Web functional testing tools?

Hi folks, Just setting out on a major new project, and this time I want to set up a comprehensive regression testing from the start: I've learned the hard way that manual testing is not the way to go! But looking at open-source web application frameworks, most of them are very Java specific, or at least require Java to write the tests. What do people recommend for the functional testing of PHP data-driven apps? (By functional testing I mean testing the application as a whole, as opposed to unit testing.) ------------------ Geoff Caplan Vario Software Ltd (+44) 121-515 1154
