### Question:
CSVFileManager { public CSVFolder downloadFolder(CSVFolder folder) throws ServerCommunicationException, InvalidWriteEnablerException, ImmutableFileExistsException, RemoteFileDoesNotExistException, FailedToVerifySignatureException { return (CSVFolder) downloadObject(folder); } CSVFileManager(Communication connection);  CSVFileManager(Capability capability, Communication connection); void setRootCapability(Capability capability); CSVObject putObjectIntoFolder(CSVObject object, CSVFolder folder,
			String alias); CSVObject putObjectIntoCurrentFolder(CSVObject object, String alias); CSVFile uploadFile(CSVFile file); CSVFolder uploadFolder(CSVFolder folder); CSVFile downloadFile(CSVFile file); CSVFolder downloadFolder(CSVFolder folder); CSVFolder downloadFolder(String alias, CSVFolder fromFolder); CSVObject downloadObject(CSVObject object); CSVFolder downloadFolder(Capability capability); CSVFolder cd(String alias); CSVFolder getShareFolder(); CSVFolder getCurrentFolder(); CSVFolder getParentFolder(); CSVFolder replaceCurrentFolder(); CSVFolder getRootFolder(); void unlinkAliasFromCurrentFolder(String alias); void unLinkAliasFromFolder(String alias, CSVFolder folder); static final String SHARE_FOLDER; }### Answer:
@Test public void testFolderDownload() throws ServerCommunicationException, InvalidWriteEnablerException, ImmutableFileExistsException, FileNotFoundException, RemoteFileDoesNotExistException, FailedToVerifySignatureException { testFolderUpload(); CSVFolder newFolder = new CSVFolder(this.folder.getCapability()); newFolder = this.fileManager.downloadFolder(newFolder); Assert.assertTrue(newFolder.isValid()); Assert.assertTrue(newFolder.getContents().containsKey("hello")); }
