Using Sahi for Vaadin GUI testing

Hi there,

I try to use this automate test tool for my Vaadin project: http://sahi.co.in/forums/viewtopic.php?id=205
So far, for some of the components, it works fine.

Is there anyone has experience on this one? Can you share with me or compare it with other Automate test tool such as Selenium or TestBench.

Many thanks,
