@nandakumar131 , thanks a lot for working on JUnit5 migration! For the dependencies, let's add them when they are needed (i.e. add them with the tests). We minimize the dependencies because Ratis is a library. We should make it easier to be consumed.

For JUnit5 migration, we may start with ratis-common since it only has a few tests. It can show how the migration works.

Thanks for the review @adoroszlai & @szetszwo.

@szetszwo, sure. will do.

FYI: The scope of the junit dependencies are of scope test, so it will not be part of Ratis's transitive dependencies.

@szetszwo, I have been working on limiting the changes just to ratis-common, but the test compilation started failing on ratis-server, ratis-test & ratis-examples as they extend BaseTest from ratis-common.

I will try to limit the changes on each PR to make the review process easier.

This PR will only update the parent pom.xml and ratis-common's pom.xml

Test-case changes will happen in follow-up PRs.

@nandakumar131 , I understand that the test dependencies are not transitive. That's a good point!

It is usually hard to remove dependencies. So I really oppose adding unused dependencies. Moreover, we have to handle it in case of CVEs.

Please include some change to use the dependencies in this pull requests.
