Starting with the new JUnit Jupiter Platform which is available for longer time there are much more options than with JUnit 4 or TestNG. This lecture will show the differences of JUnit Jupiter platform and how it can be used to write better unit- and or integration tests. It will be shown how to migrate to JUnit Jupiter platform and which things should be considered/changed based on the differences between JUnit Jupiter and JUnit 4/TestNG and which things have been changed in comparison to TestNG/JUnit 4. Furthermore things like dynamic tests will be taken a short overview and things like extensions will also taken into account.
