+
+Zombie.js allows you to run Unit or Integration tests without a real web browser. Instead, it uses a simulated browser where it stores the HTML code and runs the JavaScript you may have in your HTML page. This means that an HTML page doesn’t need to be displayed, saving precious time that would otherwise be occupied rendering it.

+Headless Chrome is a way to run the Chrome browser in a headless environment without the full browser UI. One of the benefits of using Headless Chrome (as opposed to testing directly in Node) is that your JavaScript tests will be executed in the same environment as users of your site.

+# HtmlUnit
+
+HtmlUnit is a "GUI-Less browser for Java programs". It models HTML documents and provides an API that allows you to invoke pages, fill out forms, click links, etc... just like you do in your "normal" browser. It has fairly good JavaScript support (which is constantly improving) and is able to work even with quite complex AJAX libraries, simulating Chrome, Firefox or Internet Explorer depending on the configuration used.
+
+HtmlUnit is not a generic unit testing framework. It is specifically a way to simulate a browser for testing purposes and is intended to be used within another testing framework such as JUnit or TestNG.
