Measuring Reliability of A Web Portal Based on Testing Profile

Abstract

Conventionally, the reliability of a web portal is validated with generalized conventional methods, but they fail to provide the desired results. Therefore, we need to include other quality factors that affect reliability such as usability for improving the reliability in addition to the conventional reliability testing. Actually, the primary objectives of web portals are to provide interactive integration of multiple functions confirming diverse requirements in an efficient way. In this paper, we employ testing profiles to measure the reliability through software operational profile, input space profile and usability profile along with qualitative measures of reliability and usability. Moreover, the case study used for verification is based on a web application that facilitates information and knowledge sharing among its online members.The proposed scheme is compared with the conventional reliability improvement method in terms of failure detection and reliability. The final results unveil that the computation of reliability by using the traditional method (utilizing failure points with the assistance of Mean Time Between Failures (MTBF) and Mean Time To Failure (MTTF) becomes ineffective under certain situations. Under such situations, the proposed scheme helps to compute the reliability in an effective way. Moreover, the outcomes of the study provide insight recommendations about the testing and measurement of reliability for Web based software or applications.
