使用 Mockito 跳过方法执行

我正在使用 Mockito 进行单元测试，并且我想跳过方法的执行。

我参考了这张票使用 Mockito 跳过行的执行。在这里，我假设 doSomeTask() 和 createLink() 方法位于不同的类中。但就我而言，这两种方法都在同一个类中（ActualClass.java）。

//Actual Class

public class ActualClass{
    
    //The method being tested
    public void method(){
        //some business logic
        validate(param1, param2);

        //some business logic
    }

    public void validate(arg1, arg2){
        //do something
    }
}

//Test class

public class ActualClassTest{

    @InjectMocks
    private ActualClass actualClassMock;

    @Test
    public void test_method(){

        ActualClass actualClass = new ActualClass();
        ActualClass spyActualClass = Mockito.spy(actualClass);

        // validate method creates a null pointer exception, due to some real time data fetch from elastic

        doNothing().when(spyActualClass).validate(Mockito.any(), Mockito.any());
        actualClassMock.method();
    }
}

由于执行 validate 方法时会出现空指针异常，因此我尝试通过监视 ActualClass 对象来跳过方法调用，如上面提到的票证中所述。尽管如此，问题仍未解决。验证方法被执行并创建一个空指针异常，因此无法覆盖实际的测试方法。

那么，如何跳过同一类中的 validate() 方法的执行。

I’m using Mockito for unit testing and I want to skip the execution of a method.

I referred to this ticket Skip execution of a line using Mockito. Here, I assume doSomeTask() and createLink() methods are in different classes. But in my case, both the methods are in the same class (ActualClass.java).

//Actual Class

public class ActualClass{
    
    //The method being tested
    public void method(){
        //some business logic
        validate(param1, param2);

        //some business logic
    }

    public void validate(arg1, arg2){
        //do something
    }
}

//Test class

public class ActualClassTest{

    @InjectMocks
    private ActualClass actualClassMock;

    @Test
    public void test_method(){

        ActualClass actualClass = new ActualClass();
        ActualClass spyActualClass = Mockito.spy(actualClass);

        // validate method creates a null pointer exception, due to some real time data fetch from elastic

        doNothing().when(spyActualClass).validate(Mockito.any(), Mockito.any());
        actualClassMock.method();
    }
}

Since there arises a null pointer exception when the validate method is executed, I’m trying to skip the method call by spying the ActualClass object as stated in the ticket I mentioned above. Still, the issue is not resolve. The validate method gets executed and creates a null pointer exception due to which the actual test method cannot be covered.

So, how do I skip the execution of the validate() method that is within the same class.

调用 method() 时，您必须始终使用您的间谍类。

   @Test
    public void test_method(){
        ActualClass spyActualClass = Mockito.spy(actualClassMock);

        doNothing().when(spyActualClass).validate(Mockito.any(), Mockito.any());
        spyActualClass.method();
    }

在实践中，

actualClassMock.method();

您必须使用

spyActualClass.method();

You must always use your spy class when calling method().

   @Test
    public void test_method(){
        ActualClass spyActualClass = Mockito.spy(actualClassMock);

        doNothing().when(spyActualClass).validate(Mockito.any(), Mockito.any());
        spyActualClass.method();
    }

In practice, instead of
