“…The problem of creating and maintaining test suites for web applications has been studied under different points of view in the context of testing and test automation [5,6,12]. Other works deal with the problem of automatically or semi-automatically extract information from structured sources [10,[20][21][22][23][24].…”

Automated test scripts are used with success in many web development projects, so as to automatically verify key functionalities of the web application under test, reveal possible regressions and run a large number of tests in short time. However, the adoption of automated web testing brings advantages but also novel problems, among which the test code fragility problem. During the evolution of the web application, existing test code may easily break and testers have to correct it. In the context of automated DOM-based web testing, one of the major costs for evolving the test code is the manual effort necessary to repair broken web page element locators -lines of source code identifying the web elements (e.g. form fields and buttons) to interact with.In this work, we present ROBULA+, a novel algorithm able to generate robust XPath-based locatorslocators that are likely to work correctly on new releases of the web application. We compared ROBULA+ with several state of the practice/art XPath locator generator tools/algorithms. Results show that XPath locators produced by ROBULA+ are by far the most robust. Indeed, ROBULA+ reduces the locators' fragility on average by 90% w.r.t. absolute locators and by 63% w.r.t. Selenium IDE locators.

“…Some empirical studies compare the robustness of absolute and relative XPath expressions used in wrappers with manually defined relative XPaths. Kowalkiewicz et al found that, on a dataset composed of different versions of a large number of web pages, absolute and relative XPaths were robust, respectively, in 47% and 76% of the cases.…”

“…For example, the location "body/table [1]/tr [1]/td [2]/form" [9] means that the block is the form located in the first row, the second column of the first table from "body". XPath syntax can be used for the value of the target.…”

In mobile environment, because of the handheld devices' capability limitation and diversity, content adaptation becomes an essential technology for web services. In this paper, adaptation for handheld device's web access is studied. For solving the JSP resource-wrapping problem, a document type definition (DTD) is given for device independent page markup language (DIML) [1]. The problem for collecting the properties and the environment context of devices is solved by defining DTM (Device logical traits modeling). Finally we describe the adaptationprocessing algorithm by using DIML and DTM, and solve the problem for adaptation of massive HTML pages of Java-based web servers.

“…Webviews [10] allows users to create customized views of pages they wish to view, using XPaths. Reference [11] studies the robustness of item location in Web pages when different kinds of XPaths are used to point to these locations. Robustness under changes to the Web page is studied for different kinds of XPath expressions such as single-node pointing, alternative predicate expression, and relative addressing expression.…”

The eShopmonitor: A comprehensive data extraction tool for monitoring Web sites

Typical commercial Web sites publish information from multiple back-end data sources; these data sources are also updated very frequently. Given the size of most commercial sites today, it becomes essential to have an automated means of checking for correctness and consistency of data. The eShopmonitor allows users to specify items of interest to be tracked, monitors these items on the Web pages, and reports on any changes observed. Our solution comprises a crawler, a miner, a reporter, and a user component that work together to achieve the above functionality. The miner learns to locate the items of interest on a class of pages based on just one sample supplied by the user, via the user interface (UI) provided. The learning algorithm is based on the XPaths of the Document Object Model (DOM) of the page.
