Java Junit模拟私有方法

我需要模拟私有方法，并且应该返回true。在ServiceImpl-execute（）中，我的请求将转到else{}，它将调用“eventRequest（）”。 它是一个私有布尔eventRequest（），因此每当evenRequest（）调用时，我都应该返回true。有人能帮我吗

ServiceImplTest.java

@RunWith(PowerMockRunner.class)
@PrepareForTest({ServiceImpl.class})
public class ServiceImplTest {

    @Test
    public void testExecute() {
        Response response = serviceImpl.execute(request);
        Assert.assertNotNull(pushResponse);
        Assert.assertEquals(true, pushResponse.isIsSuccess());
    }
}

public class ServiceImpl {
    public Response execute(Request request) {
        Response response = null;
                boolean isSuccess;
                if (returnMockResponse(request, notifyRqst)) {
                    isSuccess = true;
                } else {
                    isSuccess = eventRequest(notifyXmlRqst);
                }
        response = ResponseBuilder.createResponse(isSuccess);
        return response;
    }

    // Need to mock below private method and should return true.
    private boolean eventRequest(String request) throws Exception {
        return eventNotifyResponse.isIsSuccess();
    }
}

public class ResponseBuilder {
    public Response createResponse(boolean result) {
            Response response = new Response();
            response.setIsSuccess(result);
            return response;
    }    
}

ServiceImpl.java

@RunWith(PowerMockRunner.class)
@PrepareForTest({ServiceImpl.class})
public class ServiceImplTest {

    @Test
    public void testExecute() {
        Response response = serviceImpl.execute(request);
        Assert.assertNotNull(pushResponse);
        Assert.assertEquals(true, pushResponse.isIsSuccess());
    }
}

public class ServiceImpl {
    public Response execute(Request request) {
        Response response = null;
                boolean isSuccess;
                if (returnMockResponse(request, notifyRqst)) {
                    isSuccess = true;
                } else {
                    isSuccess = eventRequest(notifyXmlRqst);
                }
        response = ResponseBuilder.createResponse(isSuccess);
        return response;
    }

    // Need to mock below private method and should return true.
    private boolean eventRequest(String request) throws Exception {
        return eventNotifyResponse.isIsSuccess();
    }
}

public class ResponseBuilder {
    public Response createResponse(boolean result) {
            Response response = new Response();
            response.setIsSuccess(result);
            return response;
    }    
}

ResponseBuilder.java

@RunWith(PowerMockRunner.class)
@PrepareForTest({ServiceImpl.class})
public class ServiceImplTest {

    @Test
    public void testExecute() {
        Response response = serviceImpl.execute(request);
        Assert.assertNotNull(pushResponse);
        Assert.assertEquals(true, pushResponse.isIsSuccess());
    }
}

public class ServiceImpl {
    public Response execute(Request request) {
        Response response = null;
                boolean isSuccess;
                if (returnMockResponse(request, notifyRqst)) {
                    isSuccess = true;
                } else {
                    isSuccess = eventRequest(notifyXmlRqst);
                }
        response = ResponseBuilder.createResponse(isSuccess);
        return response;
    }

    // Need to mock below private method and should return true.
    private boolean eventRequest(String request) throws Exception {
        return eventNotifyResponse.isIsSuccess();
    }
}

public class ResponseBuilder {
    public Response createResponse(boolean result) {
            Response response = new Response();
            response.setIsSuccess(result);
            return response;
    }    
}

默认情况下，在jUnit或jMock中是不可能的，您可以将private更改为public，也可以调用在内部调用private方法的public方法，并确保输入导致调用和覆盖private方法。

您尝试过

PowerMock.createPartialMock（ClassWithPrivateMethod.class，“NameOfMethodToMock”）

和

PowerMock.expectPrivate（mockObject，“NameOfMethodToMock”，argument1，argument2）

如关闭PowerMock的wiki中所述

或者也许看到这个问题的答案

您可以正常创建eventNotifyResponse的模拟，然后使用Whitebox设置私有（内部）字段

假设您的字段eventNotifyResponse是名为eventNotifyResponse的类型，则它的测试类类似于：

    EventNotifyResponse evtNotifyResponseMock = mock(EventNotifyResponse.class);
    when(evtNotifyResponseMock.isIsSuccess()).thenReturn(true);
    Whitebox.setInternalState(serviceImpl, "eventNotifyResponse", evtNotifyResponseMock);

Whitebox是Powermock的一个类（org.Powermock.reflect.Whitebox）。
setInternalState重载。在示例中，使用的参数为：

要注入的目标对象（正在测试的对象）

要设置的内部字段的名称（字符串）

值本身，在本例中为模拟值

不要模拟私有方法。在调用isIsSuccess（）时，只需模拟eventNotifyResponse以返回true。另外，为什么要将未使用的字符串传递给该方法？对该字符串进行一些条件检查，以便我传递字符串。@Manu，我们不能这样做，因为在调用eventNotifyResponse.IsSuccess（）之前；我们还有一些代码来验证其他一些逻辑，但我想跳过这些代码并返回true，当我们调用eventRequest（notifyXmlRqst）时，请看一下这个。可能重复
