What's the purpose of the JUnit 5 @Nested annotation
<p>In JUnit 5, there is a new annotation: <a href="https://junit.org/junit5/docs/current/api/org.junit.jupiter.api/org/junit/jupiter/api/Nested.html" rel="noreferrer"><code>@Nested</code></a>.</p>
<p>I understand how the annotation works, I understand why we use nested classes,
I just don't understand why we need to have <em>nested test</em> classes.</p>
