The video tutorial discusses the differences between JUnit 5 and JUnit 4, focusing on changes in annotation names and usage, such as 'beforeAll' and 'afterAll' replacing 'beforeClass' and 'afterClass'. It also covers test grouping with tags, exception handling, and performance testing. New features in JUnit 5, like nested and repeated tests, are introduced, allowing for better test organization and execution.

• To disable a test

• To organize tests by scenarios

Which JUnit 5 feature allows a test to be executed multiple times?

• @RetryTest
