如何使用模拟日常程序的模拟对象? [英] How to use mock object mimicing a daily routine program?

问题描述

我的程序有一个日常例行程序，类似于闹钟事件.假设是下午2点(时间是我电脑中的系统时间)，请为我做点事情.

My program has a daily routine, similar to an alarm clock event. Say, when it's 2pm(The time is the system time in my pc), do something for me.

我想做的是加快测试周期(我真的不想等待4天查看日常工作并检查错误.)我在

What I want to do is to speed up the testing period(I don't really want to wait 4 days looking at the daily routine and check errors.) I read on wiki of Mock object, the writer DID mention alarm clock program. I was so happy to see but still, don't know how to do it.

我是Mock Object的新手，我正在用Java编程.因此，JMock或EasyMock(或任何类似产品)对我来说可能还可以.

I am new to Mock Object, and I am programming in Java. So JMock or EasyMock(or any similar) might okay to me.

谢谢

推荐答案

每当需要获取当前时间时，请勿直接使用系统时钟-使用如下接口:

Whenever you need to get the current time, don't use the system clock directly - use an interface such as:

public interface Clock
{
    long currentMillis();
}

然后，您可以使用系统时钟来实现此目标，以进行生产，并通过伪造品进行测试，在其中您可以将伪造品设置为所需的任何时间.

You can then implement this with a system clock for production, and pass in a fake for tests, where you can set the fake to whatever time you want.

但是，您还需要模拟驱动系统的任何因素-是您明确地等待特定时间，还是其他东西调用了您的代码?

However, you'll also need to mock out whatever's driving your system - are you explicitly waiting for a particular time, or does something else call your code?
