### Question:
TransactionalForumStructureService implements ForumStructureService { @Override public void saveJcommune(Jcommune jcommune) { componentDao.saveOrUpdate(jcommune); } TransactionalForumStructureService(SectionDao sectionDao, BranchDao branchDao, ComponentDao componentDao,
            JCommuneNotifier jCommuneNotifier); @Override void saveJcommune(Jcommune jcommune); @Override Jcommune getJcommune(); @Override void removeBranch(PoulpeBranch branch); @Override void moveBranch(PoulpeBranch branch, PoulpeSection toSection); @Override Jcommune deleteSectionWithBranches(PoulpeSection section); @Override void deleteSectionAndMoveBranches(PoulpeSection toRemove, PoulpeSection toReceiveBranches); @Override PoulpeBranch saveBranch(PoulpeSection inSection, PoulpeBranch notYetSavedBranch); @Override void moveBranch(PoulpeBranch branch, PoulpeBranch target); @Override void moveSection(PoulpeSection section, PoulpeSection target);  }### Answer:
@Test(dataProvider = "provideJcommuneWithSectionsAndBranches") public void testSaveJcommune(Jcommune jcommune) { sut.saveJcommune(jcommune); verify(componentDao).saveOrUpdate(jcommune); }
