Question

我正在尝试使用JUNIT + MOCKITO开发测试用例并因此而面临问题..

这是我试图测试的方法

    public Response create(Request request)
      throws SQLException, InvalidSecretKeyException, UnsupportedEncodingException, GeneralSecurityException,
      InvalidParametersException, InvalidAuthKeyException, ConstraintViolationExceptions, InvalidKeyHashException, InvalidApplicationKeyException {
    User user = userService.validateAndReturnUserBy(request.headers("AuthKey"));

    ApplicationWrapper applicationWrapper = JsonUtil.deSerialize(request.body(), ApplicationWrapper.class);

    //System.out.println(applicationWrapper.getSecretKey());

    Application application=new Application();
    application.setKey(getApplicationKey(user.getUserName(), applicationWrapper.getType().getName(), applicationWrapper.getName()));
    System.out.println("GEN KEY ::::" + getApplicationKey(user.getUserName(), applicationWrapper.getType().getName(), applicationWrapper.getName()));
    application.setName(applicationWrapper.getName());
    application.setPackageName(applicationWrapper.getPackageName());
    application.setSendOTPInResponse(applicationWrapper.getSendOTPInResponse());
    application.setType(applicationWrapper.getType());

    application.setSignature(applicationWrapper.getSignature());
    application.setCreatedAt(getMysqlTimeStamp());
    application.setCreatedBy(user);
    application.setUpdatedBy(user.getId());
    application.setOtpExpiry(applicationWrapper.getOtpExpiry());
    application.setOtpLength(applicationWrapper.getOtpLength());
    application.setRandomNumber(tempRandomNumber);

    validator.validate(application);
    applicationRepository.create(application);
    System.out.println(applicationWrapper);

    Application thisApp =applicationRepository.getBy(application);
     List<String> secretKeys = applicationWrapper.getSecretKey();
     System.out.println("Application Service ::: \n"+thisApp);
     insertApplicationSecretKeys(secretKeys,thisApp);
    Map<String, String> responseBody = new HashMap<>();
    responseBody.put("application_key", application.getKey());
    responseBody.put("message", "Application created Successfully");

    return new Response("success", responseBody);
}

这是我的Mockito + JUnit测试用例

   @Test
  public void shouldCreate() throws SQLException, ResourceNotFoundException, InvalidSecretKeyException,
          UnsupportedEncodingException, GeneralSecurityException, InvalidAuthKeyException, InvalidParametersException, ConstraintViolationExceptions, InvalidKeyHashException, SendGridException, InvalidApplicationKeyException {

    when(request.headers("AuthKey")).thenReturn("some-auth-key");
    when(userService.validateAndReturnUserBy("some-auth-key")).thenReturn(user);
    when(request.body()).thenReturn(JsonUtil.toJson(make(a(ApplicationWrapperMaker.ApplicationWrapper))));
    when(applicationTypeRepository.getByName("WEB")).thenReturn(make(a(ApplicationTypeMaker.ApplicationType)));
    when(userRepository.getByAuthKey("some-auth-key")).thenReturn(user);

    //doNothing().when(appService).insertApplicationSecretKeys(make(a(ApplicationSecretKeyMaker.ApplicationSecretKey)), make(a(Application)));
    //doThrow(new RuntimeException("App created")).when(appService).insertApplicationSecretKeys(make(a(ApplicationSecretKeyMaker.ApplicationSecretKey)), make(a(Application)));

    Response response = applicationService.create(request);

    assertEquals("success", response.getStatus());
    assertNotNull(response.getBody());
  }

insertApplicationSecretKeys（secretKeys，thisApp）存在问题; 被调用..因为Created应用程序对象只是一个模拟对象，所以此方法返回null，并且NullPointer异常即将到达此行。

this app variable is coming NULL.

请帮忙。

你的方法create做得太多了。

特别是实例化Application对象应该在方法之外完成。提供业务逻辑的其他类的对象创建不应该在使用此依赖项的类中进行。应该应用依赖性反转。

最简单的方法是将Application对象作为参数传递给方法（然后将其重命名为configure）。在这种情况下，您可以通过模拟替换它，您可以在模拟上验证预期的方法调用。

Mockito测试用例不包括内部函数调用
