Software testing automation is one of the most challenging activities in Software Engineering scenarios. Moden-Based Testing (MBT) is a feasible strategy to alleviate efforts on automating testing activities. Trough a model that specifies the behavior of the Software Under Testing (SUT), MBT approaches are useful strategies to generate test cases and run them. However, some domains such as, web applications require extra efforts on applying MBT approaches. Due to this, in this study we propose and validate Teasy a Domain Specification Language (DSL) that makes MBT feasible for web application. Through the conduction of a Proof-of-Concept on testing a real-world web application, we noticed Teasy has potential to evolve to effectively support software development environments. Using a real-world application and projects with manually seeded faults, Teasy testing scenarios have detected 78,57% of the functional inconsistencies.

Regression testing of evolving software is a critical constituent of the software development process. Due to resources constraints, test case prioritization is one of the strategies followed in regression testing during which a test case that satisfies predefined objectives the most, as the tester perceives, would be executed the earliest. In this study, all the experiments were performed on three web applications consisting of 65 to 100 pages with lines of code ranging from 5000 to 7000. Various state-of-the-art approaches such as, heuristic approaches, Greedy approaches, and meta heuristic approaches were applied so as to identify the prioritized test sequence which maximizes the value of average percentage of fault detection. Performance of these algorithms was compared using different parameters and it was concluded that the Artificial Bee Colony algorithm performs better than all. Two novel greedy algorithms are also proposed in the study, of which the goal is to smartly manage the state of a tie, where a tie exhibits the condition that all the test cases participating in the tie are of equal significance in achieving the objective. It has also been validated that the performance of these novel proposed algorithm(s) is better than that of traditionally followed greedy approach, most of the time.

Asynchronous Communications

Web application testing is a great challenge due to the management of complex asynchronous communications, the concurrency between the clients-servers, and the heterogeneity of resources employed. It is difficult to ensure that a test case is re-running in the same conditions because it can be executed in undesirable ways according to several environmental factors that are not easy to fine-grain control such as network bottlenecks, memory issues or screen resolution. These environmental factors can cause flakiness, which occurs when the same test case sometimes obtains one test outcome and other times another outcome in the same application due to the execution of environmental factors. The tester usually stops relying on flaky test cases because their outcome varies during the re-executions. To fix and reduce the flakiness it is very important to locate and understand which environmental factors cause the flakiness. This paper is focused on the localization of the root cause of flakiness in web applications based on the characterization of the different environmental factors that are not controlled during testing. The root cause of flakiness is located by means of spectrum-based localization techniques that analyse the test execution under different combinations of the environmental factors that can trigger the flakiness. This technique is evaluated with an educational web platform called FullTeaching. As a result, our technique was able to locate automatically the root cause of flakiness and provide enough information to both understand it and fix it.

Web applications are the most widely used software in the internet. When a web application is developed and deployed in the real environment, It is very severe if any bug found by the attacker or the customer or the owner of the web application. It is the very important to do the proper pre-analysis testing before the release. It is very costly thing if the proper testing of web application is not done at the development location and any bug found at the customer location. For web application testing the existing systems such as DART, Cute and EXE are available. These tools generate test cases by executing the web application on concrete user inputs. These tools are best suitable for testing static web sites and are not suitable for dynamic web applications. The existing systems needs user inputs for generating the test cases. It is most difficult thing for the human being to provide dynamic inputs for all the possible cases. This paper presents algorithms and implementation, and an experimental evaluation that revealed HTML Failures, Execution Failures, Includes in PHP Web applications.

Much work has been done on automating regression testing for applications. But most of them focus on test execution. Little work has been done on automatically determining if a test case passes or fails. This decision is often made by comparing the results of executing test cases on a base version of the application and post-modification version of the application. If the two results match, the test case passes, otherwise fails. However, to the best of our knowledge, there is no regression testing method for automatically deciding pass/fail of dynamic Web applications which use JavaScript or CSS. We propose a method that automatically decides if a dynamic Web application passes a regression test case. The basic idea is to obtain a screenshot each time the GUI of the Web application (i.e. Web page) changes its state, and then compare each corresponding screenshot to see if they match. The evaluation results showed that the accuracy rate of our approach is high and our approach can be considered as fast enough for practical use.

This article presents a cloud-based framework that thwarts the DOM-based XSS vulnerabilities caused due to the injection of advanced HTML5 attack vectors in the HTML5 web applications. Initially, the framework collects the key modules of web application, extracts the suspicious HTML5 strings from the latent injection points and performs the clustering on such strings based on their level of similarity. Further, it detects the injection of malicious HTML5 code in the script nodes of DOM tree by detecting the variation in the HTML5 code embedded in the HTTP response generated. Any variation observed will simply indicate the injection of suspicious script code. The prototype of our framework was developed in Java and installed in the virtual machines of cloud environment on the Google Chrome extension. The experimental evaluation of our framework was performed on the platform of real world HTML5 web applications deployed in the cloud platform.

The design of responsive Web applications is traditionally based on the assumption that they run on a single client at a time. Thanks to CSS3 media queries, developers can declaratively specify how the Web application UI adapts to the capabilities of specific devices. As users own more and more devices and they attempt to use them to run Web applications in parallel, we propose to extend CSS media queries so that they can be used to adapt the UI of liquid Web applications while they are dynamically deployed across multiple devices.In this paper we present our extension of CSS media queries with liquid-related types and features, allowing to detect the number of devices connected, the number of users running the application, or the role played by each device. The liquid media query types and features defined in this paper are designed and suitable for liquid component-based Web architectures, and they enable developers to control the deployment of individual Web components across multiple browsers. Furthermore we show the design of liquid media queries in the Liquid.js for Polymer framework and propose our adaptation algorithms. We describe multiple adaptation policies and discuss the implications of the multi-device adaptation from the perspective of the developers and users of a Web application. Finally we showcase the expressiveness of the liquid media queries to support real-world examples and evaluate the algorithmic complexity of our approach.
