A comprehensive framework to quantify fault tolerance metrics of web centric mobile applications

Applications well-defined with high Fault Tolerance index are considered reliable and trustworthy to drive quality. Fault Tolerance metrics for web mobile applications are neither defined formally nor are they organized at a single place for measurement to researchers and quality engineers. Fault Tolerance metrics determines the quality of web mobile applications provided they are measured accurately. There is a phenomenal gap between Fault Tolerance (FT) metrics development and measurement for web based mobile applications. Unfortunately, existing research has failed in providing a precise and well-organized definition for Fault Tolerance metrics in the domain of web mobile applications. This has led to inadequate Fault Tolerance metrics to perfectly measure and benchmark modern day web mobile applications. This research work has developed a comprehensive Fault Tolerance Metrics Framework, targeting Web and Mobile Applications to measure associated quality attributes by applying GQM technique. Dispersed FT attributes are identified and organized from existing Quality Models and standards. Sub factors have been well defined using standard units in line with web architectures. Particularly, this research applies Systematic Mathematical formulation to quantify Fault Tolerance to target web mobile applications. Further Fault Tolerance is measured and evaluated through an experimental study designed on target web mobile applications.
