# 1、需要导入的依赖 #

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

# 2、创建测试文件夹 #

# 3、打开我们编写好的service类 #

# 在该类里面，ctrl+shift+T组合键，生成对应的单元测试类 #

# 单击OK键，自动生成 #

# 4、修改生成的测试类 #

import com.thread.service.PurchaseService;
    import org.junit.Assert;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.test.context.junit4.SpringRunner;
    
    import static org.junit.jupiter.api.Assertions.*;
    
    @RunWith(SpringRunner.class)
    @SpringBootTest
    public class PurchaseServiceImplTest { 
        @Autowired
        PurchaseService purchaseService = null;
        @Test
        public void purchase() { 
    // Assert.assertEquals(Integer.valueOf(1),purchaseService.purchase(1L,1L,1));
            Assert.assertNotNull(purchaseService.purchase(1L,1L,1));
        }
    }

# 单击左侧这两个按钮，即可执行测试方法 #

# 注意，@Test注解的包别导错了：org.junit.Test #

# 5、测试restful接口 #

@RunWith(SpringRunner.class)
    /*测试restful接口的时候，使用随机端口测试服务*/
    @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT )
    public class RestFulTest { 
    
        /*REST测试模板，Spring Boot自动提供*/
        @Autowired
        private TestRestTemplate restTemplate;
    
        @Test
        public void getUser(){ 
            /*请求当前启动的项目，请注意URI的缩写，没有指定IP和PORT*/
            User user = this.restTemplate.getForObject("/user/{id}", User.class, 1);
            System.out.println("user:"+user.getUserName());
            Assert.assertNotNull(user);
        }
    
    }
