At sprylab technologies we've developed a new open source Java tool
based on Selenium and TestNG. It's called WebInLoop and provides some
really useful features for automated web application testing:
* test result reports with screenshots helping you to find bugs in
your
application much faster
* support for querying databases and mail accounts in order to test
complex web applications and workflows
* email-ready reports, script execution and much more
Another extremly helpful feature is the corresponding Maven plugin,
which makes continuous integration for web applications a snap. Check
