Annotation Interface VisibleForTesting

@Retention(CLASS)
@Target({TYPE,METHOD,FIELD,CONSTRUCTOR})
@Documented
public @interface VisibleForTesting

Annotates a program element that exists, or is more widely visible than otherwise necessary, specifically for use in test code. More precisely test code within the hadoop-* modules. Moreover, this gives the implicit scope and stability of:

   InterfaceAudience.Private
   InterfaceStability.Unstable
 

If external modules need to access/override these methods, then they MUST be re-scoped as public/limited private.
