Complexity Control

Why this rule exists

Speculative abstraction is a tax on every future reader. An IFoo with one implementation and no test double doubles the navigation cost without adding flexibility.

Code example

+ public interface IFoo { void Bar(); }
+ public class Foo : IFoo { public void Bar() { ... } }
+ // IFoo has exactly one implementation and no tests use it

+ public class Foo { public void Bar() { ... } }
+ // Extract IFoo when the second implementation or test double appears.
