Practical Java Unit Testing with JUnit 5. Hello! My name’s Adrian and I’m a professional Java Developer. You’ve just found the highest rated course about JUnit on Udemy! Here are some examples chosen from the hundreds of reviews :

• “superb and very compact, the course got me started in just two hours”
• “excellent, well-explained, with real-word examples”
• “perfect for beginners! I feel like: oh, it’s so easy!”

According to statistics, nearly 80% of all Java developers write unit tests with JUnit, and my developing practice proves it. Unit testing is so important because it increases the quality of your code. It is a basic skill required by most employees, so for any Java Developer professional career, you have to master JUnit. You’ll only learn the practical aspects of unit testing with JUnit 5 – the latest version of the most popular Java unit testing framework.

I’ll introduce only the essential theory behind unit testing, and then dive straight into the code to get you started as quickly as possible. I’ll use an example of a simple, yet practical Java project to show you a variety of unit test types. You’ll also learn the best practices and coding standards for unit tests based on my developing experience. You can get started in just a few hours. This course also comes with additional exercises and a one-page cheat sheet for a quick JUnit 5 reference.
