The article explores the use of the Page Object Model (POM) in Selenium C# for improving the scalability and maintenance of test automation scripts amidst frequent UI changes. It highlights the challenges posed by dynamic web locators in automated UI tests and recommends POM as a solution to create a modular structure that reduces code duplication. The tutorial explains how POM, a design pattern embraced by the Selenium community, organizes web page elements into separate classes, thus making code maintenance more manageable and enhancing reusability and readability. It also introduces Page Factory as a tool for initializing web elements and demonstrates the application of POM with practical examples using the NUnit framework and the LambdaTest platform. The article emphasizes the importance of using POM for cross-browser testing, particularly in large web applications, and concludes with a call to leverage cloud-based Selenium Grid for more efficient test coverage.
