How to check JUnit version refers to the process of determining the version of the JUnit testing framework that is currently being used in a Java project. JUnit is a popular unit testing framework for Java applications, and it is important to know the version of JUnit that is being used in order to ensure compatibility with other tools and libraries, and to take advantage of the latest features and bug fixes.
There are several ways to check the JUnit version that is being used in a Java project. One way is to use the `mvn dependency:tree` command, which will print out a dependency tree for the project, including the versions of all the dependencies, including JUnit. Another way is to use the `gradle dependencies` command, which will do the same thing for Gradle projects.
