springboot 单元测试
来源：http://www.51testing.com/
之前开发测试程序功能时，采取的都是通过连接访问来测试程序，常用的方法有：
1、直接通过在浏览器输入网址访问；
2、通过公司搭建的eolinker来进行访问测试；
3、通过编写python脚本来进行测试；
4、通过postman工具来测试。
但这样经常会一测就要测一整块，相对单元测试来说定位问题比较麻烦，单元测试能帮助我们拆分方法，单独测试些关键的代码、功能，是日常开发中必备的技能，同时也是各大公司招技术人员的必要要求之一。但今天看了不少文章，也试了不少，发现即是很简单的东西自己也走了不少弯路，所以觉得很有必要把今天的练习写下来。
1、首先是pom.xml的包
<!-- test依赖,必须添加 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> |

2、下面分别是controller层，service层，jpaRepository层
DemoController.class类
package com.test.demo.controllers; import com.test.demo.domain.entities.Address; import com.test.demo.domain.entities.AddressRepository; import com.test.demo.services.DemoService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import java.util.List; @RestController @RequestMapping("/hello") public class DemoController { @Autowired private DemoService demoService; @Autowired private AddressRepository addressRepository; /** * RequestParam 参数里面的name和value的效果是一样的 * RequestMapping 参数里面就只能是value了， * @param name * @return */ @RequestMapping(value = "/queryaddress") public String demo(@RequestParam(name = "name")String name){ List<Address> addressList = demoService.queryAddress("%"+name+"%"); System.out.println(addressList.toString()); return addressList.toString(); } } |
|---|
DemoService.class类
package com.test.demo.services; import com.test.demo.domain.entities.Address; import com.test.demo.domain.entities.AddressRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; @Service public class DemoService { @Autowired private AddressRepository addressRepository; /** * 根据名称查找地区 * @param name * @return */ public List<Address> queryAddress(String name){ return addressRepository.queryListByName(name); } } |
|---|
AddressRepository.class类
package com.test.demo.domain.entities; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.data.jpa.repository.Query; import java.util.List; public interface AddressRepository extends JpaRepository<Address, Integer>{ /** * 根据地区查找数据 * @param name * @return */ @Query(value = "select * from address where address like ?",nativeQuery = true) List<Address> queryListByName(String name); } |
|---|
3、下面是新建测试类
package com.test.demo.controllers; import com.test.demo.Main; import com.test.demo.domain.entities.Address; import com.test.demo.domain.entities.AddressRepository; import com.test.demo.services.DemoService; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.SpringApplicationConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import java.util.List; @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = Main.class)//扫描启动类 public class DemoTest { @Autowired private AddressRepository addressRepository; @Autowired private DemoController demoController; @Autowired private DemoService demoService; /** * 查找地址 * 访问addressRepository层 */ @Test public void query() { System.out.println("===访问addressRepository层===="); List<Address> lst = addressRepository.queryListByName("%我%"); System.out.println(lst.size()); if (lst.size() > 0) { for (Address ad : lst) { System.out.println(ad.toString()); } } } /** * 查找地址，访问controller层 */ @Test public void queryAddress(){ System.out.println("===访问controller层===="); String str = demoController.demo("%我%"); System.out.println(str); } /** * 查找地址，访问service层 */ @Test public void queryServiceAddress(){ System.out.println("===访问service层===="); List<Address> lst = demoService.queryAddress("%我%"); System.out.println(lst.size()); if (lst.size() > 0) { for (Address ad : lst) { System.out.println(ad.toString()); } } } } |
