Why is Selenium not able to handle multiple windows or tabs?

When automating a website or an online application, you would encounter situations where several windows within the program appear upon clicking a button. The user is required to take action on each of the opened windows.

Suppose you are facing a situation where Selenium cannot handle multiple windows or tabs. In that case, consider using alternative web drivers such as the ChromeDriver and InternetExplorerDriver that supports multiple windows.

Let’s discuss a few methods to work on all windows at once while exerting control over parent and child windows using Selenium.

• getWindowHandle(): With this method, you get a unique ID of the current window, which will identify it within this driver instance.
• getWindowHandles(): With this method, you get the IDs of all the windows the web driver opens. Its return type is Set .
• switchTo(): Using this method, you can perform switch operations within windows.
