Alexey Zotov updated CASSANDRA-16630:
-------------------------------------
Description:
h3. Overview
Currently C* uses JUnit4 (version 4.12) which is obsolete. There is a newer
version 4.13.2 which we could update to. However, JUnit4 is generally
considered to be outdated and it is reasonable to migrate to JUnit5.
Despite of having a syntax sugar in JUnit5 (assertThrow, lamda's support, ect),
there are no blockers that push us to move from JUnit4. The main motivation for
this initiative is rule of thumb to use up-to-date versions of the dependencies.
Obviously this change is not backward compatible with the open PRs and previous
C* versions. Therefore, it will require an additional effort for backporting
the changes and updating PRs that have tests. However, I believe it should not
be a blocker for this initiative.
h3. Action items (preliminary list)
# change JUnit4 to JUnit5 dependencies and make necessary changes in ant tasks
(https://ant.apache.org/manual/Tasks/junitlauncher.html)
# update syntax in all tests (imports, Before/After annotations, etc)
# update parameterized tests
# create a new version of {{OrderedJUnit4ClassRunner}} and update corresponding
tests
# update tests that use {{BMUnitRunner}} (as per
https://developer.jboss.org/docs/DOC-52953 it supports JUnit5)
