Essential Free Courses on Eclipse, JUnit, and Mockito for Java
Written on
Eclipse and JUnit are fundamental tools for Java developers. Eclipse serves as an Integrated Development Environment (IDE) that enables developers to write, execute, and debug Java applications seamlessly. On the other hand, JUnit is a library designed for unit testing, allowing developers to automate the testing of their Java code.
With JUnit, you can write tests and run them automatically during the build process using Maven or Gradle plugins. Moreover, integrating Jenkins into your workflow enables continuous testing, ensuring that any issues are detected promptly.
Java developers typically spend significant time in Eclipse, focusing on coding, executing, and debugging their applications. Therefore, a solid grasp of both Eclipse and JUnit is crucial for enhancing your programming efficiency and effectiveness.
Previously, I have recommended books on Eclipse and JUnit to deepen your understanding of these essential tools. Today, I will present a curated list of the best free online courses available on platforms like Udemy and Pluralsight, aimed at enhancing your skills in JUnit and Eclipse.
Additionally, I have included courses on Mockito, Test Driven Development (TDD), Cucumber, and Selenium, all of which are vital for test automation. These courses are particularly beneficial for beginners, providing everything you need to become proficient in Java. By mastering these tools early in your career, you can significantly reduce the time spent on coding and testing. Intermediate developers will also find value in these resources.
These courses are ideal for any Java developer looking to learn Eclipse and JUnit from the ground up. Many of them are completely free, making it easy to get started.
If you’re willing to invest a few dollars in a valuable skill such as unit testing, I highly recommend the course Learn Java Unit Testing with Junit & Mockito in 30 Steps on Udemy. It’s available for just $9.99 during sales, making it an affordable option for Java developers.
Top Free Online Courses for Java Developers in 2023
Acquiring a new technology or programming language can be challenging. It requires a significant investment of time to not only learn the technology itself but also the tools necessary for effective usage. This holds true for Java as well.
Eclipse and JUnit are critical for Java developers, and a comprehensive understanding of these tools can significantly enhance your development capabilities.
When embarking on a learning journey, I recommend a three-pronged approach: enroll in a course, read relevant literature, and undertake practical projects. You can apply this method for mastering Eclipse and JUnit.
Start with the suggested courses, follow up with the relevant books, and once you're comfortable with both the technology and tools, initiate your projects.
