Yes, but those tests are completely, and always will be, totally
independent of the implementation - the code can change, the language
the system is developed in could change, heck even the platform could
change, but the Acceptance tests remain UNCHANGED and still passing.

Acceptance tests have nothing to do with TDD. Acceptance tests are not
for developers to test their code with, they are to test the system when
it is running.
