What is the purpose of JUnit 5 @Nested annotation

Question

In JUnit 5 there is a new abstract: @Nested.

I understand how this works, I understand why we use a nested class, I just don’t understand why we need to have a nested test class in our test.

Answer 1

Annotation @Nestedallows you to have an inner class, which is essentially a test class, allowing you to group several test classes under the same parent (with the same initialization).
