Now they talk about specific meaning that a program doesn't change its behavior under a refactoring, in the sense that all the tests of a test suite work as before. It's possible to formalize this notion by providing preconditions and postconditions under which a refactoring is applicable. This in turn allows you to have automatic or semi-automatic tool support. So, for example, you can move a method down an inheritance hierarchy if all call sites call it through a respective subclass anyway (that's the precondition). There are some limitations when your language supports reflective calls, but in general this seems to work quite well. As far as I can tell, this specific notion of "refactoring" is Pascal -- You must Sign in before you can post messages.
