测试是否调用了另一个方法

2022-01-14 00:00:00 mockito java junit powermock

所以我确定那里有类似的东西，但我已经搜索了一个小时，但还没有找到我正在寻找的东西.假设我有一个看起来像这样的类:

So I'm sure there is something like this out there but I have been searching for an hour and haven't found exactly what I am looking for. say I have a class that looks like this:

public class MyClass
{
    public void myMethod(boolean shouldCallOtherMethod)
    {
        if(shouldCallOtherMethod)
        {
            otherMethod();
        }
    }

    public void otherMethod()
    {
        System.out.println("Called");
    }
}

我该如何做这样的事情?

How do I make something like this work?

@Test
public void shouldCallMethod()
{
    MyClass myClass = new MyClass();
    myClass.myMethod(true)

    // verify myClass.otherMethod method was called
}

推荐答案

使用 Mockito，你可以做到 像这样监视真实物体:

Using Mockito, you can do spying on real objects like this: 

import org.junit.Test;
import static org.mockito.Mockito.*;
public class MyClassTest {
    @Test
    public void otherMethodShouldBeCalled() {
        MyClass myClass = new MyClass();
        MyClass spy = spy(myClass);

        spy.myMethod(true);
        verify(spy).otherMethod();
    }
}

有一些问题，请查看相关文档 也是如此.

There are some gotchas, so take a look at the relevant documentation as well.
