DistinctSingleKlvProcessor extends SingleFieldKlvProcessor { @Override public void accept(Visitor visitor) { visitor.visit(this); } protected  DistinctSingleKlvProcessor(String attributeName, String stanagFieldName); @Override void accept(Visitor visitor);  }### Answer:
@Test public void testAccept() { DistinctSingleKlvProcessor distinctKlvProcessor = new DistinctSingleKlvProcessor("a", "b"); KlvProcessor.Visitor visitor = mock(KlvProcessor.Visitor.class); distinctKlvProcessor.accept(visitor); verify(visitor).visit(distinctKlvProcessor); }
