SpringBoot中如何实现一个项目测试类

package soundsystem;

import static org.junit.Assert.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=CDPlayerConfig.class)
public class CDPlayerTest {

 @Autowired
 private CompactDisc cd;

 @Test
 public void cdShouldNotBeNull() {
  assertNotNull(cd);
 }

}

package com.baizhi.cmfz;


import com.baizhi.cmfz.dao.BannerDao;
import com.baizhi.cmfz.entiy.Banner;
import com.baizhi.cmfz.service.BannerService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.Date;
import java.util.List;
import java.util.Map;

@RunWith(SpringRunner.class)
@SpringBootTest
public class BannerTest {


  @Autowired
  private BannerDao dao;
  @Autowired
  private BannerService service;


  @Test
  public void test1(){
    List<Banner> list = dao.selectAllBanner(1,10,null);
    for (Banner banner : list) {
      System.out.println(banner);
    }
  }

}
