Mockito的argumentsCaptor示例 [英] Example of Mockito's argumentCaptor

问题描述

任何人都可以给我提供一个示例，演示如何使用org.mockito.ArgumentCaptor类以及它与Mockito附带的简单匹配器的区别.

Can anyone please provide me an example showing how to use the org.mockito.ArgumentCaptor class and how it is different from simple matchers that are provided with mockito.

我阅读了所提供的Mockito文档，但是并没有清楚地说明它，没有一个人能够清楚地解释它.

I read the provided mockito documents but those doesn't illustrate it clearly, none of them are able to explain it with clarity.

推荐答案

我完全同意@fge所说的内容.让我们来看一个例子. 考虑您有一种方法:

I agree with what @fge said, more over. Lets look at example. Consider you have a method:

class A {
    public void foo(OtherClass other) {
        SomeData data = new SomeData("Some inner data");
        other.doSomething(data);
    }
}

现在，如果要检查内部数据，可以使用捕获器:

Now if you want to check the inner data you can use the captor:

// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);

// Run the foo method with the mock
new A().foo(other);

// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());

// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);
