This tutorial explains the use of JUnit in your project unit testing, while working with Java. After completing this tutorial you will gain sufficient knowledge in using JUnit testing framework from where you can take yourself to next levels.
We assume you are going to use JUnit to handle all levels of Java projects development. So it will be good if you have the knowledge of software development using any programming language, especially Java programming and software testing process.
