I first heard about Project White from someone at the Agile 2008 conference last week. I haven’t had a chance to play with it yet, I’m very curious to see how it compares. Since it comes from Thoughtworks, I think it’s going to be good. If it makes testing of modal forms and dialogs easier, I’m already sold.
If anyone out there has already been using Project White successfully, it would be great to hear from you.
