“…Various arguments have been used to determine the test duration in discrete time, that is, to determine a lower bound on the number N of test inputs required to ensure that P, the actual failure probability per execution, is less than or equal to a value Po with a given confidence level. In [18,27,38) the authors make use of relations similar to equation (1), and in [9,14) the classical theory of hypothesis testing is called upon. All of these studies, however, lead to relation (2) in which QN corresponds to the confidence level [39).…”

“…Assuming that the failure process is governed by a constant hazard rate (the failure occurrences conform to a Poisson distribution), the evaluation in continuous time yields a similar formula. The testing time T required to ensure that the software meets a failure rate Ao with a confidence level (I-Eo), see for example [13,18], is:…”

“…Correlated errors form a main source of failure of the N-version programs. Correlated errors can be minimized by design diversity [14,15,302]. A design paradigm has been developed to assure design diversity in N-version software [221].…”

“…Solche gemeinsamen Fehlreaktionen sollten zumindest wesentlich seltener sein als die Fehlreaktion eines Programmes allein. (Für Abnahmetests kann man sich mit einer schwächeren Forderung begnügen, so daß die folgende Kritik diesen Fall nicht betrifft [7].) Aufgrund von Korrelationsbestimmungen sind Zweifel an der Basisannahme laut geworden.…”
