I’m trying to understand how to use the doCallRealMethod function in Mockito. I’m working on a project where I need to invoke the actual method of a mocked object while keeping some methods mocked. Could anyone provide guidance or examples on how this is achieved?
Hey! Using doCallRealMethod can be a bit tricky at first. You use it when you want a mock object to execute the actual method logic instead of the default mock behavior. You typically call it like this: doCallRealMethod().when(mockObject).methodName(). This comes in handy when you have partially mocked objects. It helped me a lot in testing real functionality while maintaining control over other mock methods. Hope it helps!
I’ve faced similar situations before! To use doCallRealMethod, ensure your mock object is prepared to partially execute real methods. Imagine testing a template pattern where the base method should run real logic. You can invoke doCallRealMethod().when(mockObject).methodToInvoke() to let some methods process naturally. It’s essential for integration tests where you need genuine behavior without skipping test coverage for real method logic.
Here’s how I’ve approached it: use doCallRealMethod for situations where you need fine-grained control over which methods are real and which are mocked. Say you have a class with a method that interacts with external systems but you still want to test its logic. For this, just mock the dependent parts and use doCallRealMethod().when(mockObject).yourMethod(). This way, you validate the method’s real behavior without the noise from other components.
