The selection of appropriate test cases is an important issue for conformance testing of protocol implementations as well as in software engineering. A number of methods are known for the selection of a test suite based on the specification of the implementation under test, assumed to be given in the form of a finite state machine. This paper presents a new(More)
In the area of testing communication systems, the interfaces between systems to be tested and their testers have great impact on test generation and fault detectability. Several types of such interfaces have been standardized by the International Standardization Organization (ISO). A general distributed test architecture, containing distributed interfaces,(More)
In this paper, we propose a generalized diagnostic algorithm for the case where more than one fault (output and/or transfer) may be present in the transitions of a system represented by a deterministic finite state machine (FSM). If existing faults are detected, this algorithm permits the generation of a minimal set of diagnoses, each of which is formed by(More)
We propose a diagnostic algorithm for the case where a distributed system specification (implementation) is given in the form of communicating finite state machines (CFSMs). Such an algorithm localizes the faulty transition in the distributed system once the fault has been detected. It generates, if necessary, additional diagnostic test cases which depend(More)
