Mock an object in a method that is not a parameter

Question

I'm using EasyMock and junit to unit test a project I'm working on, but I'm stumped at this point. An example is below.

public ObjectNameHere methodOne(String location) {
    return this.SecondPart.getObjectByLocation(location);
}

I want to unit test this by checking that what the method returns is an instanceof ObjectNameHere... but how can I do that without mocking SecondPart (which requires I pass the method a mock object of SecondPart?) ??

Answer 1

Are you writing the test case for the method methodOne or getObjectByLocation . Because if it for methodOne then you need to mock the SecondPart object and expect some return value for the method getObjectByLocation . Or if it is for getObjectByLocation method then you have to write a test case for the SecondPart class.
