Инкрементальный подход к технологии создания тестов для индустриальных проектов

The paper presents an approach to effort reduction in developing test suites for industrial software products based on the incremental technology. The main problems to be solved by the incremental technology are full automation design of test scenarios and significant reducing of test explosion. The proposed approach provides solutions to the mentioned problems through joint co-working of a designer and a customer, through the integration of symbolic verification with the automatic generation of test suites; through the usage of an efficient technology with the toolset VRS/TAT.Статья посвящена описанию технологии, позволяющей сократить трудозатраты на создание тестов для промышленных программных проектов, за счет использования инкрементального подхода. Основная проблема, решенная в данной работе, связана с полной автоматизацией фазы дизайна тестовых сценариев и сокращением количества тестов, необходимых для обеспечения качества программного продукта. Предлагаемая в работе технология позволяет решить указанные проблемы за счет совместной работы дизайнера тестовых наборов и заказчика с использованием формальных моделей, методов символьной верификации и автоматической генерации тестовых наборов на базе использования инструментария VRS/TAT

The Design and Analysis of Real-Time Systems Using the ASTRAL Software Development Environment

ASTRAL is a formal specification language for real-time systems. It is intended to support formal software development and, therefore, has been formally defined. The structuring mechanisms in ASTRAL allow one to build modularized specifications of complex systems with layering. A real-time system is modeled by a collection of state machine specifications and a single global specification. This paper discusses the ASTRAL Software Development Environment (SDE), which is an integrated set of design and analysis tools based on the ASTRAL formal framework. The tools that make up the support environment are a syntax-directed editor, a specification processor, a verification condition generator, a browser kit, a model checker, and a mechanical theorem prover
