LPS-44526 Add integration test
LPS-44526 Just call Util directly
LPS-44526 Source formatting
LPS-44526 This class is called UserGroupRoleLocalServiceTest, it should really test UserGroupRoleLocalService
LPS-44526 The test is not really testing the broken case, you have to populate the cache with null holder from UserGroupRolePersistenceImpl before creating new UserGroupRole
LPS-44526 All working at service level now, no need to use TransactionalTestRule
