FrankChen021 opened a new pull request, #19874: URL: https://github.com/apache/druid/pull/19874
### Description Update `AGENTS.md` to require JUnit 5 (`org.junit.jupiter`) for new test cases and tell coding agents not to add new tests using JUnit 4 (`org.junit`). Druid currently supports both frameworks while legacy JUnit 4 tests remain in the repository. This guidance prevents new tests from extending JUnit 4 usage without requiring unrelated migration of existing tests. It does not affect Druid runtime behavior. ### Verification - Confirmed that JUnit 5 is configured across Druid modules. - Self-reviewed the complete diff against the target branch. - Ran `git diff --check`. - No runtime tests were run because this change only updates agent guidance. This PR has: - [x] been self-reviewed. - [x] added documentation for a repository testing requirement. -- This is an automated message from the Apache Git Service.
