Repairing Selenium Test Cases: An Industrial Case Study about Web Page Element Localization

This poster presents an industrial case study about test automation and test suite maintenance in the context of Web applications. The Web application under test is a Learning Content Management System (eXact learning LCMS). We analysed the costs associated with the realignment of four equivalent Selenium WebDriver test suites, implemented using the page object pattern and different methods to locate web page elements, to a subsequent release of eXact learning LCMS. In our study, the two ID-based test suites required significantly less maintenance effort than the XPath-based ones.
