The article includes detailed steps for setting up a JavaScript testing environment, creating and organizing page objects, writing test cases, and running them locally as well as on a cloud-based Selenium Grid like LambdaTest. Emphasizing the ease of managing large-scale applications with POM, it also highlights the advantages of running tests on a cloud platform to access a wide range of browsers and devices. The article aims to equip testers, especially those new to Selenium JavaScript, with the knowledge to implement effective and scalable test automation practices.
