Black-box model-based regression testing of fail-safe behavior in web applications

This paper provides an approach for selective black-box model-based regression testing for web applications, emphasizing testing proper mitigation of external failures in web applications. This approach uses an existing model of web applications, FSMWeb, and extends its test generation capabilities to include selective regression testing of fail-safe behavior. It classifies existing tests as reusable, retestable, and obsolete. The approach reduces the number of tests compared to a full retest between 3% to 81% depending on the type of changes in the example and by over 99% in the case study. Removing reusable requirements reduced test requirements between 49% to 65% in the case study. The approach also uses partial regeneration for new tests wherever possible.

Automated Regression Test Case Generation for Web Application

Testing is one of the most important phases in the development of any product or software. Various types of software testing exist that have to be done to meet the need of the software. Regression testing is one of the crucial phases of testing where testing of a program is done for the original test build along with the modifications. In this article, various studies proposed by the authors have been analysed focusing on test cases generation and their approach toward web application. A detailed study was conducted on Regression Test Case Generation and its approaches toward web application. From our detailed study, we have found that very few approaches and methodologies have been found that provide the real tool for test case generation. There is a need of an automated regression testing tool to generate the regression test cases directly based on user requirements. These test cases have to be generated and implemented by the tool so that the reduction in the overall effort and cost can be achieved. From our study, we have also found that regression testing for web applications was not investigated much, but in today's scenario web applications are an integral part of our daily life and so that needs to be tested for regression testing.

Automation Testing: An Introduction to Selenium

A good tool for testing is the one which has the ability to augment the testing performance and its competences as well as that can be a part of automation. When we chooses to build and host a Web application; automated regression testing becomes a responsibility for accomplishment. As the need of Web applications are growing, with each subsequent release, testing needs to grow tremendously. In this paper we will discuss the introduction to regression testing for Web applications and the Selenium testing framework. Selenium is open source and portable software available for different windows.

An automated tool for regression testing in web applications

Regression testing of web applications is a costly activity as it tends to generate more test cases than the previous stages of software testing. This cost can be reduced significantly by identifying and testing only the modified parts of a web application. This will require locating the changes that have been introduced in the web application from the previous version that was tested. In this paper we have introduced an automated tool for locating the changes in the web application which will thereby aid in effective regression testing of the application. This tool compromise of 3 parts, a) a web crawler that crawls the web application, b) an HTML DOM tree generator that generates the DOM tree for a specified web page, c) an comparator that compares the new DOM tree with a previous version of the DOM tree stored in our system.

How Crawlers Aid Regression Testing in Web Applications: The State of the Art

today's world web applications have increasingly become very popular, and with the same speed they are been upgraded frequently. This poses a big challenge for web application testing. To ensure web application quality, we must perform adequate testing for the new features as well as regression testing the web application in each of iteration. This requires us to systematically identify/locate changes introduced in the new iteration. This paper surveys various tools which identify/locate new changes, which greatly facilitates web application testing in short release cycles. Also we will describe what are web crawler's and show how crawlers can aid in regression testing of web applications.

New test case prioritization strategies for regression testing of web applications

A test case prioritization technique reschedules test cases for regression testing in an order to achieve specific goals like early fault detection. Currently, black box testing of web applications requires manual prioritization of test cases which is very time consuming. We propose a new two level prioritization approach to prioritize test cases for web applications as a whole. Our approach selects modified functionalities in a web application and automatically executes test cases on the basis of the impact of modified functionalities. We suggest several new prioritization strategies for web applications and examine whether these prioritization strategies improve the rate of fault detection for web applications. We propose a new test suite prioritization model for web applications that detects modified functionalities, selects test cases related to those functionalities and reschedules them to detect faults early in test suite execution.

Automated Server-Side Regression Testing for Web Applications

With conventional regression test tools for Web applications, it is difficult to specify the values to be verified that are repeated output inside loop statements. We need to select each of these values displayed in Web pages with the mouse. This paper presents a method that automates regression testing of Web applications on the server side. This method makes it easy to specify values to be verified and enables us to specify them when we develop Web applications. We can directly check the verification results on the Web pages that are shown in the Web browser. If we find a fault, we can even directly modify a part of the server program in the Web browser that corresponds to the currently displayed Web page.

Web Application Tests with Selenium

Web applications tend to continuously evolve and thus need thorough, yet lean and automatic, regression testing. In this installment of Software Technology, Andreas Kornstadt and his colleagues describe automatic regression testing for Web applications that uses the Selenium testing framework. Selenium is portable open source software available for Windows, Linux, and Macintosh. Tests are written as HTML tables or in a number of programming languages and can run directly in most Web browsers. Andreas and his colleagues also provide many useful testing hints for practitioners. We look forward to hearing from both readers and prospective column authors about this column and the technologies we want to know more about.
