One major exception to this, is that the people who write the code 
should report to the testers any algorithmic breakpoints that are not 
implied by the specifications. For instance, the size of the data being 
processed my affect which method is used to reach the goal. The test 
suite needs to make sure it exercises every case. Testing likely would 
test the smallest and largest, but if there is distinct middle case, it 
might be missed, and tests near the break points might be called for too.
