About The Video
Watch this video to explore the key differences between JUnit 4 and JUnit 5!
Here are the key differences between JUnit 4 and JUnit 5:
JUnit 4 is a single package, while JUnit 5 is modular with JUnit Platform, JUnit Jupiter, and JUnit Vintage.
JUnit 4 requires Java 5 or above, while JUnit 5 needs Java 8 or higher.
JUnit 4 lacks third-party integration support, but JUnit 5 supports build tools and IDEs like Eclipse, Visual Studio, and IntelliJ.
JUnit 4 assertions are in org.junit.Assert, while JUnit 5 assertions are in org.junit.jupiter.Assertions.

Key Topics Covered
Java Version Requirements:
JUnit 4 requires Java 5 or above. JUnit 5 requires Java 8 or higher, leveraging features from Java 8 such as Lambda functions to make tests more powerful and easier to maintain.
Features and Usability:
JUnit 5 introduces useful features for describing, organizing, and executing tests. Enhanced display names and hierarchical test organization in JUnit 5. JUnit 5 supports all popular build tools and IDEs, unlike JUnit 4.
Library Organization:
JUnit 5 is modular, organized into multiple libraries, allowing inclusion of only necessary features into projects. JUnit 4 is a single package, with all features bundled together.
Extensions and Integration:
JUnit 5 allows using multiple extensions simultaneously, which JUnit 4 does not support.
Additional Information:
The video is a brief comparison between JUnit 4 and JUnit 5. Mention of JUnit 5's compatibility with build systems like Maven and Gradle for easy integration of required libraries.
