如何使用EasyMock测试void方法 [英] How to test void methods using EasyMock

问题描述

我已经看到了一些关于此的问题，但我似乎无法理解我的特定问题的任何答案。

I've seen a few questions out there regarding this but I can't seem to make sense of any of the answers for my particular problem.

我有一个模拟对象，让我们调用object1，我发送一些方法进行测试，让我们调用testMethod（）。所以我最终打电话给

I have a mock object, lets call "object1", which I send to some method for testing, lets call testMethod(). So I end up calling

testMethod(object1);

进行测试。现在在这个testMethod的某个地方，会有一个部分调用方法

for testing. Now somewhere in this testMethod, there will be a part where it calls a method

object1.toggleDisplay();

这是一种void方法。如果方法类似于

which is a void method. If the method were like

object1.getDisplay()

它实际上返回的东西，我通常做

where it actually returns something, I usually do

EasyMock.expect(object1.getDisplay()).andReturn(whatever);

然而，这是一种无效方法，我想测试一下这确实是召唤了一定次数。最简单的方法是什么？

However, this is a void method, and I would like to just test that this has been indeed been called for a certain amount of times. What is the easiest way to do this?

谢谢

推荐答案

如果在过去几年里事情没有改变，那么在设定期望时你会使用 expectLastCall 。

If things haven't changed in the last few years, you use expectLastCall when setting up your expectations.

object1.toggleDisplay();
object.expectLastCall();
