EasyMock: Get real parameter value for EasyMock.anyObject()?
提问by Armen
In my unit tests I'm using EasyMock for creating mock objects. In my test code I have something like this
在我的单元测试中，我使用 EasyMock 来创建模拟对象。在我的测试代码中，我有这样的事情
EasyMock.expect(mockObject.someMethod(anyObject())).andReturn(1.5);
So, now EasyMock will accept any call to someMethod(). Is there any way to get real value that is passed to mockObject.someMethod(), or I need to write EasyMock.expect()statement for all possible cases?
所以，现在 EasyMock 将接受任何对someMethod(). 有没有办法获得传递给 的真实值mockObject.someMethod()，或者我需要EasyMock.expect()为所有可能的情况编写语句？

You can use Captureclass to expect and capture parameter value:
您可以使用Capture类来期望和捕获参数值：
Capture capturedArgument = new Capture();
EasyMock.expect(mockObject.someMethod(EasyMock.capture(capturedArgument)).andReturn(1.5);
Assert.assertEquals(expectedValue, capturedArgument.getValue());
Note that Captureis generic type and you can parametrize it with an argument class:
请注意，这Capture是泛型类型，您可以使用参数类对其进行参数化：
Capture<Integer> integerArgument = new Capture<Integer>();
Update:
更新：
If you want to return different values for different arguments in your expectdefinition, you can use andAnswermethod:
如果要为expect定义中的不同参数返回不同的值，可以使用andAnswer方法：
EasyMock.expect(mockObject.someMethod(EasyMock.capture(integerArgument)).andAnswer(
new IAnswer<Integer>() {
@Override
public Integer answer() {
return integerArgument.getValue(); // captured value if available at this point
}
}
);
As pointed in comments, another option is to use getCurrentArguments()call inside answer:
正如评论中所指出的，另一种选择是使用getCurrentArguments()call inside answer：
EasyMock.expect(mockObject.someMethod(anyObject()).andAnswer(
new IAnswer<Integer>() {
@Override
public Integer answer() {
return (Integer) EasyMock.getCurrentArguments()[0];
}
}
);
