### Question:
DatacenterDAO extends DefaultDAOBase<Integer, Datacenter> { public boolean existsAnyOtherWithName(final Datacenter datacenter, final String name) { assert datacenter != null; assert isManaged(datacenter); assert !StringUtils.isEmpty(name); return this.existsAnyOtherByCriterions(datacenter, equalName(name)); } DatacenterDAO();  DatacenterDAO(final EntityManager entityManager); boolean existsAnyWithName(final String name); boolean existsAnyOtherWithName(final Datacenter datacenter, final String name); DefaultEntityCurrentUsed getCurrentResourcesAllocated(final int datacenterId,
        final int enterpriseId); List<Enterprise> findEnterprisesByDatacenters(final Datacenter datacenter,
        final Integer firstElem, final Integer numElem, final Boolean network); static final String BY_ENT_WITH_NETWORK; static final String BY_ENT; }### Answer:
@Test public void test_existsAnyOtherWithName() { Datacenter datacenter = createUniqueEntity(); datacenter.setName("A name"); Datacenter datacenter2 = createUniqueEntity(); datacenter2.setName("Name 2"); ds().persistAll(datacenter, datacenter2); DatacenterDAO dao = createDaoForRollbackTransaction(); datacenter = dao.findById(datacenter.getId()); Assert.assertFalse(dao.existsAnyOtherWithName(datacenter, "INEXISTENT_NAME")); Assert.assertFalse(dao.existsAnyOtherWithName(datacenter, "A name")); Assert.assertTrue(dao.existsAnyOtherWithName(datacenter, "Name 2")); }
