The Selenium 4 version introduces two new methods, getDomAttribute() and getDomProperty(), which provide more precise ways to retrieve an element's attribute or property values. These methods are recommended for performance and precision, especially when running tests on Sauce Labs, as they reduce the time it takes to execute commands by avoiding the need to send a large blob of JavaScript over the internet. The new methods have different implementations compared to the previous getAttribute() method, which was not accurate in retrieving attribute values. The article provides examples in Java to demonstrate when to use each method, highlighting cases where one returns false and the other returns null, and also showcases scenarios where the results update differently between the two methods.
