In main branches there have been a number of cleanup in tests.
These cleanups have removed the use of hamcrest and migrated unit test assertions to assertj.
The cleanups have been tracked in this epic: https://issues.redhat.com/browse/DROOLS-6929
Not all these cleanup have been backported to 7.67.x and 7.67.x-blue branches.
This makes cherrypicking of patches from main harder or impossible.
This issue is to backport to 7.67.x and 7.67.x-blue the cleanups
