为什么80%的码农都做不了架构师？>>> 
一、单元测试service层
1、首先引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
2、编写service层代码
@Service
public class PracticeService {
public String aaa() {
return "aaa";
}
}
3、编写单元测试代码
@RunWith(SpringRunner.class)
@SpringBootTest
public class PracticeControllerTest {
@Autowired
private PracticeService practiceService;
@Test
public void test() {
String aaa = practiceService.aaa();
System.out.println(aaa);
}
}
注意：SpringBootTest是启动类，默认会自动查找不需要配置，也可以配置。类似@SpringBootTest(classes = SpringbootApplication.class)
二、单元测试控制器
