java - 如何为 Junit 测试模拟 executeNamedQuery(query, params)

Question

@Repository 公共类 DAOImpl 扩展 GenericDaoImpl 实现 SomeDAO {

@Autowired
EntityManager em;

@Override
public List<PropertyURL> getProperties(String env) throws Exception{
    List<String> inParam = new ArrayList<>();
    inParam.add(env);
    Map<String, Object> params = new HashMap<>();
    params.put(ProEnum.ENV.getProperty(), inParam);
    List<PropertyURL> URL = null;
    String query = "PropertyURL.getProperty";
    URL = executeNamedQuery(query, params);
    return URL;
}

我如何模拟 executeNamedQuery(query, params) 调用并返回一些东西 Ex:Mockito.when(entityManagerMock.merge(Mockito.any())).thenReturn(someObject);
