Spring @MockBean沒有注入黃瓜

Question

我正在實現一個SchedulerService，它使用一個AgentRestClient bean從外部系統獲取一些數據。它看起來是這樣的：

@Service 
public class SchedulerService { 

    @Inject 
    private AgentRestClient agentRestClient; 

    public String updateStatus(String uuid) { 
    String status = agentRestClient.get(uuid); 
    ... 
    } 
    ... 
} 

爲了測試這項服務，我使用的是黃瓜，而在同一時間我試圖嘲弄的AgentRestClient使用Spring Boot的@MockBean標註的行爲，具體如下：

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... 
} 

當我嘗試運行任何黃瓜場景時，agentRestClient從不被模擬/注入。該setUp()方法失敗了NPE：

java.lang.NullPointerException

    at cucumber.api.cli.Main.run(Main.java:36) 
    at cucumber.api.cli.Main.main(Main.java:18) 

爲了得到這一點我也跟着下面的2個資源，但仍沒有運氣得到它的工作：

• https://spring.io/blog/2016/04/15/testing-improvements-in-spring-boot-1-4
• http://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/test/mock/mockito/MockBean.html

罪魁禍首似乎是黃瓜集成到Spring中，因爲當我用普通的JUnit @Test方法，嘲笑按預期工作。

那麼你能告訴我什麼黃瓜或春天配置有我錯過或誤解？

感謝， 波格丹

Answer 1

好了，我發現因爲我用黃瓜運行測試，而不是通過春季啓動運行它們的@MockBean註釋被忽略。 Duh ...

因此，我用替換了@MockBean，然後我手動將該模擬注入我的服務層。

所以現在我的測試是這樣的：

@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... 
} 

正如你看到的，我也去掉了@CucumberOptions(glue=...)註解，現在我一定要通過它雖然亞軍，這對於CLI將是使用--glue選項。

我希望這會有所幫助。

@MockBean不會被忽略，豆被嘲笑，但它不注射，這樣你就可以通過@Inject注入它，這正常工作對我來說：

@Inject 
@MockBean 
private AgentRestClient agentRestClient;
