1.什么是Mockito？
Mockito是一个模拟测试框架，可以让你用优雅，简洁的接口写出漂亮的单元测试。Mockito可以让单元测试易于可读，产生简洁的校验错误。
使用场景
提前创建测试，TDD（测试驱动开发）
团队可以并行工作
你可以创建一个验证或者演示程序
为无法访问的资源编写测试
Mock可以交给用户
隔离系统
2.代码工程
实验目的
mock controller and service
pom.xml
spring-boot-starter-test 中包含 junit5 和 Mockito 相关jar。无需额外引入。

controller
package com.et.mockito.controller;import com.et.mockito.service.HelloService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;import java.util.Map;@RestControllerpublic class HelloWorldController {@AutowiredHelloService helloService;@RequestMapping("/hello")public Map<String, Object> showHelloWorld(){Map<String, Object> map = new HashMap<>();map.put("msg", helloService.sayhi("hblog"));return map;}}
service
package com.et.mockito.service;public interface HelloService {public String sayhi(String name);}
package com.et.mockito.service;import org.springframework.stereotype.Service;/*** @author liuhaihua* @version 1.0* @ClassName HelloServiceImpl* @Description todo* @date 2024/09/09/ 17:44*/public class HelloServiceImpl implements HelloService{public String sayhi(String name) {return "hi"+name;}}

3.测试
mock controller
public void mockController() throws Exception {// mock servicewhen(helloService.sayhi("hblog")).thenReturn("harries");//mock controllerResultActions perform = this.mockMvc.perform(get("/hello"));log.info(perform.andReturn().getResponse().getContentAsString());//verify responsibleperform.andExpect(status().isOk()).andExpect(MockMvcResultMatchers.content().json("{msg:harries}")); // You don't need to write it in escaped json format}
mock Service
public void mock1() {//Mockito.when(helloService.sayhi(Mockito.anyString())).thenReturn("harries");when(helloService.sayhi("hblog")).thenReturn("harries");String str = helloService.sayhi("hblog");log.info(str);Assert.assertNotNull(str);}public void mock2() {when(helloService.sayhi("exception")).thenThrow(new RuntimeException("mock throw exception"));String str1 = helloService.sayhi("exception");}public void mock3() {helloService.sayhi("hblog");Mockito.verify(helloService, Mockito.times(1)).sayhi(Mockito.eq("hblog")) ;}
