Automated Software Testing for CSS

In the world of web development, we have established tools and strategies for automated testing of both server-side code and in-browser JavaScript.

In-browser testing techniques compare rendered HTML or style rules of DOM nodes to predefined references, and hence allow automated regression testing of CSS. With these tools and techniques at hand, what are the next challenges of automated CSS testing?
