Software Testing of a Web-Based Apps for Human Vital Signs Monitoring System

Abstract

Recent rapid advancement of telecommunications technology, contemporary software applications are easily accessible. Many individuals utilize applications, such as web or mobile apps, for information retrieval, financial transactions, entertainment, and healthcare purposes. An example application undergoing development is the Patient Monitoring App, a custom-made system designed to monitor an individual's health based on the Early Warning Score (EWS) system. Given the crucial role of software testing in the Software Development Life Cycle (SDLC), functional testing is imperative to identify and rectify potential issues in the app's development process. This study focuses on enhancing the application through meticulous functional testing, employing step-by-step test cases and usability tests using the System Usability Scale (SUS) to gauge user satisfaction levels. The overall functional test is promising where only 12 operations from 65 test cases (18.5%) for caretaker accounts and 12 operations from 67 test cases (17.9%) for admin accounts failed to meet the expected outcomes. This implies the functionality of the caretaker account is 81.5% and the functionality of the admin account is 82.1%. Notably, there were no discernible differences in performance across popular web browsers, namely Google Chrome, Microsoft Edge, and Mozilla Firefox. Usability tests involving 12 caretaker account respondents reveal an average total score of 68 out of 100, meeting the minimum acceptable value. In summary, functional testing has been instrumental in identifying errors and providing suggestions for app enhancement, while usability tests offer valuable insights into user satisfaction. Emphasizing quality as a top priority, both tests serve as reliable indicators and guides for improving functionality and usability in the Patient Monitoring App.
