This is a powerful feature that allows you to observe the behavior of your code in a non-intrusive way. In this example, we create a LinkedList object and then create a spy of it using Mockito. This spy object behaves just like the original list, but it also allows us to track its interactions and even change its behavior if we want to. Continue reading for more detailed usage and advanced scenarios. This is the most basic use of Mockito spy and a good starting point for beginners. In the example above, we first create a LinkedList object. We then create a Mockito spy of this list.

All documentation is kept in javadocs because it guarantees consistency between what's on the web and what's in the source code. It allows access to documentation straight from the IDE even if you work offline.

Python Built-in Functions. Mockito Verify in Java explains Mockito verify, for verifying interactions between mock objects and code in Java unit tests. Explore now. Mockito is a Java framework used for mocking and unit testing Java applications. Additionally, it allows us to call all the normal methods of the object.
