you shouldn't change your code specifically for testing

I don't quite agree

my personal preference: change all private attributes to protected ones; then derive a class that simply adds the test code and can access everything; you probably would keep the test class in a separate assembly which you do not distribute.

Dead code is potentially a bug waiting to happen IMHO

it may be worth making a few modifications for testing
