Which is the better Java testing framework for Selenium automation testing: JUnit 5 or TestNG?
JUnit 5 is the latest version of JUnit, and it’s now the de facto standard in Java testing. And if you have been looking at different frameworks to build automation tests for your web applications, then you might have come across some confusion as to which framework should be used for Selenium automation testing. JUnit 5 or TestNG?
JUnit 5 and TestNG both offer a complete testing framework for Java application developers. Both frameworks also provide improvements over their predecessor for writing automated tests for web applications. This is done with minimal impact on the test code itself, making it easier to write automated web tests with either framework.
TestNG was originally developed by InfoQ, while JUnit 5 was developed by the JUnit team at Oracle. Both are open-source frameworks. However, TestNG has been around longer than JUnit 5, having been started in 2007, while JUnit 5 was released in 2016 as part of Java 9.
TestNG has its own approach to dealing with annotations. On the other hand, JUnit 5 allows you to use annotations from both JUnit 4 and TestNG annotations in a single project. As far as IDE support goes, both TestNG and JUnit 5 have good IDE support with plugins for popular IDEs such as IntelliJ IDEA and Eclipse.
