In an ideal world, you write test cases which solely rely on externally
visible behavior.  In tla's case, you would create all test input data
from scratch, using tla.  It is hard, often practically impossible to
write a test suite that way, especially if you want to be able to
actually run it. 8-)

I agree that the usual approach is to add a test case which shows the
behavioral difference you want to achieve, and adjust existing test
cases accordingly (if they rely in internal details are normally
considered hidden).
