Search-based testing of AjaxWeb applications

Ajax is an emerging Web engineering technology that supports advanced interaction features that go beyond Web page navigation. The Ajax technology is based on asyn-chronous communication with the Web server and direct manipulation of the GUI, taking advantage of reflection.Correspondingly, new classes of Web faults are associated with Ajax applications.In previous work, we investigated a state-based testing approach, based on semantically interacting events. The main drawback of this approach is that exhaustive genera-tion of semantically interacting event sequences limits quiteseverely the maximum achievable length, while longer se-quences would have higher fault exposing capability. In this paper, we investigate a search-based algorithm for the exploration of the huge space of long interaction sequences,in order to select those that are most promising, based on a measure of test case diversity.©2009 IEEE.
