Abstract
This paper presents an HTML5 mobile test (mTest) application for use in an agent-based mobile eLearning (mLearning) system. The application was developed based on the Sencha Touch framework. The mTest application receives XML data from a personal assistant agent on the client side and can work in different mobile operating system environments, such as iOS, Android, BlackBerry, Windows Phone, etc. The application is designed by means of the Model View Controller (MVC) design pattern, and is easy to maintain, test, and extend. Moreover, the mTest session is stored on the mLearning server side, which facilitates the handover from one user device to another during the service session, and enables an always best connected and best served (ABC&S) communication mode.
