The short question: How do you follow Test-Driven Development on a project that spans multiple languages?

Specifically, I'm writing a web application that uses JavaScript and PHP, and I want to follow the TDD principles, but I'm not sure how to integrate them. Do I run separate test suites for the JS and PHP sections, and use mocks in the JS suite to emulate server responses? Is there a technique for unit testing both components in one run?

This is my first experience using Test-Driven Development, so any advice you can share on how to make it less daunting would be great. The reason I chose it is that as soon as I finished a prototype, the requirements changed, forcing me to change my design. I figured if I'm starting over, I'd like to write more extensible code with built-in regression testing from the start.

UPDATE

I'm writing my PHP tests in SimpleTest and my JavaScript tests in JsTestDriver. I'm used to object-oriented paradigms, so I've got a few classes in PHP, and I'm doing the something similar in JavaScript using prototypal inheritance. I've also started reading this book about TDD in Python and this one about TDD in JavaScript, but from all that I've seen, these don't describe testing an application in full (outside of using something like Selenium or another web driver to perform front-end acceptance testing. Is TDD just not cut out for full-stack developers?

Thanks!
