In this example, we shall show you to test void methods. In JUnit Test Void Method example we will learn how we can test the void methods using the JUnit. In our previous tutorials, we have learned a lot about the JUnit and its various techniques about testing. But in our previous tutorials<\/a> we haven’t seen how we can test void<\/code> methods.<\/p>\n

You can read about JUnit<\/a> in Testing with JUnit<\/a>\"\" book.

\nIn this example, we will see how we can cover examples of some of the scenarios where we need to test the void methods. We will be using Maven<\/a> as our build and dependency tool for this example.<\/p>\n

1. Introduction<\/h2>\n

JUnit testing framework will help you test all your methods. It is a major tool in the arsenal of Java developers. We can test all type of methods irrespective of the method returning any value or not.<\/p>\n

In our previous tutorials<\/a>, we have seen many ways to test the methods those returning the value. In this example we will test those methods that don’t return any value<\/strong>.<\/p>\n

Tip<\/strong>
\nIf your method has no side effects, and doesn’t return anything, then it’s not doing anything.<\/div>\n

Above line is from JUnit docs and tells everything about the methods.<\/p>\n

2. Technologies Used<\/h2>\n

We will be using the following technologies in our example.<\/p>\n
