@zzzk1 Welcome to Apache EventMesh community!

Hi, @Pil0tXia. In #4768, there are three test cases that have been deleted, and I noticed 2 things.

• eventmesh-runtime/src/test/java/org/apache/eventmesh/runtime/admin/handler/EventHandlerTest.java are using Netty directly.
• This issue requires me to use Netty to support the deletion of those three test cases.

Am I understanding correctly?

@zzzk1 You can write unit tests on a case-by-case basis without specifically using Netty only for all of them.
