Questions tagged [htmlunit]

HtmlUnit is a "headless browser". Which means that there is no browser GUI and it does no rendering. Though it has a CSS and JS engine to simulate a real browser. Primary purpose is testing and information extraction.

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.

It is typically used for testing purposes or to retrieve information from web sites.

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.

HtmlUnit is used as the underlying "browser" by different Open Source tools like Canoo WebTest, JWebUnit, Selenium WebDriver, JSFUnit, Celerity, ...

HtmlUnit was originally written by Mike Bowler of Gargoyle Software and is released under the Apache 2 license.
