Why does Python give a MagicMock object instead of a return_value?

edit

The MagicMock object in Python is a substitute for a specific type of object that is used during testing. It is designed to allow developers to define the behavior of a particular object without having to create a real instance of that object.

When a MagicMock object is returned instead of a return value, it typically means that the object being tested has not yet been fully implemented or that the developer wants to test a specific behavior of the object. In this case, the MagicMock object can be used to simulate the expected behavior of the fully implemented object.

The MagicMock object can be configured to return specific values or to behave in specific ways when certain methods are called on it. This allows developers to thoroughly test the behavior of their code without having to rely on complex real-world scenarios.
