### Question:
EOModelHelper { public Map queryPListMap(String entityName, String queryName) { Map queryPlist = (Map) entityQueryIndex.get(entityName); if (queryPlist == null || queryPlist.isEmpty()) { return null; } return (Map) queryPlist.get(queryName); } EOModelHelper(URL modelUrl); String javaTypeForEOModelerType(String valueClassName, String valueType); DataMap getDataMap(); URL getModelUrl(); Iterator modelNames(); List modelNamesAsList(); Map getPrototypeAttributeMapFor(String aPrototypeAttributeName); Map entityPListMap(String entityName); Iterator queryNames(String entityName); Map queryPListMap(String entityName, String queryName); String entityClass(String entityName, boolean getClientClass);  }### Answer:
@Test public void testQueryPListMap() throws Exception { assertNull(helper.queryPListMap("Artist", "AAA")); assertNull(helper.queryPListMap("ExhibitType", "AAA")); Map query = helper.queryPListMap("ExhibitType", "FetchAll"); assertNotNull(query); assertFalse(query.isEmpty()); }
