jUnit Testing training teaches its participants unit testing, JUnit framework and how to set it up and use it with Java projects.


This training of JUnit provides an introduction to Java's most-popular automated unit testing framework.

Participants will learn about the unit testing JUnit framework and how to set it up and use it with Java projects. Participants will also be familiar with the test-driven development as a methodology of writing highly reliable Java code.


At the end of this JUnit testing training, the participants will be able to:

  • Know JUnit's role in Java testing
  • Setup, integrate, and start using JUnit
  • Learn the differences between JUnit 3 and JUnit 4
  • Design, organize, and develop JUnit tests in either syntax of JUnit 3 or JUnit 4.
  • Learn to use best practices in both testing and software development
  • Start improving the quality and effectiveness of their software and tests

Preferred Audience:

Java developers, quality-assurance engineers, and development managers.

Total Duration - 1 Day


Great understanding of Java technology is needed to get the full benefit of this course. Prior experience in testing concepts (e.g. unit, integration, functional, load) is recommended.
