SpringBoot整合Junit

5.2 SpringBoot整合Junit

5.2.1 添加Junit的起步依赖

	org.springframework.boot
	spring-boot-starter-test
	test

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
