Junit 5集成测试中的@SpringBootTest具有UnsatisfiedDependencyException

时间：2018-10-06 23:15:34

标签： spring-boot junit5

控制器：

@RestController
public class UserController {
    @Autowired
    public UserService svc;
   ...
}

服务：

@Service
public class UserService {
    @Autowired
    private UserDao dao;
   ...
}

Dao是一个简单的存储库界面。

测试：

@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = {UserController.class, UserService.class, UserDao.class})
public class UserIntegrationTest {
    @Autowired
    private UserController controller;

    @Test
    public void createUserTest() {
        User integration = new User();
        integration.setName("integration");
        integration.setEmail("initial@integration.com");
        integration.setRoles(new ArrayList<String>());

        Response response = controller.addUser(integration.getName(), integration.getEmail(), integration.getRoles());
        Assertions.assertEquals(200, response.getStatus());
    }
}

错误输出：

如果我直接运行主应用程序，一切都很好。但是我无法进行测试。

正如其他线程所说，我已经在@SpringBootTest中添加了所有bean类，但是并不能解决问题。 有人知道原因和解决方案吗？

2 个答案:

答案 0 :(得分：0)

您应该直接使用 @SpringBootTest 或在 @SpringBootTest（classes = {Your-Starter-Application-Class}）中指向您的{your-starter-application-class} < / strong>，删除控制器，服务和dao，因为带注释的SpringBootTest中的类用于加载ApplicationContext，如果未定义显式类，则测试将查找嵌套的 @Configuration 类

@SpringBootTest

或

@SpringBootTest(classes = {Your-Starter-Application-Class})

答案 1 :(得分：0)

仅 @SpringBootTest 应该足以加载ApplicationContext。
同样，对于REST API的集成测试，您应该使用 TestRestTemplate 执行REST API，而不是自动装配Controller。可以在带有@SpringBootTest注释的测试类中自动连接TestRestTemplate的实例。
