What are some advanced mocking techniques in Mockito?

Advanced mocking techniques in Mockito include argument matchers, spies, and custom answer implementations. Would you like to know more about any specific technique?

Can you explain how to use argument matchers?

Sure! Argument matchers allow you to specify conditions for the arguments passed to mocked methods. For example, you can use anyInt() to match any integer.

What about using spies? How do they differ from mocks?

Spies in Mockito allow you to wrap real objects and track interactions with them. Unlike mocks, spies can call real methods unless they are stubbed.

Can you give an example of a custom answer implementation?

Absolutely! You can use thenAnswer() to define a custom behavior for a mocked method. For instance, you can return different values based on the input.
