## 5.2 SpringBoot整合Junit ##

**5.2.1 添加Junit的起步依赖**

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-test</artifactId>
    	<scope>test</scope>
    </dependency>

**5.2.2 编写测试类**

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class SpringbootJunitApplicationTests {
    
        @Test
        public void contextLoads() {
            System.out.println("这是一个测试类");
        }
    
    }

**其中，SpringRunner继承自SpringJUnit4ClassRunner，使用哪一个Spring提供的测试测试引擎都可以**

public final class SpringRunner extends SpringJUnit4ClassRunner

**@SpringBootTest的属性指定的是引导类的字节码对象**  
**5.2.3 控制台打印信息**
