Top 5 Free Online Courses to Learn Eclipse and JUnit for Beginners in 2021 - 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.





5 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.


1. Eclipse IDE for Beginners: Increase Your Java Productivity

This is another beginner-level course on Eclipse for Java developers. You can take this course to learn how to develop a Java application with Eclipse.

The course will teach you how to install Eclipse and customize Eclipse for your environment using valuable plugins. You will also learn how to create Java applications in Eclipse and run and debug them right from Eclipse.

The course also teaches you to use many Eclipse productivity techniques, such as navigating the source code, generating source code, and creating unit tests. The course wraps by showing you how to import and export projects from Eclipse.

2. 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.

3. Eclipse tips and tricks

As the title suggests, this course is focused on teaching some useful Eclipse tips and tricks. Most Java developers remain content by just knowing how to create a Java project and run that from Eclipse.

They never really utilize the full potential of Eclipse by learning keyboard shortcuts and productivity tips and tricks like the one shown in this course.

This course tells you how to run and debug your program and some advanced tips about dealing with character encoding, Eclipse-built path configuration, using Maven with Eclipse, and faster installing of the plugin you need for better productivity.

It also teaches you how to work behind a corporate proxy and connect to the maven repository and Eclipse marketplace from a corporate network. Overall, a fantastic course to upgrade your Eclipse knowledge free of cost.


4. Eclipse Tutorial For Beginners [Free Udemy Course]

This is one of the excellent courses to learn the basics of Eclipse for free. The course is designed for beginners and first times, and it not only teaches and shows how to do stuff in Eclipse.

In this course, you go on a fun ride with Eclipse.

After completing the course, you should have many Eclipse tips and tricks up your sleeve. You will also understand various features of Eclipse like Views, Perspectives, Debugger, Save Actions, Plugins, and Code Generation.

The course will also improve your productivity with Eclipse Shortcuts, and you will also learn to import projects from Git and the basics of Maven projects. Overall an excellent course to start with Java Development with Eclipse.

5. Unit Testing In Java With JUnit [Pluralsight]

This is another excellent unit testing course for Java developers from one of my favorite instructors, John Sonmez. In this course, John explains the basics of JUnit and guides you to write your first unit tests.

Once the basic is covered, you will be introduced to the advanced concept, which will help you write clean tests and use best practices like DRY to create a maintainable test code.

After that, you will learn how to integrate JUnit with your existing Ant or Maven build system and how you can automate the creation of JUnit reports.

Finally, we'll wrap things up by going beyond the basic uses of JUnit by learning how to use stubs and mocks to really isolate classes, and we'll also learn how to use JUnit for more than just unit testing.

In short, an excellent course to learn JUnit quickly and start writing your first unit test. Btw, this course is not really free. You need a Pluralsight membership to access this course. A monthly membership will cost you around $29, and the annual one will be around $299, which gives you access to more than 5000 programming and development courses.

Though I encourage you to join Pluralsight to give your learning a boost, if you want, you can also take this course for free by signing up for a 10-day free trial, which is more than enough to complete this course.

That's all about some of the Free JUnit and Mockito online training courses you can take to learn and improve your unit testing skills in Java. As I have said many times, unit testing skill is essential for professional software developers. There is no excuse for not writing automated unit and integration tests at the age of DevOps. The candidate's unit testing skill is also tested during the interview, and candidates with excellent unit testing skills are often preferred.
