junit4异常No tests found matching解决方法

在我测试UserDaoImpl类最后一个方法时junit出现的异常

java.lang.Exception: No tests found matching [{ExactMatcher:fDisplayName=findTest], {ExactMatcher:fDisplayName=findTest(site.cirno.test.UserDaoTest)], {LeadingIdentifierMatcher:fClassName=site.cirno.test.UserDaoTest,fLeadingIdentifier=findTest]] from org.junit.internal.requests.ClassRequest@45ff54e6

测试类：

package site.cirno.test;

import org.junit.Test;

import site.cirno.dao.UserDao;
import site.cirno.dao.factory.UserDaoFactory;
import site.cirno.pojo.User;

public class UserDaoTest {

    @Test
    public void addTest(){
        User user = new User();
        user.setIsTeacher(1);
        user.setJoinTime(new java.sql.Date(new java.util.Date().getTime()));
        user.setUserAge(21);
        user.setUserEmail("xxx@outlook.com");
        user.setUserName("xx");
        user.setUserPassword("123456");
        user.setUserPhone("1400000000");
        user.setUserPlace("地球");
        user.setUserSex(0);
        UserDao userdao = UserDaoFactory.createUserDaoImplInstance();
        userdao.addUser(user);
    }
    
    @Test
    public void deleteTest(){
        UserDao userdao = UserDaoFactory.createUserDaoImplInstance();
        boolean flag = userdao.deleteUser(1);
        System.out.println(flag);
    }
    
    public void findTest(){
        UserDao userdao = UserDaoFactory.createUserDaoImplInstance();
        User user = userdao.findUserById(4);
        System.out.println(user.getUserAge());
    }
}    

测试前两个方法的时候正常通过，测试最后一个方法时出现异常，在网上查找资料之后发现了改正方法，把测试方法名称改为testFind就可以正常运行
