It's all production

Every now and then, I come across a discussion about whether test code deserves as much care as production code. I understand what is meant (the answer is yes), but I don't accept the premise of the question.

All code is production code. Deployment scripts, tests, database migrations and Java controllers all play a part in delivering value to the users. If a piece of code really has no effect on production, why was it ever written?
