Junit 无法使用PowerMock模拟构造函数,junit,powermock,easymock,Junit,Powermock,Easymock,在下面的代码中，我无法使用PowerMock模拟构造函数。 我想嘲弄下面的陈述 APSPPortletRequest wrappedRequest = new APSPPortletRequest(request); @PrepareForTest({APSPPortletRequest.class}) @RunWith(PowerMockRunner.class) public class ReminderPortletControllerTest { private Portlet

在下面的代码中，我无法使用PowerMock模拟构造函数。 我想嘲弄下面的陈述

APSPPortletRequest wrappedRequest = new APSPPortletRequest(request);

@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();
   }
}
下面是我的嘲弄步骤

@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();
   }
}
请就此向我提出建议。

因为你想模仿这句台词

@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();
   }
}

APSPPortletRequest wrappedRequest = new APSPPortletRequest(request);
此对象创建调用只接受一个参数，但在测试方法中模拟时，您将两个值传递给
expectNew
方法

@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();
   }
}
事实上你应该这样做

@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();
   }
}

PowerMock.expectNew(APSPPortletRequest.class, EasyMock.anyObject(requestClass.class)).andReturn(apspPortletRequestMock).anyTimes();
通过这样做，您告诉编译器，只要在类APSPPortletRequest上调用“new”操作符并将request类的任何对象作为参数，就会返回一个模拟实例apspPortletRequestMock

@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();
   }
}
您还缺少一点，即您需要重播所有Easymock对象。。i、 e.
EasyMock.replay（…）也需要存在


@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();
   }
}


希望这有帮助


@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();
   }
}



祝你好运
 如果要模拟以下方法：


@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();
   }
}


EncryptionHelper EncryptionHelper=新的EncryptionHelper（“cep”，true）


@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();
   }
}


您可以通过这种方式使用powerMock来实现


@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();
   }
}


一,。导入类


@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();
   }
}


导入静态org.powermock.api.support.membermodification.MemberMatcher.method


@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();
   }
}


导入静态org.powermock.api.support.membermodification.MemberModifier.stub


@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();
   }
}


二,。在junit测试计算器上方添加注释@RunWith和@PrepareForTest


@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();
   }
}


@RunWith（PowerMockRunner.class）


@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();
   }
}


@PrepareForTest（{EncryptionHelper.class}）


@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();
   }
}


3.嘲笑它


@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();
   }
}


EncryptionHelper encryptionHelperMock=PowerMock.createMock（EncryptionHelper.class）


@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();
   }
}


expectNew（EncryptionHelper.class，isA（String.class），EasyMock.anyBoolean（））.andReturn（encryptionHelperMock）


@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();
   }
}


4.回复


@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();
   }
}


PowerMock.replayAll（encryptionHelperMock）


@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();
   }
}



我按照上述步骤操作，工作正常。
您能提供错误信息，或者提供一些关于具体问题的提示吗

@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();
   }
}
