Re: [boost] How do you test complex transformations?

I more often verify a couple test-cases by hand and encode those, paying special attention to boundary conditions, etc. Some situations are complex enough that they warrant test hooks to verify intermediate results. And, yes, I leave the hooks in. E.g., "if (test) test->VerifyIntermdiateX(y,z);" Make sure the test-hook pointer is 0 for production.
