Junit单元测试时提示：Method should have no parameters

 场景

Junit中运行单元测试时提示：

Method XXX should have no parameters

如图：

代码如下：

package com.ws.test.common;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.ws.sys.entity.SysEnterpriseOrg;
import com.ws.sys.mapper.SysEnterpriseOrgMapper;
import org.junit.Test;

import java.util.ArrayList;
import java.util.List;



public class diguiTest extends ServiceImpl<SysEnterpriseOrgMapper, SysEnterpriseOrg> {

    List<Long> result = new ArrayList<Long>();
    @Test
    public void test(){
        List<Long> canshu = new ArrayList<Long>();
        canshu.add(1l);
        selectChild(canshu);
        for (Long s :result
             ) {
            System.out.print(s);
        }
    }
    @Test
    public void selectChild(List<Long> ids){
        List<Long> temp= new ArrayList<Long>();
        List<SysEnterpriseOrg> sysEnterpriseOrgList = new ArrayList<SysEnterpriseOrg>();
        for (Long id :ids) {
            //查询子级架构
            QueryWrapper<SysEnterpriseOrg> sysEnterpriseOrgChildQueryWrapper = new QueryWrapper<SysEnterpriseOrg>();
            sysEnterpriseOrgChildQueryWrapper.eq("pid",id);
            sysEnterpriseOrgList= this.baseMapper.selectList(sysEnterpriseOrgChildQueryWrapper);
           if(sysEnterpriseOrgList!=null&&sysEnterpriseOrgList.size()!=0){
                for (SysEnterpriseOrg s:sysEnterpriseOrgList) {
                    temp.add(s.getId());
                    result.add(s.getId());
                }
                selectChild(temp);
            }
        }
    }
}

解决

Junit的单元测试@Test不能有返回值和参数。

所以将下面递归函数的@Test去掉即可。

package com.ws.test.common;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.ws.sys.entity.SysEnterpriseOrg;
import com.ws.sys.mapper.SysEnterpriseOrgMapper;
import org.junit.Test;

import java.util.ArrayList;
import java.util.List;



public class diguiTest extends ServiceImpl<SysEnterpriseOrgMapper, SysEnterpriseOrg> {

    List<Long> result = new ArrayList<Long>();
    @Test
    public void test(){
        List<Long> canshu = new ArrayList<Long>();
        canshu.add(1l);
        selectChild(canshu);
        for (Long s :result
             ) {
            System.out.print(s);
        }
    }

    public void selectChild(List<Long> ids){
        List<Long> temp= new ArrayList<Long>();
        List<SysEnterpriseOrg> sysEnterpriseOrgList = new ArrayList<SysEnterpriseOrg>();
        for (Long id :ids) {
            //查询子级架构
            QueryWrapper<SysEnterpriseOrg> sysEnterpriseOrgChildQueryWrapper = new QueryWrapper<SysEnterpriseOrg>();
            sysEnterpriseOrgChildQueryWrapper.eq("pid",id);
            sysEnterpriseOrgList= this.baseMapper.selectList(sysEnterpriseOrgChildQueryWrapper);
            if(sysEnterpriseOrgList!=null&&sysEnterpriseOrgList.size()!=0){
                for (SysEnterpriseOrg s:sysEnterpriseOrgList) {
                    temp.add(s.getId());
                    result.add(s.getId());
                }
                selectChild(temp);
            }
        }
    }
}
