Only if you design your tests that way. Tests are just software. If a change to one part of a software system requires massive changes to another part of that same system; then the system is poorly designed. Indeed, that may be the very definition of poor design.

So if a change to your production code causes large changes to your test code, then one, or the other, or both are poorly designed. You have neglected the design. You have allowed couplings to proliferate.
