The article provides a comprehensive guide on handling multiple browser windows using Selenium and Protractor for automated testing. It emphasizes the importance of managing multiple windows to enhance the user experience and prevent issues during testing. The guide introduces key methods such as getWindowHandle(), getWindowHandles(), and switchTo() for navigating between windows and tabs, explaining how each method uses Global Unique Identifiers (GUID) to identify and switch between different windows. It includes practical demonstrations, such as opening new tabs and performing actions across multiple windows, and offers insights into additional features available in Protractor for browser window management. The article also highlights the flexibility of executing these tests on cloud platforms like LambdaTest's Selenium Grid, which requires minimal configuration changes to connect and run scripts. With a focus on practical application, the guide serves as a valuable resource for automation testers looking to expand their skills in handling complex browser scenarios.
