## 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);
                }
            }
        }
    }
