先引入test启动器

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

在测试类中标注：@RunWith(SpringRunner.class) 指定spring的测试环境；@SpringBootTest(classes = BaseApp.class,webEnvironment= SpringBootTest.WebEnvironment.RANDOM\_PORT) 指定启动类，并加载servlet容器随机创建端口号；

字段上标注 @LocalServerPort 获取随机端口；

注入 RestTemplate，进行测试rest接口；

@before 每个方法执行之前都会调用，运行一个方法执行一次；

@after 方法执行之后，运行一个方法执行一次；

@beforeClass 所有方法执行前会调用一次；

@afterClass 所有方法执行后调用一次；

启动类

package cn.it.oo;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.web.client.RestTemplateBuilder;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.web.client.RestTemplate;
    
    /**
     * @Auther: 
     * @Date: 2019/1/16 10:31
     * @Description:
     */
    
    @SpringBootApplication
    public class BaseApp {
        @Autowired
        private RestTemplateBuilder restTemplateBuilder;
    
        @Bean
         RestTemplate getRestTemplate(){
            return restTemplateBuilder.build();
    }
        public static void main(String[] args) {
            SpringApplication.run(BaseApp.class,args);
        }
    }

接口

package cn.it.oo;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import javax.annotation.Resource;
    import java.util.HashMap;
    import java.util.Map;
    
    /**
     * @Auther: 
     * @Date: 2019/1/16 15:14
     * @Description:
     */
    @RestController
    public class Goods {
        @RequestMapping("/home")
        String home(){
            return "hello word";
        }
    }

测试类

package cn.it.oo;
    
    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.context.embedded.LocalServerPort;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    import org.springframework.web.client.RestTemplate;
    
    /**
     * @Auther: 
     * @Date: 2019/1/16 16:47
     * @Description:
     */
    
    @RunWith(SpringRunner.class)
    @SpringBootTest(classes = BaseApp.class,webEnvironment= SpringBootTest.WebEnvironment.RANDOM_PORT)
    public class GoodsTest {
        @LocalServerPort
        private  int port;
        @Autowired
        private RestTemplate restTemplate;
    
        private  String url;
    
        @Before
        public  void beforeTest(){
            url="http://localhost:"+port;
            System.out.println("setup test base url = "+url);
        }
    
        @Test
        public void testHome(){
            String res = restTemplate.getForObject(url+"/home", String.class);
            System.out.println("invoke testHome res="+res);
        }
    
        @Test
        public void testHome1(){
            String res = restTemplate.getForObject(url+"/home", String.class);
            System.out.println("invoke testHome res###="+res);
        }
    }
