Description

JUnit5 is a powerful and flexible update to the JUnit framework, and it provides a variety of improvements and new features to organize and
describe test cases, as well as help in understanding test results：

1. JUnit 5 leverages features from Java 8 or later, such as lambda functions, making tests more powerful and easier to maintain, but Junit 4 still a Java 7 compatible version
2. JUnit 5 has added some useful new features for describing, organizing, and executing tests. For examples: Parameterized Tests and Conditional Test Execution may make our test code look simpler, Parallel Execution may make our test faster

 

More importantly, Junit4 is currently an inactive project, which has not released a new version for more than two years
