新手请问一下怎样用junit4写下面这段代码的用例呢？

public List getAdminAccessList(int adminId,short adminType){
List adminAccessList2=new ArrayList<>();
if(adminType==1){
List menuList=menuDao.queryMenuByParentId(2);

for(Menu m:menuList){

if(1==m.getMenuType()){
m.setParent(null);
m.setMenus(null);
AdminAccess adminAccess2=new AdminAccess();
adminAccess2.setAccessType(0);
adminAccess2.setMenu(m);
adminAccessList2.add(adminAccess2);
}
}

}else if(adminType==2){
List adminAccessList=adminAccessDao.getAdminAccess(adminId);

for(AdminAccess adminAccess:adminAccessList){
adminAccess.getMenu().setParent(null);
adminAccess.getMenu().setMenus(null);
adminAccessList2.add(adminAccess);
}
}
return adminAccessList2;

}

导入junit4的jar包
在你这个方法上写个注解@Test，ok
