We can use this unique id to differentiate a window and switch control among multiple windows. WebDriver will be still controlling the old window and any operations that we perform using Selenium script will be forwarded to this old window. For example, opening a link in new window does not transfer control of WebDriver to new window.
This unique id is known as window handles.Īlso note that WebDriver object always controls only one window at a time in the current session.
Python Selenium WebDriver assigns an id to each window as soon as the WebDriver object is instantiated or new window is opened using a WebDriver object. Python Selenium provides option to handle multiple windows using ‘window_handles’. Those are may be advertisements or kind of information showing on popup windows such as terms & conditions, privacy policy or kind of web page itself where user has to enter information. There are many cases where handling multiple windows while working with a web application is required, either application navigates to or opens multiple windows and user has to perform operations in this new window.
