### Question:
NullaryOr extends BaseNullaryPredicateList { public boolean test() { for (NullaryPredicate p : getNullaryPredicateList()) { if (p.test()) { return true; } } return false; } NullaryOr();  NullaryOr(Iterable<NullaryPredicate> predicates);  NullaryOr(NullaryPredicate... predicates); NullaryOr or(NullaryPredicate p); boolean test(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testConstructors() { NullaryOr or = new NullaryOr(Constant.FALSE); assertEquals(Boolean.FALSE, or.test()); NullaryOr or2 = new NullaryOr((Iterable<NullaryPredicate>)Arrays.asList((NullaryPredicate)Constant.truePredicate())); assertEquals(Boolean.TRUE, or2.test()); NullaryOr or3 = new NullaryOr((NullaryPredicate)null); assertEquals(Boolean.FALSE, or3.test()); NullaryOr or4 = new NullaryOr((Iterable<NullaryPredicate>)null); assertEquals(Boolean.FALSE, or4.test()); }
