用test方法测试serviceImpl层时空指针异常

利用test方法测试，出现空指针异常，而且swagger文档显示no response from server

public List<Test> queryProjectOrg(Integer userId) {
      String role = projectInfoDao.queryRoleByUser(userId);
      List<Test> list = new ArrayList<Test>();
      if ("ALL".equals(role)){
            list = projectInfoDao.findAllOrg();
      }else {
            list = projectInfoDao.queryOrg(userId);
      }
      return list;
    }List<Test> findAllOrg();
    List<Test> queryOrg(@Param("userId")Integer userId);

    String queryRoleByUser(@Param("userId") Integer userId);

List<Test> findAllOrg();
    List<Test> queryOrg(@Param("userId")Integer userId);

    String queryRoleByUser(@Param("userId") Integer userId);
}运行结果及报错内容
