Mockito is an open-source testing framework used for unit testing of Java applications. It plays a vital role in developing testable applications. Mockito is used to mock interfaces so that a dummy functionality can be added to a mock interface that can be used in Unit Testing. Unit Testing is a type of software testing in which individual components of the software are tested. The major objective of using the Mockito framework is to simplify the development of a test by mocking external dependencies and using them in the test code. And as a result, Mockito provides a simpler test code that is easier to understand, more readable, and modifiable. Mockito can also be used with other testing frameworks like JUnit and TestNG.
JUnit framework is a Java framework that is also used for testing. Now, JUnit is used as a standard when there is a need to perform testing in Java. So in this article, we will be discussing test cases in a java application using Mockito and Junit.
Step 1: Create a Maven project in your favorite Java IDE (IHere we are using IntelliJ IDEA)
Step 2: When you have successfully created a maven project you have to add some dependencies in your pom.xml file. We have to add the following dependency in your pom.xml file.
Dependency for Mockito is as follows:
