Project Setup for Application
Now, that the project setup is ready, let us look into an example to understand how to write and run test cases of JUnit using the Maven tool.
Step 1: Create a new package in the `src/test/java`, right-click on `src/test/java` > new > package.
Step 2: Create a class in the package and name it as per your requirement. i.e. `Addition`. To create a class, right-click on package > new > class
Step 3: Write the logic which you want to test in `Addition.java`.
Java
//Java code to demonstrate addition operation package project; public class Addition { public int sum(int a, int b) { return a+b; } } |
Step 4: Now, create a test case inside the package by right click on the package > new > others > java > JUnit > JUnit test case.
JUnit 5 – @RepeatedTest
JUnit 5 is a widely used testing framework in the Java ecosystem. It is the successor of JUnit 4 and is designed to address its limitations. JUnit framework allows the developers to write and run the tests for their Java code. These tests help ensure that the code functions correctly and continues to work as expected as changes are made. JUnit 5 provides a variety of annotations and one such annotation is `@RepeatedTest`. In this article, let us understand about @RepeatedTest annotation in JUnit 5.
