Firstly, a test absolutely does help, even after the fact, as a way to debug. 
It provides a concise definition of the bug, and if the test is kept around, it 
will show whether the bug remains fixed.

But I think the point was that if your specs are comprehensive enough to begin 
with, you will not introduce nearly as many bugs. I'm not arrogant enough to 
say "none at all", but I've also never worked on a project which did Behavior-
Driven Design religiously enough for this to work.
