Selenium WebDriver mimics the actions of a real user when interacting with web browsers, whether on local machines or through remote servers. It provides an easy-to-use programming interface that emphasizes efficiency. With very little setup, WebDriver can effectively operate on all major web browsers. This tool allows you to automate processes in widely used browsers such as Firefox, Safari, Edge, Chrome, Internet Explorer, and beyond! The term Selenium WebDriver refers to both the language bindings and the various implementations that enable browser manipulation, and it is often simply referred to as WebDriver. The World Wide Web Consortium (W3C) is an international organization dedicated to creating web standards. In June 2018, WebDriver was formally adopted as a W3C recommendation. Major browser developers like Mozilla, Google, Apple, and Microsoft are committed to supporting WebDriver, continuously improving both their browsers and the associated control code, leading to more uniform functionality across platforms. This uniformity enhances the dependability of your automation scripts, resulting in a more efficient testing process. Consequently, developers can expect their automated tests to yield consistent results across different environments.
