### Question:
GraphPredicate implements Predicate { @Override public Predicate or(Predicate... predicate) { Preconditions.argumentNotNull(predicate,"predicate::Predicate"); Predicate root = predicate[0]; conditionOp(PredicateOperation.OR, predicate); return root; } GraphPredicate(); private  GraphPredicate(Name name, Object value,
                           PredicateComparison pComparison); Name getName(); Object getValue(); PredicateComparison getpComparison(); PredicateOperation getpOperation(); Predicate getNextPredicate(); @Override Predicate and(Predicate... predicate); @Override Predicate or(Predicate... predicate); @Override Comparison attribute(Name name);  }### Answer:
@Test public void testPredicateOr(){ GraphPredicate graphPredicate1 = new GraphPredicate(); GraphPredicate graphPredicate2 = new GraphPredicate(); Predicate andPredicate = graphPredicate1.or(graphPredicate2); assertEquals(andPredicate, graphPredicate2); }
