如何使用Mockito模拟外部方法调用

问题描述

paymentBusinessService类在BusinessService类依赖项注入中可用.应用程序sc = Applicaition.applicationValidation(this.deal);应该是
应用程序sc = BusinessService.applicationValidation(this.deal);

paymentBusinessService class is avaiable in BusinessService class dependency injection. The Application sc = Applicaition.applicationValidation(this.deal); suppose to be
Application sc = BusinessService.applicationValidation(this.deal);

package com.core.business.service.dp.fulfillment;
import com.core.business.service.dp.payment.PaymentBusinessService;

public class BusinessServiceImpl implements BusinessService { // Actual Impl Class

private PaymentBusinessService paymentBusinessService = PluginSystem.INSTANCE.getPluginInjector().getInstance(PaymentBusinessService.class);

@Transactional( rollbackOn = Throwable.class)
public Application  applicationValidation (final Deal deal) throws BasePersistenceException {
    Application application = (Application) ApplicationDTOFactory.eINSTANCE.createApplication();
    //External Call we want to Mock
    String report = paymentBusinessService.checkForCreditCardReport(deal.getId());
    if (report != null) {
        application.settingSomething(true);
    }
    return application;
}

}

@Test(enabled = true)// Test Class
public void testReCalculatePrepaids() throws Exception {
PaymentBusinessService paymentBusinessService = mock(PaymentBusinessService.class);
//Mocking External Call
when(paymentBusinessService.checkForCreditCardReport(this.deal.getId())).thenReturn(new String("Decline by only Me"));
String report = paymentBusinessService.checkForCreditCardReport(this.deal.getId());
//Calling Impl Class whose one external call is mocked
Application sc = BusinessService.applicationValidation(this.deal);

}

推荐答案

感谢Aurand给了我将模拟对象注入应用程序类的想法.使用@InjectMock可以正常工作.

Thanks Aurand for giving me the idea of injecting mock object into application class. Using @InjectMock works fine.

@MOCK
PaymentBusinessService paymentBusinessService;

@InjectMock
Application application = PluginSystem.INSTANCE.getPluginInjector().getInstance(Application.class);
@Test(enabled = true)// Test Class
public void testReCalculatePrepaids() throws Exception {
//Mocking External Call
when(paymentBusinessService.checkForCreditCardReport(this.deal.getId())).thenReturn(new       String("Decline by only Me"));
String report = paymentBusinessService.checkForCreditCardReport(this.deal.getId());
//Calling Impl Class whose one external call is mocked
Application sc = BusinessService.applicationValidation(this.deal);
