java verify void method calls n times with mockito

## Verifying void Method Calls N Times with Mockito in Java: A Comprehensive Guide

Mockito is a powerful and widely used Java mocking framework that simplifies unit testing. One of its core functionalities is the ability to verify how many times a method on a mocked object has been called. This is particularly useful when dealing with `void` methods because you can't directly assert their return value.

This tutorial provides a detailed explanation of how to verify `void` method calls `N` times using Mockito, covering various scenarios, nuances, and best practices.

**1. Understanding the Basics: Mocking and Verification**

* **Mocking:** Mocking involves creating objects that simulate the behavior of real dependencies. This allows you to isolate the unit of code you are testing and control the environment it operates in. Mock objects can be programmed to return specific values, throw exceptions, or perform certain actions when their methods are called.
* **Verification:** Verification is the process of confirming that a specific interaction occurred between the System Under Test (SUT) and the mocked dependency. In Mockito, you use the `verify()` method to check if a method was called, and how many times it was called. This is essential for validating the behavior of your code and ensuring that dependencies are being used as expected.
