Top 5 Free Online Courses to Learn Eclipse and JUnit for Beginners in 2024 - Best of Lot

Both Eclipse and JUnit are two of the essential tools for Java Developers. Eclipse is a Java IDE, Integrated Development environment which allows you to code, run, and debug Java programs from a single window. At the same time, JUnit is a unit testing library that will automatically test your Java code. You can write JUnit tests, and then you can run them automatically using Maven or Gradle plugin at build time. You can further automate your build using Jenkins, which means your Unit test will run continuously and automatically, reporting any break at the earlier possible opportunity.

Many Java developers spend their whole workday on Eclipse writing code, running them, and debugging them. That's why you need to have a good understanding of both Eclipse in JUnit. It also helps to know your tools to be good at what you are doing.

In the past, I have shared some useful Eclipse and JUnit books to improve your knowledge and skills about these two fundamental tools. And today, I am going to share some of the free online courses from Udemy and Pluralsight, which you can join to improve your JUnit and Eclipse skills.

These courses are particularly suitable for beginners, and you will learn everything you need to work in Java effectively. By learning this tool at the start of your career, you will save a lot of time writing and running your code. Btw, intermediate developers can also benefit from these courses.

These courses are suitable for any Java developer who wants to learn Eclipse and JUnit or either technology from scratch. They are absolutely free, so there is no reason why you can't join them.

If you are starting with Java, I suggest you also take a look at  The Complete Java Masterclass by Tim Buchalka. Even though the course uses IntelliJIDEA, it's well worth learning Java from this course as It's the most up-to-date and comprehensive course for Java Programmers.

6 Best Free JUnit and Eclipse Courses for Java Programmers

Learning a new technology or programming language is not that easy. You need to spend considerable time learning and understanding the technology and the tools you need to work effectively, and Java is no different.

Eclipse and JUnit are two of the essential tools for Java developers, and a good knowledge of them goes a long way to becoming an effective and powerful Java developer.

When it comes to learning a new technology or tool, my 3 point rule is joining a course, reading a book, and doing a project. To learn Eclipse or JUnit, you can also adopt the same approach.

You can start with these courses, then follow these Eclipse and JUnit books, and once you have a good understanding of both technology and tool, you can start doing projects.

3. JUnit 5 Quick Start: Java Unit Testing  [Udemy Free Course]

JUnit is another skill that many Java developers possess but is not just good enough. Most of the Java developers I have met and interviewed know what a JUnit is and have written one or two trial JUnit tests, but they never really use JUnit to test their live project or new code they are writing every day.

Most of them will give you excuses like there is always delivery pressure, absolutely no time to write unit tests, or TDD. Still, the main reason for avoiding unit testing is often low confidence and not having enough skill and experience to write a unit test for any kind of code.

In a nutshell, this course will teach you:
  • how to create a new project for JUnit Tests
  • how to make, Run, and  Debug JUnit Tests
  • how to write Good Unit Tests
  • how to use assert methods
  • how to use necessary JUnit Annotations - @Test, @Before, @After, @AfterClass, @BeforeClass, @Suite
  • how to test Performance and Exceptions in Unit Tests
  • how to write Parameterized Tests
  • Adhere to JUnit Best Practices
  • How to understand test output and much more. 
This JUnit tutorial will help you bridge that gap and teach you all the essential concepts of unit testing and the JUnit testing framework.  And, most importantly, how to use Eclipse to write and run JUnit Tests for your Java code.
