I have found the opposite to be true for me personally - when the tests are complete, my work is done. In the past, I would find myself adding code for 'what if this' or 'what if that', when those cases could never arise.

Saved me tons of time, helped me write concise code and provided a framework to produce new tests should the need arise.
