運行集成測試時未能加載ApplicationContext

Question

我試圖運行mvn integration-test階段，並且在執行集成測試（單元測試得到正確執行）時出現Failed to load ApplicationContext錯誤。我正在使用SpringJUnit4ClassRunner類運行我的測試。

這是一個完整的堆棧跟蹤：

另外，我使用的原型，你可以看到註釋Configuration類here。我究竟做錯了什麼？

這是我的測試類：

@RunWith(SpringJUnit4ClassRunner.class) 
@Transactional 
public class PatientServiceIT { 

    private static final String EMAIL = "account@test.com"; 
    private static final String NAME = "test"; 
    private static final String SURNAMES = "account"; 
    private static final String PASSWORD = "testaccount"; 
    private static final String POSTAL_CODE = "15002"; 
    private static final String MOBILE_NUMBER = "694749217"; 

    @Autowired 
    private AccountRepository accountRepository; 

    @Autowired 
    private PatientRepository patientRepository; 

    @Autowired 
    private PatientService patientService; 

    private PatientDetails createPatientDetails() { 
     return new PatientDetails(EMAIL, PASSWORD, NAME, SURNAMES, MOBILE_NUMBER, POSTAL_CODE); 
    } 

    private Account createPatient() { 
     Account patientAccount = new Account(EMAIL, PASSWORD, NAME, SURNAMES, Role.ROLE_DENTIST); 
     Patient patient = new Patient(POSTAL_CODE, MOBILE_NUMBER); 
     patientAccount.setPatient(patient); 
     return patientAccount; 
    } 

    @Test 
    public void savePatient() { 
     // call 
     Patient patient = patientService.save(createPatientDetails()); 

     // assert 
     assertEquals(patient.getAccount(), createPatient()); 
    } 

} 

PS：我起訴Maven的故障安全爲integration-test目標和神火POR的test目標。

您在測試中缺少@ContextConfiguration(classes = ...)批註環境的定義。由於classes您可能會定義單個配置或您的整個生產應用程序上下文（包括所有其他）。聲明你需要的配置類的好處是整個測試的引導速度更快。

注意：Spring測試會緩存指定的應用程序上下文。如果必須在整個配置中運行9/10測試，則會比聲明一組新的上下文配置需要更少的時間來使用整個配置。但是您應該爲您的集成測試獲得小的配置佔用空間，以便您可以專注於正在工作的域切片，而無需處理或維護其他上下文配置。

通常測試運行SpringJUnit4ClassRunner希望有一個應用程序上下文運行。 延伸閱讀：Link to the spring docs
