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 TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionalities that make it more powerful and easier to use, such as annotations, or the possibility to run your tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc.). You can test that your code is multithread safe, there is flexible test configuration, support for data-driven testing (with @DataProvider), support for parameters, powerful execution model (no more TestSuite). There is a supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, etc.), it also embeds BeanShell for further flexibility, and there is default JDK functions for runtime and logging (no dependencies), and dependent methods for application server testing. TestNG is designed to cover all categories of tests, unit, functional, end-to-end, integration, etc.
