### Question:
HibernateSystemDefinitionDao extends HibernateDaoSupport implements
        SystemDefinitionDao { public SystemDefinition getSystemDefinition(String key) { LOG.debug("get SystemDefinition(key = \"" + key + "\")"); SystemDefinition systemDefinition = (SystemDefinition) getHibernateTemplate().get( SystemDefinition.class, key); LOG.debug("get SystemDefinition(key = \"" + key + "\") = " + systemDefinition); return systemDefinition; }  SystemDefinition getSystemDefinition(String key); @SuppressWarnings("unchecked") SystemDefinition getSystemDefinition(String organizationId,
            String systemId);  }### Answer:
@Test public void testReadSucceeds() throws Exception { SystemDefinition systemA0 = dao.getSystemDefinition("00000000", "00000000"); assertNotNull(systemA0); assertTrue(systemA0.isValid()); assertEquals("00000000", systemA0.getId()); assertEquals("System A0", systemA0.getName()); assertEquals(true, systemA0.isStandard()); assertEquals(1, systemA0.getServices().size()); assertEquals("00000000", systemA0.getOrganization().getId()); ServiceDefinition serviceA0_0 = systemA0.getServiceDefinition("00000000"); assertNotNull(serviceA0_0); assertTrue(serviceA0_0.isValid()); assertEquals("00000000", serviceA0_0.getId()); assertEquals("Service A0-0", serviceA0_0.getName()); assertEquals("M1", serviceA0_0.getRequestMessageTypeId()); assertEquals("M2", serviceA0_0.getResponseMessageTypeId()); assertNull(serviceA0_0.getServiceProviderBeanId()); assertEquals(systemA0, serviceA0_0.getSystem()); }
@Test public void testReadFails() throws Exception { SystemDefinition system = dao.getSystemDefinition("00000000", "00000003"); assertNull(system); }
