我正在实现一个SchedulerService
,它使用AgentRestClient
bean从外部系统获取一些数据。它看起来像这样:
@Service
public class SchedulerService {
@Inject
private AgentRestClient agentRestClient;
public String updateStatus(String uuid) {
String status = agentRestClient.get(uuid);
...
}
...
}
为了测试这项服务,我正在使用Cucumber,同时我正在尝试使用Spring Boot的AgentRestClient
注释来模拟@MockBean
的行为,如下所示:
import cucumber.api.CucumberOptions;
import cucumber.api.java.Before;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest(classes = CentralApp.class)
@CucumberOptions(glue = {"com.company.project.cucumber.stepdefs", "cucumber.api.spring"})
public class RefreshActiveJobsStepDefs {
@MockBean
private AgentRestClient agentRestClient;
@Inject
private SchedulerService schedulerService;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
given(agentRestClient.get(anyString())).willReturn("FINISHED");//agentRestClient is always null here
}
//Skipping the actual Given-When-Then Cucumber steps...
}
当我尝试运行任何Cucumber场景时,agentRestClient
永远不会被模拟/注入。 setUp()
方法因NPE而失败:

为了达到这一点,我遵循了以下两个资源,但仍然没有运气得到它的运气:
罪魁祸首似乎是Cucumber与Spring的集成,因为当我使用普通的JUnit @Test
方法尝试相同的方法时,模拟按预期工作。
那么请你告诉我黄色或春天配置我错过或误解了什么?

@MockBean不被忽略,bean被嘲笑但是它没有被注入,所以你可以通过@inject注入它,这对我来说很好用:
@Inject
@MockBean
private AgentRestClient agentRestClient;

好的,所以我发现@MockBean
注释被忽略了,因为我用Cucumber运行测试而不是通过Spring Boot运行它们。咄...
所以我用@MockBean
替换@Mock
,然后我手动将该模拟注入我的服务层。
所以现在我的测试看起来像这样:
@SpringBootTest(classes = CentralApp.class)
@ContextConfiguration
public class RefreshActiveJobsStepDefs {
@Inject
private SchedulerService schedulerService;
@Mock
private AgentRestClient agentRestClient;
@Before
public void setup() throws Exception {
MockitoAnnotations.initMocks(this);
given(agentRestClient.get(anyString())).willReturn("FINISHED");
schedulerService.setAgentRestClient(agentRestClient);
}
//Skipping the actual Given-When-Then Cucumber steps...
}
正如您所看到的,我还删除了@CucumberOptions(glue=...)
注释,现在我确保通过运行器传递它,对于CLI,它将使用--glue
选项。
我希望这会有所帮助。

@ 3wj的方法适合我。 在我的例子中,bean可选地注入控制器。看起来在这种情况下,@ MockBean将无法正常工作,我猜其原因是bean没有被硬引用。添加一个额外的注释@Autowired以使bean被硬引用,然后Spring将初始化bean。
@RestController
public class MyController {
public MyController(@Autowired(required = false) IMyService myService) {
this.myService = myService;
}
@GetMapping("/the/path")
public ResponseEntity<String> getData() {
if(this.myService==null){
//Throw service unavaillable exception
}
String data = this.myService.getData();
return new ResponseEntity<>(data, HttpStatus.OK);
}
}
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class MyControllerIT {
@Value("${local.server.port}")
private int port;
private RestTemplate restTemplate;
@Autowired
@MockBean
private IMyService myService
@Test
public void testQuery() throws Exception {
// restTemplate to call rest API....
}
}
