A COMPARISION STUDY ON RELIABILITY BASED TESTING TO MINIMIZE VARIANCE

Abstract Reliability is an anticipation of failure-free actions of a system over a stated time in a stated environment for a stated purpose. Blackbox testing is used for reliability estimation where the code is frozen. Reliability testing provides mechanism for making quantitative decision on reliability, about a process or processes . The main objective of this paper is to minimize variance in software reliability estimation.Reliability of a given software is inversely proportional to the variance.Various methods for estimating reliability are Operational Profile, Markov Chain, Controlled Markov Chain, Hidden Markov Chain etc.These methods are used in different types of testing strategy such as Operational Profile testing, Usage based testing, Adaptive testing, Modified adaptive testing etc.
