概述
@SpringBootTest注解是SpringBoot自1.4.0版本开始引入的一个用于测试的注解。基本用法如下:
1. 添加Maven依赖

2. 编写启动入口类

@SpringBootApplication
public class StartUpApplication {
public static void main(String[] args) {
SpringApplication.run(StartUpApplication. class , args);
}
}
|
3. 编写Controller类

@RestController
public class HelloController {
@RequestMapping ( "/" )
public String index() {
return "Hello Spring Boot,Index!" ;
}
@RequestMapping (value = "/test" , method = RequestMethod.GET)
public String test() {
return "Spring Boot Test Demo!" ;
}
}
|
4. 编写测试类

@RunWith (SpringRunner. class )
@SpringBootTest (classes = StartUpApplication. class , webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class HelloControllerTest {
/**
* @LocalServerPort 提供了 @Value("${local.server.port}") 的代替
*/
@LocalServerPort
private int port;
private URL base;
@Autowired
private TestRestTemplate restTemplate;
@Before
public void setUp() throws Exception {
String url = String.format( "http://localhost:%d/" , port);
System.out.println(String.format( "port is : [%d]" , port));
this .base = new URL(url);
}
/**
* 向"/test"地址发送请求,并打印返回结果
* @throws Exception
*/
@Test
public void test1() throws Exception {
ResponseEntity<String> response = this .restTemplate.getForEntity(
this .base.toString() + "/test" , String. class , "" );
System.out.println(String.format( "测试结果为:%s" , response.getBody()));
}

其中,classes属性指定启动类,SpringBootTest.WebEnvironment.RANDOM_PORT经常和测试类中@LocalServerPort一起在注入属性时使用。会随机生成一个端口号。
总结
我们发现,随着Spring boot 版本的提升,单元测试变得更简单了。
