My primary reason against Tests for CSS, is that CSS is not about business logic. And the other being that the way CSS works is the last run CSS styling over-rides the previous one. Unit-testing eh? The order of CSS styling that is applied depends on the order of inclusion, correct? Now write anaother test for this? All these thoughts, made me laugh at the idea of Testing the CSS back then. All said, I was still curious to know what was the positive/negative experience of those who tried it.
