> I've found that the more I write testable code the better organised my code gets. Automated testing forces you to design maintainable, organised code - because your test suite really won't cope with disorganised code. It can, but it will get out of hand really quickly. Worst case scenario the test suite becomes so tightly bound to the implementation that is becomes a part of it. This forces the test suite to be rewritten in the implementation changes, this is the worst case scenario and must be avoided at all costs.
