如何通过mockito验证是否从其他具有相同类的方法调用

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

我想测试一些在同一个类中调用其他方法的方法.它们基本上是相同的方法，但具有不同数量的参数，因为数据库中有一些默认值.我在这个上显示

I want to test some methods that call others in the same class. They are basically the same methods, but with different numbers of arguments because there are some default values in a database. I show on this

public class A{
    Integer quantity;
    Integer price;        

    A(Integer q, Integer v){
        this quantity = q;
        this.price = p;
    }

    public Float getPriceForOne(){
        return price/quantity;
    }

    public Float getPrice(int quantity){
        return getPriceForOne()*quantity;
    }
}

所以我想测试调用getPrice(int)方法时是否调用了getPriceForOne()方法.基本上像平常一样调用 getPrice(int) 并模拟 getPriceForOne.

So I want to test if the method getPriceForOne() was called when calling the method getPrice(int). Basically call getPrice(int) as normal and mock getPriceForOne.

import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
....

public class MyTests {
    A mockedA = createMockA();

    @Test
    public void getPriceTest(){
        A a = new A(3,15);
        ... test logic of method without mock ...

        mockedA.getPrice(2);
        verify(mockedA, times(1)).getPriceForOne();
    }
}

请记住，我有一个更复杂的文件，它是其他人的实用程序，它们必须都在一个文件中.

Please keep in mind that I have a much more complicated file that's a utility for others and they must all be in one file.

推荐答案

你需要一个间谍，而不是一个模拟 A:

You would need a spy, not a mock A:

    A a = Mockito.spy(new A(1,1));
    a.getPrice(2);
    verify(a, times(1)).getPriceForOne();
