In order to address the continuing demand for high quality Low cost reliable software, Hundreds of software reliability growth models (SRGMs) have been proposed in recent years. In spite of the diversity and elegance of many of these, no single model can be readily recommended as best to represent the challenging nature of the software testing. Of late, some authors have tried to develop a unif...

There is evidence showing that HPA axis responses to pharmacological provocation depend on time of day with larger cortisol responses in the afternoon and evening compared to the morning hours. However, it is still unknown whether HPA axis responses to psychological stress are affected by time of day and whether they can be assessed with equal reliability in the morning and afternoon, respectiv...

A newly developed software system is subjected to vigorous testing before its deployment. Testing aims at minimizing the probability of occurrence of failures. The aim of testing process is to build confidence in the software for its use in real world applications. Thus, reliability of systems is always an important issue for us. Growth in reliability takes place as the error detection and corr...

Software reliability in the software development process is an important issue. Software process improvement helps in finishing with reliable software product. Infinite failure NHPP software reliability models presented in the literature exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this study, reliability software cost model consid...

Software reliability is one of the key attributes to determine the quality of a software system. Finding and minimizing the remaining faults in software systems is a challenging task. Software reliability growth model (SRGM) with testing-effort function (TEF) is very helpful for software developers and has been widely accepted and applied. However, each SRGM with TEF (SRGMTEF) contains some und...

Software reliability deals with behaviour of a software system in operation and it is defined as the probability of working without failure for a specified interval of time. In a number of recent disasters the computer has been wholly or partially to blame. In Ref. [1] an alarm signal is given by the following message: "Sometime soon, software reliability is going to become a highly visible and...

Prevalent approaches to software reliability modeling are black-box based, i.e., the the software system is treated as a monolithic entity and only its interactions with the outside world are modeled. However, with the advancement and widespread use of object oriented systems design and web-based development, the use of component-based software development is on the rise. Software systems are b...

We present a fast and exact algorithm to compute maximum likelihood estimates for the number of faults initially contained in a software, using the hypergeometric software reliability model. The algorithm is based on a rigorous mathematical analysis of the growth behavior of the likelihood function for the model. We also clarify the stochastic process underlying the model and prove a recursion ...

In software development life cycle, software testing is one of the most important tasks; and in the testing, software reliably is very important aspect for any category of software systems. A number of testing-effort functions for software reliability growth model based on non-homogeneous Poisson process (NHPP) have been proposed in the past. Although these models are quite helpful for software...

In the real-world environment web applications are rapidly developed. To depend upon this web applications information transformation can be easily upgraded, thru certain networking environment depending upon software and hardware can be used. The aim of web application is the customer satisfaction; due to this factor such applications can be majorly dependent on reliability fact. The reliabili...
