I've been wondering for a while which presentation
testing framework to use. I know that HtmlUnit simulates a browser and is merciless on bugs that other explorers simply ignore.
I also know that Selenium uses real explorers and through them tests the page. The question is which one should I choose, since some things can't be automatically tested like how a page looks.
However for the things that can be automatically tested, does it really matter which framework I use. In which case does choosing one over the other makes a real impact?
