As WebTest is our main test automation tool that we are using since 2004, it is always good to read about it.
Marc Guillemot, lead developer of WebTest and HtmlUnit had a speech about WebTest in the JUG Cologne and has published some future plans of WebTest amongst other things.
Presentation materials can be found in his blog.
Most wanted future option for Aqris would be the integration with Jmeter that would make writing load tests much easier and more functional.
