Formalism-Driven Development: Concepts, Taxonomy, and Practice

Formal methods are crucial in program specification and verification. Instead of building cases to test functionalities, formal specify functionalities as properties mathematically prove them. Nevertheless, the applicability is limited most development processes due requirement mathematical knowledge for developers. To promote application methods, we formulate formalism-driven (FDD), which an iterative incremental process that guides developers adopt proper throughout whole lifespan. In FDD, system graphs, a variant transition systems optimized usability, designed model structures behaviors with representative properties. System graphs built iteratively incrementally via refinement. Properties specified propositional temporal logics verified by model-checking techniques interpretation over system. addition, skeleton programs generated based on expose implementable interfaces executing external algorithms emitting observable effects. Furthermore, present Seniz, framework practicalizes automates FDD. this paper, explicate concepts taxonomy FDD discuss its practice.
