Testing in total isolation is a myth. To be a little softer -- it's really going to depend on the type of class you are testing whether or not it can be rationally tested in isolation. If you haven't lately, you should re-read Lakos's treatment of this subject in Large Scale C++ Software Design. This book is 10 years old, but he breaks down testability in a way I've not seen anyone else do since doing testing became all the rage. Most of the 'test first' stuff I've seem ignores the inherent untestability of some software.
That's been my impression. One of the things I've been trying to figure out wrt the whole testing hoopla is how well it translates to large projects and how it has to be adjusted when things move beyond toy examples. And yes, I probably should go back and reread Lakos. Scott
