How to set properties on a Mocked Object using EasyMock?

[Arjun Reddy]

Hi All,

I have a piece of code as below:

MyObject myMockObject = EasyMock.createMock(MyObject.class);
EasyMock.expect(myMockObject.getId()).andReturn(1).anyTimes();
EasyMock.replay(myMockObject);

Now from the calling method, I want to set id to a different value. How do I do it?

Thanks

The calling object doesn't know it has a mock. It just makes calls to the object normally. This causes awkwardness if the object you are mocking out has getters and setters as the mock doesn't have logic like this. You would have to set expectations on the mock that you call a sequence like:
1) get() - returns 2
2) set(3)
3) get() - returns 3

You might consider writing your own mock that can store state and just checks if the method you want to mock out is called.

You could try

MyObject myMockObject = EasyMock.createMock(MyObject.class);
EasyMock.expect(myMockObject.getId()).andReturn(1).anyTimes();
myMockObject.setId(EasyMock.anyObject());
EasyMock.replay(myMockObject);

Assuming that your calling method first calls the get and then the set
