About HtmlUnit is a "GUI-Less browser for Java programs" that models HTML documents and provides an API to interact with web pages, such as invoking pages, filling out forms, and clicking links, similar to a standard web browser. It offers fairly good JavaScript support, which is constantly improving and is capable of handling complex AJAX libraries, simulating browsers like Chrome, Firefox, or Edge depending on the configuration used. Typically used for testing purposes or retrieving information from websites, HtmlUnit is not a generic unit testing framework but is intended to simulate a browser within another testing framework such as JUnit or TestNG. It is utilized as the underlying "browser" by various open source tools like WebDriver, Arquillian Drone, and Serenity BDD, and is employed by many projects for automated web testing, including Apache Shiro, Apache Struts, and Quarkus.	About Selenium WebDriver drives a browser natively, as a real user would, either locally or on remote machines. WebDriver is simple, it is designed as a concise and compact programming interface. Through a simple setup, WebDriver can be used with all major browsers. Automate real user interactions in Firefox, Safari, Edge, Chrome, Internet Explorer and more! Selenium WebDriver refers to both the language bindings and the implementations of the individual browser controlling code. This is commonly referred to as just WebDriver. The W3C is an international community that works to develop Web standards. In June 2018, WebDriver became a W3C recommendation. Major browser vendors (Mozilla, Google, Apple, Microsoft) support WebDriver and work constantly to improve the browsers and browser controlling code, which leads to a more uniform behavior across the different browsers, making your automation scripts more stable.
