В данной статье мы предлагаем метод построения проверяющих тестов с гарантированной полнотой для полностью определенного, возможно, недетерминированного автомата с одной временной переменной. Такие временные автоматы используются при описании поведения программного обеспечения и цифровых устройств. Область неисправности содержит все полностью определенные автоматы с заданным числом состояний и известной верхней оценкой на интервалы, описывающие временные ограничения. Предлагаемый метод опирается на построение по заданному временному автомату соответствующей конечно автоматной абстракции (абстрактного автомата). По абстрактному автомату строится проверяющий тест, последовательности которого суть временные входные последовательности. Более короткие тесты можно построить, если ввести дополнительные ограничения на область неисправности, например, для случая, когда известна наименьшая продолжительность каждого временного интервала в тестируемой реализации, и её величина больше двух. Кроме того, тест можно сократить с сохранением его полноты в случае, когда все интервалы для временных ограничений закрыты справа (или все интервалы закрыты слева). Приводятся результаты проведенных компьютерных экспериментов по сравнению длин тестов, построенных по временному автомату различными методами. </p></abstract><trans-abstract xml:lang="en"><p>Nowadays, the behaviour of many systems can be properly described by taking into account time constraints, and this motivates the adaptation of existing Finite State Machine (FSM)- based test derivation methods to timed models. In this paper, we propose a method for deriving conformance tests with the guaranteed fault coverage for a complete possibly nondeterministic FSM with a single clock; such Timed FSMs (TFSMs) are widely used when describing the behaviour of software and digital devices. The fault domain contains every complete TFSM with the known upper bounds on the number of states and finite boundary of input time guards. The proposed method is carried out by using an appropriate FSM abstraction of the given TFSM; the test is derived against an FSM abstraction and contains timed input sequences. Shorter test suites can be derived for a restricted fault domain, for instance, for the case when the smallest duration of an input time guard is larger than two. Moreover, the obtained test suites can be reduced, while preserving the completeness, when all input time guards of the specification and an implementation are right closed (or all intervals are left closed). Experiments are conducted to study the length of test suites constructed by different methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>временные автоматы</kwd><kwd>недетерминированные автоматы</kwd><kwd>синтез тестов</kwd><kwd>область неисправности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>timed finite state machines</kwd><kwd>nondeterministic finite state machines</kwd><kwd>test derivation</kwd><kwd>fault coverage</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chow T.
