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 JUnit 5 is the next generation of JUnit. The goal is to create an up-to-date foundation for developer-side testing on the JVM. This includes focusing on Java 8 and above, as well as enabling many different styles of testing. We ask you – our users – to support us so we can keep up the pace. We will continue our work on JUnit regardless of how many donations we receive. However, your support would enable us to do so with greater focus and not only on weekends or in our spare time. For example, we want to meet regularly and work colocated for a few days in order to get things done faster in face-to-face design and coding sessions. Your donations will help to make that a reality!
