not be the perpetual bridesmaid to code and test.
