Real life scenario:
Slightly changed requirements from category "eventually" - gives as result quite lot code changes.
An extra problem was that in one production environment it have to work on PHP 4, so application needs downgrading from PHP 5 mainly in XML processing area.
Solution:
Writing more tests for new features.
Gradually code fixing and refactoring.
As a result I have more clean, better working code with new features and potentially new undetected bugs :) .
Savings from using unit and regression testing are almost priceless.
Trying to do some changes like that in PHP production code without automated tests will be really painfull.
