“…Hence, the role of behaviour specifications is to provide abstract test cases, test oracles, and a measure of the test adequacy [21]. Instead, the role of an inferred model is mainly to provide abstract test cases (e.g., [22,19,16]), to be instantiated in executable test cases by adding inputs and, eventually, test oracles (e.g., [16]). This instantiation is an expensive activity and the presence of infeasible test cases demand for substantial effort and knowledge from the tester's side, who is required to recognise them and filter them out.…”

“…FSM models have been exploited to generate test cases in several existing works [13,15,[19][20][21][22]16]. In case of a design-time model, abstract test cases can be used to check how the expected behaviours (coming from the model) have been implemented in the application [19,20].…”

Abstract. Model based testing offers a powerful mechanism to test applications that change dynamically and continuously, for which only some limited black-box knowledge is available (this is typically the case of future internet applications). Models can be inferred from observations of real executions and test cases can be derived from models, according to various strategies (e.g., graph or random visits). The problem is that a relatively large proportion of the test cases obtained in this way might result to be non executable, because they involve infeasible paths. In this paper, we propose a novel test case derivation strategy, based on the computation of the N -gram statistics. Event sequences are generated for which the subsequences of size N respect the distribution of the N -tuples observed in the execution traces. In this way, generated and observed sequences share the same context (up to length N ), hence increasing the likelihood for the generated ones of being actually executable. A consequence of the increased proportion of feasible test cases is that model coverage is also expected to increase.

“…JavaScript is the client side scripting, which can control the interaction between user and the web page by calling the XMLHttpRequest to request data to the server without disturbing the web page [4]. After the data is obtained from XMLHttpRequest, the JavaScript will be used to manipulate the contents of a web page in Document Object Model (DOM) [1].XMLHttpRequest is the main technology that makes Ajax engine able to request to the server and receive data from the server [10]. DOM is a structure within a web page, in which its content and visibility can be modified by using JavaScript [5].…”

Abstract-Green Ajax as a new approach in the web development has an aim to create interactive communication between server and client but avoiding the useless redundant requests. Some researches have been conducted to prove the benefit of Green Ajax, compared to Classic Ajax. The results of experiment show that the performance of Green Ajax is better than Classic Ajax in almost of all conditions. These results strengthen the conclusion that Green Ajax is a good approach in the web-based application development.However, some further researches have to be conducted in different environments to prove that the conclusion is also valid for a wider variety of conditions. One of those conditions is the wireless Local Area Network which is now very commonly available in schools, hotels, offices and business centers. Thus, the implementation of Green Ajax for the applications that support business, not just an experiment, can be realized immediately by using Randomized Cue Applications. This paper will focus on the analysis of Green Ajax performance on the wireless Local Area Network. The program discussed will demonstrate the ability of Green Ajax in providing a good interaction between users and the web server. The results of the experiment confirm that the Green Ajax is suitable for the applications on the wireless Local Area Network. Network traffic reduction is obtained as the final result in the use of Green Ajax.Index Terms-Green Ajax, network traffic, web-based application, wireless LAN. I. INTRODUCTIONGreen Ajax is an enhancement of Classic Ajax which has been recognized in the web application. Inheriting from the origin, Green Ajax also has the ability to decrease the bandwidth consumption by delivering data only in the specific part of web page [8]. The user interfaces will display any information without any interruption on screen because the communication between web application and server is done in the background.The improvement is located in the ability of web application to receive notification from the server whenever an update or a change of data occurs. When the application receives the server's cue, the application will then send out a request [7]. The applications will display the latest information without any involvement from the user. This method reduces required bandwidth below than necessary for data updating.In the previous experiments done in the wired Local Area Network, Green Ajax has been proven as a suitable approach for web-based application in variety conditions. When the server updates the data in unpredictable time, Green Ajax applications are always able to be a better approach in displaying the latest data. Green Ajax sends fewer requests to the server compared to Classic Ajax. The less bandwidth consumption of Green Ajax reduces the network traffic [7].Furthermore, Green Ajax is still able to display the latest data using smaller amount of requests than Classic Ajax even though the server updates the data at the scheduled time and Classic Ajax uses the same interval time of data up...

SUMMARYTesting GUI‐based applications is hard and time consuming because it requires exploring a potentially huge execution space by interacting with the graphical interface of the applications. Manual testing can cover only a small subset of the functionality provided by applications with complex interfaces, and thus, automatic techniques are necessary to extensively validate GUI‐based systems. This paper presents AutoBlackTest, a technique to automatically generate test cases at the system level. AutoBlackTest uses reinforcement learning, in particular Q‐learning, to learn how to interact with the application under test and stimulate its functionalities. When used to complement the activity of test designers, AutoBlackTest reuses the information in the available test suites to increase its effectiveness. The empirical results show that AutoBlackTest can sample better than state of the art techniques the behaviour of the application under test and can reveal previously unknown problems by working at the system level and interacting only through the graphical user interface.
