Annotation Type VisibleForTesting

@Retention(value=CLASS)
 @Target(value={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.
