Modern web applications are characterized by ultra-rapid development cycles, and web testers tend to pay scant attention to the quality of their automated end-to-end test suites. Indeed, these quickly become hard to maintain, as the application under test evolves. As a result, end-to-end automated test suites are abandoned, despite their great potential for catching regressions. The use of the Page Object pattern has proven to be very effective in end-to-end web testing. Page objects are façade classes abstracting the internals of web pages into high-level business functions that can be invoked by the test cases. By decoupling test code from web page details, web test cases are more readable and maintainable. However, the manual development of such page objects requires substantial coding effort, which is paid off only later, during software evolution. In this paper, we describe a novel approach for the automatic generation of page objects for web applications. Our approach is implemented in the tool Apogen, which automatically derives a testing model by reverse engineering the target web application. It combines clustering and static analysis to identify meaningful page abstractions that are automatically turned into Java page objects for Selenium WebDriver. Our evaluation on an open-source web application shows that our approach is highly promising: Automatically generated page object methods cover most of the application functionalities and result in readable and meaningful code, which can be very useful to support the creation of more maintainable web test suites.
