### Question:
DatabaseServerConfigService extends AbstractArchivistService<DatabaseServerConfig> implements ResourceBasedCrnProvider { public DatabaseServerConfig getByName(Long workspaceId, String environmentCrn, String name) { Optional<DatabaseServerConfig> resourceOpt = repository.findByNameAndWorkspaceIdAndEnvironmentId(name, workspaceId, environmentCrn); if (resourceOpt.isEmpty()) { throw new NotFoundException(String.format("No %s found with name '%s' in environment '%s'", DatabaseServerConfig.class.getSimpleName(), name, environmentCrn)); } MDCBuilder.buildMdcContext(resourceOpt.get()); return resourceOpt.get(); }  Set<DatabaseServerConfig> findAll(Long workspaceId, String environmentCrn); DatabaseServerConfig create(DatabaseServerConfig resource, Long workspaceId, boolean test); DatabaseServerConfig update(DatabaseServerConfig resource); DatabaseServerConfig release(String resourceCrn); @Override DatabaseServerConfig delete(DatabaseServerConfig resource); DatabaseServerConfig getByName(Long workspaceId, String environmentCrn, String name); DatabaseServerConfig getByCrn(String resourceCrn); Optional<DatabaseServerConfig> getByCrn(Crn resourceCrn); Optional<DatabaseServerConfig> getByClusterCrn(String clusterCrn); DatabaseServerConfig deleteByCrn(String crn); @Override JpaRepository repository(); Set<DatabaseServerConfig> getByCrns(Set<String> crns); String testConnection(String crn); String testConnection(DatabaseServerConfig resource); String createDatabaseOnServer(String serverCrn, String databaseName, String databaseType, Optional<String> databaseDescription); @Override AuthorizationResourceType getResourceType(); @Override String getResourceCrnByResourceName(String resourceName); @Override List<String> getResourceCrnListByResourceNameList(List<String> resourceNames); @Override List<String> getResourceCrnsInAccount();  }### Answer:
@Test public void testGetByNameFound() { when(repository.findByNameAndWorkspaceIdAndEnvironmentId(SERVER_NAME, WORKSPACE_ID, ENVIRONMENT_CRN)).thenReturn(Optional.of(server)); DatabaseServerConfig foundServer = underTest.getByName(WORKSPACE_ID, ENVIRONMENT_CRN, server.getName()); assertEquals(server, foundServer); }
@Test public void testGetByNameNotFound() { thrown.expect(NotFoundException.class); when(repository.findByNameAndWorkspaceIdAndEnvironmentId(SERVER_NAME, WORKSPACE_ID, ENVIRONMENT_CRN)).thenReturn(Optional.empty()); underTest.getByName(WORKSPACE_ID, ENVIRONMENT_CRN, server.getName()); }
