Is code duplication allowed in this instance?

Can you clarify this scenario a bit?

If you are performing black-box testing I don't see why you need to
use the same algorithm in the test code. But maybe your case is
special. On the other hand you can not perform black-box testing if
the output is not known for a given input.
