Testing Timed Nondeterministic Finite State Machines with the Guaranteed Fault Coverage

Abstract: получена 22 декабря 2016Аннотация. В настоящее время при описании поведения дискретных систем достаточно часто необходимо принимать во внимание временные аспекты, и соответственно появляется необ-ходимость в распространении автоматных методов синтеза тестов с гарантированной полнотой на временные автоматы. В данной статье мы предлагаем метод построения проверяющих тестов с гарантированной полнотой для полностью определенного, возможно, недетерминированного авто-мата с одной временной переменной. Такие временны… Show more

“…In the worst case, the length of a test suite derived by SCR-method exponentially depends on the number of states of FSM and this also holds for FSM with timed aspects. As experimental results show, in practice, length of adaptive distinguishing sequences is usually polynomial with respect to the number of FSM states when such a sequence exists [20,7]. Respectively, similar results can be derived for a TFSM when proposed algorithm is used and the boundary on timed guards is not too big.…”

“…Respectively, similar results can be derived for a TFSM when proposed algorithm is used and the boundary on timed guards is not too big. Note that length of the test suite also significantly depends on timed aspects of the specification TFSM such as the upper bounds of timed guards and value of timeouts [20,21]. We note again that the FSM abstraction of TFSM S can have non-separable states while all states of the TFSM are pairwise separable.…”

“…Известный подход к построению конечно-автоматной абстракции сопровождается существенным увеличением входного алфави-та или множества состояний относительно исходного временного автомата [23]. Поскольку такая абстракция является избыточной при решении ряда задач [21,25,26], в том числе задач, связанных с установочными и тестовыми последовательностями, мы предлагаем подход к оптимизации конечно-автоматной абстракции.…”
