Using Scenario-Based Reading for Testing Mobile Applications with FIT4Apps

The need for effective quality assurance methods for mobile applications has led to the development of the quality assurance method FIT4Apps (Focused Inspection and Testing for Apps). This paper reports on the controlled experiment used to evaluate it. The experiment was performed with 21 participants, who performed state-of-the-practice quality assurance as a control treatment and additionally used FIT4Apps as an experimental treatment. The results of the controlled experiment showed that the use of FIT4Apps during development leads to significantly more mobile-specific failures being found, respectively prevented. The controlled experiment revealed that these findings represent 11.5% of the overall failures and that 0.3% of the overall development effort is necessary for using FIT4Apps. Overall, the experiment showed that FIT4Apps is useful and effective for reducing failures. In addition, we evaluated FIT4Apps in an expert survey regarding the acceptance of the method. The results show that the method is promising for use by practitioners.
