### Question:
Formats { public static String toSizeUnitWithColor(Long size, LongWarning warning) { String[] ansi = colorAnsi(size, warning); return ansi[0] + toSizeUnit(size) + ansi[1]; }  static void disableAnsi(); static void setCleanClearTerminal(); static void setTextClearTerminal(); static String toMBWithColor(long bytes, LongWarning warning); static String toColor(long value, LongWarning warning); static String red(String value); static String yellow(String value); static String toMB(long bytes); static String toSizeUnitWithColor(Long size, LongWarning warning); static String toSizeUnit(Long size); static String toFixLengthSizeUnit(Long size); static String toTimeUnit(long millis); static String formatUsage(Usage usage); static String formatUsageWithColor(Usage usage, LongWarning warning); static String[] colorAnsi(long value, LongWarning warning); static String[] colorAnsi(double value, DoubleWarning warning); static String rightStr(String str, int length); static String leftStr(String str, int length); static String shortName(String str, int length, int rightLength); static String join(List<String> list, String delim); static long parseFromSize(String str); static void clearTerminal(); static final long MB_SIZE; static boolean isWindows; }### Answer:
@Test public void toSizeUnitWithColorInputNullNullOutputNullPointerException() { final Long size = null; final LongWarning warning = null; thrown.expect(NullPointerException.class); Formats.toSizeUnitWithColor(size, warning); }
