There are already some tests that already use JUnit5 as well as some pending PRs (#3219, #3218, ...) to migrate more. This PR will migrate all (*) tests to JUnit5.
Migration includes:
Assertions

modifiers from test classes and methodsexpected

, simplyifing assertions...)I validated my changes using
./mvnw verify
and(*) Some tests use
org.junit.Rule
implementations that do not have a JUnit5 replacement and implementing these is non-trivial from what I can tell. Further there are some instances of other testing frameworks that do not yet support JUnit5. I plan on looking into these cases as well but deliberately did not include them in this PR.Checklist
