### Question:
Count extends FsCommand { @Override protected void processOptions(LinkedList<String> args) { CommandFormat cf = new CommandFormat(1, Integer.MAX_VALUE, OPTION_QUOTA, OPTION_HUMAN, OPTION_HEADER); cf.parse(args); if (args.isEmpty()) { args.add("."); } showQuotas = cf.getOpt(OPTION_QUOTA); humanReadable = cf.getOpt(OPTION_HUMAN); if (cf.getOpt(OPTION_HEADER)) { out.println(ContentSummary.getHeader(showQuotas) + "PATHNAME"); } } Count(); @Deprecated  Count(String[] cmd, int pos, Configuration conf); static void registerCommands(CommandFactory factory); static final String NAME; static final String USAGE; static final String DESCRIPTION; }### Answer:
@Test public void processOptionsHeaderNoQuotas() { LinkedList<String> options = new LinkedList<String>(); options.add("-v"); options.add("dummy"); PrintStream out = mock(PrintStream.class); Count count = new Count(); count.out = out; count.processOptions(options); String noQuotasHeader = " DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME"; verify(out).println(noQuotasHeader); verifyNoMoreInteractions(out); }
@Test public void processOptionsHeaderWithQuotas() { LinkedList<String> options = new LinkedList<String>(); options.add("-q"); options.add("-v"); options.add("dummy"); PrintStream out = mock(PrintStream.class); Count count = new Count(); count.out = out; count.processOptions(options); String withQuotasHeader = " QUOTA REM_QUOTA SPACE_QUOTA REM_SPACE_QUOTA " + " DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME"; verify(out).println(withQuotasHeader); verifyNoMoreInteractions(out); }
