springboot 单元测试-各个模块举例

controller单测

 import com.fasterxml.jackson.databind.ObjectMapper; 
import lombok.SneakyThrows;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
import org.mockito.junit.MockitoJUnitRunner;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;import java.util.ArrayList;
import java.util.List;import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;@WebMvcTest(DemoFacade.class)
@RunWith(MockitoJUnitRunner.class)
public class DemoFacadeTest {@InjectMocksprivate DemoFacade demoFacade;@Autowiredprivate MockMvc mockMvc;@Mockprivate DemoQryAPI demoQryAPI; // DemoFacade 里的注入的一个类@Beforepublic void init() {// 开启mockMockitoAnnotations.initMocks(this);// 测试方法执行前,初始化MockMvcmockMvc = MockMvcBuilders.standaloneSetup(demoFacade).build();}@Autowiredprivate ObjectMapper objectMapper;@SneakyThrows@Testpublic void selectAll() {PaginationResult<List<DemoQryResp>> obj2 = new PaginationResult();Mockito.when(demoQryAPI.selectAll(Mockito.any())).thenReturn(obj2);obj2.setCode("000000"); String contentParam = "{}"; //jsonmockMvc .perform(MockMvcRequestBuilders.post("/xx/select").contentType(MediaType.APPLICATION_JSON).content(contentParam)).andExpect(status().isOk()) ;}
}

mapper单测

测试自定义的sql对不对

import com.baomidou.mybatisplus.autoconfigure.MybatisPlusAutoConfiguration;
import org.apache.ibatis.session.SqlSessionFactory;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit4.SpringRunner;import javax.sql.DataSource;import static org.junit.Assert.*;
//需要加载的配置
@SpringBootTest(classes = {DataSourceAutoConfiguration.class
, MybatisPlusAutoConfiguration.class,DataSource.class, SqlSessionFactory.class})
@MapperScan(basePackageClasses = DemoMapper.class)
@RunWith(SpringRunner.class)
@ActiveProfiles("mysql") // application-mysql.yml
public class DemoMapperTest { @Autowiredprivate DemoMapper demoMapper;@Testpublic void flushCheckingDetail() {demoMapper.flushCheckingDetail(); }}

 普通类的单测

@RunWith(MockitoJUnitRunner.class)
public class DemoTest {@InjectMocksDemo demo;/*** 测试*/@Testpublic void cal() {List<Integer> list=new ArrayList<>(); list.add(2);list.add(2);Integer sum  = demo.cal(list);  Assertions.assertThat(sum).isEqualTo(4);  }
}

注意：单测主要是测这个方法行不行，集中在这个最小单元，测试快熟，有利于代码的迭代升级，减少bug
