Software Design/Specify interface contracts

< Software Design

This page augments Design by contract article on Wikipedia.

Why

edit

Well-specified interface contracts reduce cases when clients intentionally or unintentionally rely on unspecified behaviour, thus making the client code more robust.

Conversely, when clients don't use unspecified behaviour, maintaining the interface's compatibility doesn't require researching the code of the clients.
