无法使用PowerMock模拟构造函数

本文介绍了无法使用PowerMock模拟构造函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在下面的代码中，我无法使用PowerMock模拟构造函数. 我想在下面的语句中打勾.

Here in below code i am not able to Mock Constructor using PowerMock. I want to MOck below statement.

APSPPortletRequest wrappedRequest = new APSPPortletRequest(request);

下面是我的模拟步骤

@PrepareForTest({APSPPortletRequest.class}) @RunWith(PowerMockRunner.class) public class ReminderPortletControllerTest { private PortletRequest requestMock; private APSPPortletRequest apspPortletRequestMock; public void setUp() throws Exception { requestMock = EasyMock.createNiceMock(PortletRequest.class); apspPortletRequestMock = EasyMock.createNiceMock(APSPPortletRequest.class); } @Test public void testExecuteMethod() throws Exception { PowerMock.expectNew(APSPPortletRequest.class, requestMock).andReturn(apspPortletRequestMock).anyTimes(); EasyMock.replay(apspPortletRequestMock, requestMock); PowerMock.replayAll(); } }

请在那方面建议我.

推荐答案

要模拟这一行

APSPPortletRequest wrappedRequest = new APSPPortletRequest(request);

此对象创建调用仅使用一个参数，但是在测试方法中进行模拟时，您要将两个值传递给expectNew方法.

this object creation call takes only one parameter,but while mocking in your test method you are passing two values to expectNew method.

实际上您应该这样做

PowerMock.expectNew(APSPPortletRequest.class, EasyMock.anyObject(requestClass.class)).andReturn(apspPortletRequestMock).anyTimes();

这样做是告诉编译器，只要在类APSPPortletRequest上以请求类的任何对象作为参数调用"new"运算符，就返回一个模拟实例apspPortletRequestMock.

by doing this you are telling compiler to return a mocked instance apspPortletRequestMock whenever 'new' operator is called on class APSPPortletRequest with any object of request class as parameter.

您还缺少一点，您也需要重播所有Easymock对象.即EasyMock.replay(...);也需要存在.

and you are also missing a small point you need to replay all the Easymock objects too.. i.e. EasyMock.replay(...); also needs to be present.

希望这会有所帮助！

祝你好运！
