The effect of testing on reliability of fault-tolerant software
Previous models have investigated the impact upon diversity - and hence upon the reliability of fault-tolerant software built from 'diverse' versions - of the variation in 'difficulty' of demands over the demand space. These models are essentially static, taking a single snapshot view of the system. In this paper, we consider a generalisation in which the individual versions are allowed to evolve - and their reliability to grow - through debugging. In particular, we examine the trade-off that occurs in testing between, on the one hand, the increasing reliability of individual versions, and on the other hand the possible diminution of diversity.
