Software Reliability Assessment with OR Applications

Effect of Test Coverage and Change Point on Software Reliability Growth Based on Time Variable Fault Detection Probability

“…Applications of testing coverage has been considered by many researches in software reliability growth modeling [1], [23]. Initially, Gokhale et al [17] proposed the NHPP based SRGM with testing coverage which is based on the following assumptions: 1) Software faults are distributed uniformly over potential fault sites.…”

“…They [17] have considered three types of fault coverage functions: exponential, Weibull and s-shaped, and concluded that the selection of testing coverage function will depend on criteria which fulfils the user's requirement. Latter, many SRGMs have been proposed based on the assumptions of Gokhale SRGM [1], [8].…”

“…Software testing is one of the major software development activity, which helps in improving the quality. The main objective of the software testing is to uncover and removed the inherent and introduced faults with minimum expenditure [1]. Software reliability is the essential part of a quality software, so it is necessary to enhance the reliability of the software.…”

“…The main objective of the testing coverage analysis is to find the fault sites which are uncovered and additional test cases required to increase the testing coverage. During the testing process, to detect the faults present at the fault sites, potential fault sites are sensitized [1], [17]. One common assumption of the most of the SRGM that the fault present at the potential fault sites are detected with constant probability [1], [8].…”

“…Moreover, different studies have been done considering the various behavior of the testing coverage such as exponential, Weibull, s-shaped etc. [1]. Gokhale et al [17] concluded that the selection of the coverage function depends on the criteria which fulfills the user's specific requirements.…”
