### Question:
ArchetypeServiceImpl implements ArchetypeService { @Override public void validate(final String alias) { checkNotEmpty(ALIAS_PARAM, alias); final Repository repository = resolveRepository(alias); if (repository == null) { throw new IllegalStateException(String.format("Repository %s cannot be resolved.", alias)); } validateArchetype(repository); archetypePreferencesManager.addArchetype(alias); archetypeListUpdatedEvent.fire(new ArchetypeListUpdatedEvent(ArchetypeListOperation.VALIDATE)); } ArchetypeServiceImpl(); @Inject  ArchetypeServiceImpl(final @Named("ioStrategy") IOService ioService,
                                final RepositoryService repositoryService,
                                final OrganizationalUnitService ouService,
                                final Event<ArchetypeListUpdatedEvent> archetypeListUpdatedEvent,

                                final POMService pomService); void onNewOrganizationalUnitEvent(final @Observes NewOrganizationalUnitEvent newOrganizationalUnitEvent); @Override void add(final GAV archetypeGav); @Override void add(final GAV archetypeGav,

@Test(expected = IllegalArgumentException.class) public void validateWhenInvalidAliasTest() { service.validate(null); }
@Test(expected = IllegalStateException.class) public void validateWhenOrgUnitIsNotAvailableTest() { mockArchetypesOrgUnitNotAvailable(); service.validate(COMMON_ARCHETYPE_ALIAS); }
@Test(expected = IllegalStateException.class) public void validateWhenRepositoryIsNotAvailableTest() { mockArchetypesOrgUnit(); final Archetype archetype = mock(Archetype.class); doReturn(ArchetypeStatus.VALID).when(archetype).getStatus(); doReturn(archetype).when(archetypeConfigStorage).loadArchetype(anyString()); doReturn(null).when(repositoryService).getRepositoryFromSpace(any(Space.class), anyString()); service.validate(COMMON_ARCHETYPE_ALIAS); }
