EasyMock 返回奇怪的值
我目前正在尝试学习如何使用easymock。我有以下代码：
List list = EasyMock.createMock(List.class);
EasyMock.expect(list.size()).andReturn(0);
EasyMock.replay(list);
EasyMock.verify(list);
至少对我来说，这应该可以工作——一个列表被初始化，其中没有任何内容，并且大小应该返回 0。但是，我收到以下错误：
java.lang.AssertionError:
Expectation failure on verify:
size(): expected: 1, actual: 0
我认为这很奇怪，所以我更改了将行中的 0 改为 1 并重新运行测试。我遇到了同样的错误。有谁知道我做错了什么？提前致谢！
I am currently trying to learn how to use easymock. I have the following code:
List list = EasyMock.createMock(List.class);
EasyMock.expect(list.size()).andReturn(0);
EasyMock.replay(list);
EasyMock.verify(list);
This, to me at least, should work -- a list is initialized with nothing in it and the size should return 0. I get the following error, however:
java.lang.AssertionError:
Expectation failure on verify:
size(): expected: 1, actual: 0
I thought this was weird, so I changed the 0 in the line to a 1 and reran the test. I got the same error. Does anyone know what I'm doing wrong? Thanks in advance!

在
replay之后和verify之前，您需要调用使用您的模拟的代码。该代码需要调用预期的方法（在本例中为size），并且仅该方法。错误消息意味着您将模拟设置为期望方法调用，但是当您去验证时，您从未在模拟上调用该方法，这是有道理的，因为您从未使用过模拟。after
replayand beforeverify, you need to invoke the code that uses your mock. That code needs to call the expected method (sizein this case) and only that method. The error message means you set your mock up to expect a method call, but when you went to verify, you never called the method on the mock, which makes sense because you never used the mock.
