• 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.

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.

• TestMaker 6 is the easier way to surface performance bottlenecks and functional issues in Web, Rich Internet Applications (RIA, using Ajax, Flex, Flash,) Service Oriented Architecture (SOA,) and Business Process Management (BPM) applications. TestMaker 6 rapidly puts the PushToTest Methodology into your hands for a test tool that installs on your desktop, runs tests in grid and cloud environments, and pinpoints root causes and offers mitigation. Imagine one open source test tool that repurposes a single test script to be a functional test (smoke tests, regression tests,) load and performance test (scalability tests, stress tests,) and production monitors. That test script is a Selenium test, Sahi test, soapUI test suite, and unit test written in Java, Ruby, Python, and PHP. This is TestMaker 6
