What is JUnit?
JUnit is a unti testing library for Java software.
Created by Kent Beck and Eric Gamma, JUnit belongs to the family of xUnit frameworks for various programming languages originating in the Kent Beck SUnit for Smalltalk. JUnit spawned an ecosystem of extensions - JMock, EasyMock, DbUnit, HttpUnit, and so on.
- junit.framework.TestCase extends junit.framework.Assert
What's new in JUnit 5?
Unlike previous versions of JUnit, JUnit 5 is composed of several different modules from three different sub-projects.
JUnit 5 = JUnit Platform + JUnit Jupiter + JUnit Vintage
The JUnit Platform serves as a foundation for launching testing frameworks on the JVM. It also defines the
TestEngineAPI for developing a testing framework that runs on the platform. Furthermore, the platform provides a Console Launcher to launch the platform from the command line and build plugins for Gradle and Maven as well as a JUnit 4 based Runner for running any
TestEngine on the platform.
JUnit Jupiter is the combination of the new programming model and extension model for writing tests and extensions in JUnit 5. The Jupiter sub-project provides a
TestEngine for running Jupiter based tests on the platform.
JUnit Vintage provides a
TestEngine for running JUnit 3 and JUnit 4 based tests on the platform.
