[英]Using mocked method argument to mock next steps
I have a method in my code that looks something like this: 我的代码中有一个看起来像这样的方法:
action.onResult(new Handler<MyClass>() {
@Override
public MyClass handle() { // Do something here }
}
}
I want to be able to mock it (using Mockito). 我希望能够模拟它(使用Mockito)。 Something like this: 像这样:
when(mockedAction.onResult(any(Handler.class))).thenReturn(firstArg.handle());
Meaning, I want to call the handle
method of the argument that's sent to the method onResult
. 意思是,我想调用发送给方法onResult
的参数的handle
方法。 I can't mock the handler because it uses inner methods of the calling class (I thought about using a private class but haven't reached a good enough solution) 我不能嘲笑处理程序,因为它使用了调用类的内部方法(我考虑过使用私有类,但尚未达到足够好的解决方案)
Motivation : This is an asynchronous callback mechanism that's used in a synchronous area. 动机 :这是一种异步回调机制,用于同步区域。 I want to mock the call to the handler itself in order to continue the flow synchronously in the code. 我想模拟对处理程序本身的调用,以便在代码中同步继续执行流程。
OK, UNTESTED but here is a possible use of ArgumentCaptor
for this scenario: 好的,未测试,但是在这种情况下可以使用ArgumentCaptor
:
final ArgumentCaptor<Handler> captor = ArgumentCaptor.forClass(Handler.class);
when(mock.onResult(captor.capture())).thenReturn(captor.getValue().handle());
Not sure however whether the captor has the "time" to initialize here. 但是,不确定捕获者是否具有在此处初始化的“时间”。
