This will not only help you in your current project but also increase your chances of getting a job with better pay. You can use these online courses to get up-to-speed with JUnit and Mockito. In the past, I have shared some great books for learning unit testing in Java, and today, I am going to share some of the online courses you can use to learn JUnit 5 or Jupiter, the latest version of JUnit library, and Mockito to write a unit test for your Java application. As long as you can accept the fact, and you are willing to learn unit testing in Java using JUnit and Mockito, you are in good shape. For example: toCelcius()).ĭon't worry if you haven't written any unit tests. Unit tests are at the lowest level and typically check a single method to confirm that they return the correct result. In fact, every good software developer must know how to write unit tests, and nearly all Java jobs ask for unit testing skills, and those who don't mention it assume that you already know unit testing. Whatever your reason for not writing a unit test, I don't think it's going to work anymore because, in today's world of DevOps and automation, there is increased focus on code reviews, unit testing, and integration testing, and you just can't get away with not writing tests. When I ask them why don't you write unit tests, they come up with many excuses like they don't have time for writing unit tests, there is always deadline pressure, and some of the honest guys will tell you that they tried writing but give-up after 10-15 minutes due to difficulty in testing their code. I often meet and work with Java developers who know Java well but haven't written a single unit test. You may already know that JUnit and Mockito are two of the most popular testing libraries for Java applications, and you will find them in almost every Java application classpath. Today, we're going to talk about JUnit and unit testing, one of the key skills for any software developer.
