Design By Contract does not seem to solve the problem, it only makes language translator complain a little earlier, does it?

Yes, but nothing can solve that problem really, since its "user error". I forgot where I heard it, but I have always like the quote: "Complain early and often" when speaking about error handling.

We need to test the code with both correct and incorrect input values in any case.

I agree. My point is that you can efficiently create those tests using this style and not have the overhead of full blown conditional blocks.
