Annotation Type Nested
@Target(TYPE) @Retention(RUNTIME) @Documented @API(status=STABLE, since="5.0") public @interface Nested
@Nestedis used to signal that the annotated class is a nested, non-static test class (i.e., an inner class) that can share setup and state with an instance of its enclosing class. The enclosing class may be a top-level test class or another
@Nestedtest class, and nesting can be arbitrarily deep.
